**Review of Concepts**

**Cost Price (C.P.)**= The price at which an article is purchased is called its Cost Price.

**Selling Price (S.P.)**= The price at which an article is sold is called its Selling Price.

**Overhead Expenses**= Sometimes apart from paying the cost of an article a person has to spend money on transportation, labor charges, repair, sales tax, etc. Such expenses are known as Overhead Expenses

**Marked Price (M.P.)**= In big shops and departmental stores, every article is tagged with a card and its price is written on it. This is called the Marked Price of that article, abbreviated as M.P.

**List Price**= Items that are manufactured in a factory are marked with a price according to the list supplied by the factory at which the retailer is supposed to sell them. This price is known as the List Price of the article.

**Discount**= In order to give a boost to the sale of an item or to clear the old stock sometimes the shopkeeper offer a certain percentage of rebate on the marked price. This is known as a Discount.

**Successive Discount**= Suppose a 20% discount is given on the marked price of an article and further, a discount of 10% is given at the reduced price. Then we can say that discounts of 20% and 10% are given in the article.

**Tax**= A compulsory contribution to the state revenue, levied by the government and added to the cost of goods and services is called Tax. It is always reckoned as a percentage of the sale.

**Difference between Marked Price and Sale Price**= The price marked on an article is called its Marked Price or List Price whereas the price at which an article is offered to the customer is called Sale Price.

**Ex-7A**

**1. Find the Gain Percent or Loss Percent, when:(i) C.P.= ₹750, S.P.= ₹875 (ii) C.P.= ₹126, S.P= ₹94.50(iii) C.P.= ₹80.40, S.P= ₹68.34 (iv) C.P.= ₹58.75, S.P= ₹51.70**

**Solution:**

(i) C.P.= ₹750 and S.P.= ₹875

∴ Gain= S.P. – C.P. = ₹(875-750)= ₹125

Now Gain%= (125/750) * 100= 16.67%

(ii) C.P.= ₹126, S.P= ₹94.50

∴ Loss= C.P. – S.P. =₹(126-94.50)= ₹31.50

Now Loss%= (31.50/126) * 100= 25%

(iii) C.P.= ₹80.40, S.P= ₹68.34

∴ Loss= C.P. – S.P. =₹(80.40 – 68.34)= ₹12.06

Now Loss%= (12.06/80.40) * 100= 15%

(iv) C.P.= ₹58.75, S.P= ₹51.70

∴ Loss= C.P. – S.P. =₹(58.75 – 51.70)= ₹12.06

Now Loss%= (7.05/58.75) * 100= 12%

**2. Ranjit Purchased an almirah for ₹5,248 and paid ₹127 for its transportation. He sold it for ₹6,020. Find his Gain Percent or Loss Percent?**

**Solution:** C.P. of an almirah= ₹5248

Spent on transportation= ₹127

Net C.P. of almirah= ₹(5248+127) =₹5375

S.P. of almirah= ₹6020

Gain= ₹(6020-5375) =₹645

Gain%= (645/5375) * 100= 12%

**3. Ahmed purchased an old scooter for ₹14,625 and spent ₹3,225 on its repairs. Then, he sold it for ₹16,422. Find his Gain Percent or Loss Percent**

**Solution:** C.P. of an old scooter= ₹14625

Spent on repair= ₹3225

Net C.P. of an old scooter= ₹(14625+3225)= ₹17850

S.P. of an old scooter= ₹16422

Loss= ₹(17850-16422)= ₹1428

Loss%= (1428/17850) * 100= 8%

**4. A man buys two cricket bats, one for ₹1,360 and the other for ₹1,040. He sells the first bat at a gain of 15% and the second one at a loss of 15%. Find his Gain Percent or Loss Percent in the whole transaction?**

**Solution: **C.P. of first bat= ₹1360

Gain%= 15%

S.P.= C.P. * (100+Gain%)/100= 1360 * (100+15)/100= ₹1564

C.P. of the second bat= ₹1040

Loss%= 15%

S.P.= C.P. * (100-Loss%)= 1040 * (100-15)/100= ₹884

∴ Total C.P. = ₹(1564+884)= ₹2448

Total S.P. =₹(1360+1040)= ₹2400

∴ Gain= S.P. – C.P. = ₹(2448-2400)= ₹48

Gain %= (48/2400) * 100= 2%

**5. Nandlal bought 20 dozen notebooks at ₹156 per dozen. He sold 8 dozens of them at 10% gain and the remaining 12 dozens at 20% gain. What is his Gain Percent in the whole transaction?**

**Solution:** C.P. per dozen= ₹156

C.P. of 20 dozen notebooks= 156 * 20= ₹3120

C.P. of 8 dozen notebook= 156 * 8= ₹1248

Gain= 10% of 1248= 124.80

S.P. of 8 dozen notebooks= 1248 + 124.80= ₹1372.80

Now C.P. of 12 dozen notebooks= 156 * 12= ₹1872

Gain= 20% of 1872= ₹374.40

S.P. of 12 dozen notebooks= 1872 + 374.40= ₹2246.40

Total S.P. of 20 dozen notebooks= 1372.80 + 2246.40= ₹3619.20

Total Gain= 124.80 + 374.40= ₹499.20

∴ Gain%= (499.20/3120) * 100= 16%

**6. Heera bought 25Kg of rice at ₹48 per Kg and 35Kg of rice at ₹60 per Kg. He sold the mixture at ₹66 per Kg. Find his Gain Percent?**

**Solution:** C.P. of 1 Kg rice= ₹48

C.P. of 25 Kg rice= 25 * 48= ₹1200

C.P. of another 1 Kg rice= ₹60

C.P. of 35 Kg rice= 60 * 35= ₹2100

C.P. of (25+35=60) Kg rice= ₹1200 + ₹2100= ₹3300

Now S.P. of 1 Kg rice= ₹66

∴ S.P. of 60 Kg rice= 66 * 60= ₹3960

Gain= S.P. – C.P. = 3960 – 3300= ₹660

Gain%= (660/3300) * 100= 20%

**7. If the selling price of an article is (4/5)th of its cost price, Find the Loss Percent?**

**Solution:** C.P. = x

S.P. = (4/5)x

Loss= x – (4x/5)= x/5

Loss%= (x/5)/x *100= 20%

**8. If the selling price of an article is 1 ^{1}⁄_{3} of its cost price, find the Gain Percent?**

**Solution:** C.P.= x

S.P.= 4x/3

Gain= (4x/3) – x= x/3

Gain%= (x/3)/x * 100= 100/3% = 33^{1}⁄_{3}%

**9. A man sold a table for ₹2,250 and gained one-ninth of its cost price. Find(i) Cost Price of the table (ii) Gain Percent earned by the man**

**Solution:** S.P= ₹2250

C.P.= x

Gain= 1/9

C.P. = (1/9)x

S.P. = C.P. + Gain= *x *+ (1/9)x = 10x/9

So, 10x/9 = ₹2250

x= 2025

(i) Cost Price= ₹2025

(ii) Gain= S.P. – C.P. = ₹225

Gain% = (225/2025) * 100= 100/9 = 11.11%

**10. By selling a pen for ₹195, a man loses one-sixteenth of what it cost him. Find (i) Cost Price of the pen (ii) Loss Percent**

**Solution:** S.P. = ₹195

C.P. = x

Loss= 1/16

C.P. = 1/16 * x = x/16

S.P. = C.P. – Loss = x – x/16 = 15x/16

So, 15x/16 = 195

x= ₹208

Now C.P. = ₹208

Loss= 208 * 1/16 = ₹13

Loss%= (13/208) * 100 = 25/4% = 6.25%

**11. A cycle was sold at a gain of 10%. Had it been sold for ₹99 more, the gain would have been 12%. Find the Cost Price of the cycle?**

**Solution:** Let the cost price of the cycle = ₹x

Gain = 10%

We know that Selling price = [(100 + Gain%)/100] * CP= [(100 + 10)/100] * x

= [110/100] * x = 110x/100 = 11x/10

ATQ, it had been sold for ₹99 more

Selling price = ₹(11x/10) + 99 ——(1)

The gain would have been 12%

Selling Price = [(100 + Gain%)/100] * CP= (112/100) * x

= 112x/100 = ₹28x/25 ——(2)

On solving (1) & (2), we get

=> (28x/25) = (11x/10) + 99

=> (28x/25) – (11x/10) = 99

=> (56x – 55x) = 99 * 50

=> x = ₹4950

Therefore, the Cost Price of cycle = ₹4950

**12. A bucket was sold at a loss of 8%. Had it been sold for ₹56 more, there would have been a gain of 8%. What is the Cost Price of the bucket?**

**Solution:** Let the C.P. of bucket= ₹x

Loss= 8%

S.P. = [(100 – 8) * x]/100

S.P. = 92x/100

Now, it had been sold for ₹56 more

S.P.= (92x/100)+56

Gain% = 8%

S.P.= (100+8) * x/100

Difference between two S.P.’s= ₹56

=> (108x/100) – (92x/100)= 56

=> 16x = 56 * 100

=> x= (56 * 100)/16

=> x= 350

∴ Cost Price of the bucket is ₹350

**13. The selling price of 18 books is equal to the cost price of 21 books. Find the Gain Percent or Loss Percent?**

**Solution:** Given, S.P. of 18 Books = C.P. of 21 Books

Let the Cost Price of 21 books = a

Cost Price of 1 book = a/21

Selling Price of 18 book = a

Selling Price of 1 book = a/18

Gain on 1 book = S.P. – C.P. = a/18 – a/21 = (7a – 6a)/126 = a/126

Now, Gain% = (Gain on 1 book * 100) / C.P. of 1 book

= (a/126) * 100/( a/21) = 100 * 21/126 = 100/6 = 16.67 %

**14. The cost price of 12 fans is equal to the selling price of 16 fans. Find the Gain percent or Loss Percent?**

**Solution:** Given, C.P. of 12 fans = S.P. of 16 fans

Let the Cost Price of 12 fans = a

Cost Price of 1 fan = a/12

Selling Price of 16 fans = a

Selling Price of 1 fan = a/16

Loss on 1 fan = C.P. – S.P. = (a/12) – (a/16) = (4a – 3a)/48 = a/48

Loss% = (Loss/CP) * 100 = (a/48)/(a/12) * 100 = 100/4 = 25%

**15. On selling 250 cassettes, a man had gain equal to the selling price of 25 cassettes. Find the Gain Percent?**

**Solution:** Let S.P. of 1 Cassette= ₹100

S.P. of 25 Cassette= 100 * 25 = ₹2500

S.P. of 250 Cassette= 100 * 250 = ₹25000

C.P. of 250 Cassette= S.P. of 250 Cassette – Gain of 25 Cassette = 25000 – 2500 = ₹22500

Gain%= (2500/22500) * 100 = 11.11%

**17. Toffees are bought at 2 for a rupee and sold at 5 for ₹3. Find the Gain Percent or Loss Percent?**

**Solution:** Let C.P. of 2 Toffees= ₹1

C.P of 1 Toffee= ₹1/2

S.P of 5 Toffees= 3

S.P. of 1 Toffee= ₹3/5

Gain= S.P. – C.P. = (3/5) – (1/2) = 1/10

Gain%= (1/10)/(1/2) * 100 = 20%

**18. Coffee costing ₹450 per Kg was mixed with chicory costing ₹225 per Kg in the ratio of 5:2 for a certain blend. If the mixture was sold at ₹405 per Kg. Find the Gain Percent or Loss Percent?**

**Solution:** C.P. of 1 Kg coffee= ₹450

C.P. of 5 Kg coffee= 450 * 5 = ₹2250

C.P. of 1 Kg chicory= ₹225

C.P. of 2 Kg chicory= 225 * 2 = ₹430

Now, C.P. of (5+2) Kg mixture= 2250 + 450 = ₹2700

Now, S.P. of 1 Kg of mixture= ₹405

∴ S.P. of 7 Kg mixture= 405 * 7 = ₹2835

Gain = 2835 – 2700 = ₹135

Gain% = (135/2700) * 100 = 5%

∴ Loss%= {(73.50/490)*100)%= 15%

**21. A shopkeeper purchased a T.V. set for ₹2960 and spent ₹595 on its repairs and ₹120 on its transportation. He then sold it for ₹4557. Find his gain percent?**

**Solution:** C.P.= ₹2960

Overhead expenses= ₹(595+120)= ₹715

Actual C.P.= C.P. + Overhead expenses= ₹(2960+715)= ₹3675

S.P.= ₹4557

Since S.P.>C.P. so there is a Gain

Gain= S.P. – C.P.= ₹(4557-3675)= ₹882

∴ Gain%= {(882/3675)*10}%= 24%

**22. A man bought oranges at 8 for ₹34 and sold them at 12 for ₹57. Find his Gain or Loss Percent?**

**Solution:** C.P. of 8 oranges= ₹34

C.P. of 1 orange= ₹(34/8)

C.P. of 24 oranges= ₹{(34/8)*24}= ₹102

S.P. of 12 oranges= ₹57

S.P. of 1 orange= ₹(57/12)

S.P. of 24 oranges= ₹{(57/12)*24}= ₹114

Since S.P.>C.P. so there is a Gain

Gain= ₹(114-102)= ₹12

∴ Gain%= {(12/102)*100}%= 200/17%= 11.76%

**23. If the cost Price of 10 articles is equal to the selling price of 8 articles. Find the Gain or Loss Percent?**

**Solution:** Let the cost price of each article be ₹x. Then,

C.P. of 8 articles= ₹8x

S.P. of 8 articles= C.P. of 10 articles= ₹10x

Gain= ₹10x-8x= ₹2x

∴ Gain%= {(2x/8x)*100}%= 25%

**24. By selling 33 meters of cloth, One gains the selling price of 11 meters. Find the Gain percent?**

**Solution:** Given, Gain on selling 33m= (S.P. of 33m) – (C.P. of 33m)

=> S.P. of 11m= (S.P. of 33m) – (C.P. of 33m)

=> C.P. of 33m= (S.P. of 33m) – (S.P. of 11m)

=> C.P. of 33m= S.P. of 22m

Let the C.P. of each metre of cloth be ₹x. Then,

C.P. of 22m = ₹22x

S.P. of 22m= C.P. of 33m= ₹33x

Gain on 22m of cloth= S.P.- C.P. = ₹(33x-22x)= ₹11x

∴ Gain%= {(11x/22x)*100}= 50%

**25. A T.V. set was sold at a gain of 15%. Had it been sold for ₹575 more, the gain would have been 20%. Find the cost price of the set?**

**Solution:** Let the cost price if the T.V. set be ₹x

When the gain is 15%, the S.P.= ₹(x+15% of x)= ₹23x/20

When the gain is 20%, then S.P.= ₹(x+20% of x)= ₹6x/5

Now, the difference between the two S.P.’s= ₹575

ATQ, (6x/5) – (23x/20)= 575

x= 11500

∴ The cost price of the set is ₹11500

**5. A grocer purchase 80 Kg of rice at ₹27 per Kg and mixed it with 120 Kg of rice purchased at ₹32 per Kg. At what rate per Kg should he sell the mixture to gain 16%?**

**Solution:** C.P. of 80 kg rice at ₹27 per kg= 27*80= ₹2160

C.P. of 120 kg rice at ₹32 per kg= 32*120= ₹3840

So, C.P of (80+120=200)kg rice= 2160+3840= ₹6000

Gain%= 16%

∴ S.P. of 200 kg rice= (100+16)/100*6000= ₹6960

Also S.P. of 1 kg rice= 3480/100= ₹34.80 per kg

**6. Mrs. Harjeet bought two bags for ₹1,150 each. She sold one of them at a gain of 6% and the other at a loss of 2%. How much did she gain?**

**Solution:** C.P of each bag= ₹1150

C.P. pf 2 bags= 1150*2= ₹2300

Now C.P. of first bag= ₹1150

Gain%= 6%

S.P.= (100+6)/100*1150= ₹1219

Now C.P. of second bag= ₹1150

Loss= 2%

S.P. = (100-2)/100*1150= ₹1127

S.P. of 2 bags= 1219+1127= ₹2346

∴ Gain= 2346-2300= ₹46

**7. A trader purchased a wall clock and a watch for a sum of ₹5,070. He sold them making a profit of 10% on the wall clock and 15% on the watch. He earns a profit of ₹669.50. Find the cost price of the wall clock and that of the watch?**

**Solution:** Let C.P. = x

Gain = 10%

S.P.= (100+Gain%)/100*C.P.= (100+10)/100*x= ₹11x/10

Gain= (11x/10)-x= x/10

C.P.= (5070-x)

Gain= 15%

S.P.= (100+15)/100*(5070-x)

Gain= (23/20)*(5070-x) – (5070-x)= (3/20)*(5070-x)

Total Gain= x/10 + (3/20)*(5070-x) = (15210-x)/20

Given Profit= ₹669.50

Cost of washing machine after discount= (25000-3000) = ₹22000

(i) Tax= 10% of ₹22000= ₹2200

(ii) Final Price= (22000+2200) = ₹24200

**18. Reena purchased a face cream for ₹113.40 including tax. If the printed price of the face cream is ₹105, find the rate of tax on it?**

**Solution:** Price of face cream= ₹113.40

Printed price= ₹105

Tax= (113.40 – 105) = ₹8.40

Tax on ₹105 = ₹8.40

Rate of Tax= 8.40/105 * 100 = 8%

**19. Vivek purchased a laptop for ₹34,164, which includes a 10% rebate on the marked price and then a 4% tax on the remaining price. Find the marked price of the laptop?**

**Solution:** C.P. of laptop= ₹34164

Rebate= 10%

Rate of tax= 4%

Let M.P. = ₹x

S.P.= (100-10)/100*x = 9x/10

Tax= 4% of 9x/10 = 9x/250

C.P. = (9x/10) + (9x/250) = 234x/250

ATQ, 234x/250 = 34164

x= ₹36500

∴ The marked price of the laptop is ₹36500

**20. Tanya buys an electric iron for ₹712.80, which includes two successive discounts of 10% and 4% respectively on the marked price and then 10% tax on the remaining price. Find the marked price of the electric iron?**

**Solution:** Let the price of iron= ₹x

First discount= 10%

C.P. after discount= (100-10)/100*x= 9x/10

Second discount= 4%

C.P. after discount= (100-4)/100* (9x/10)= 864x/1000

Rate of tax= 10%

∴ Total Tax= 10% of (864x/1000)= 864x/10000

Total C.P.= (864x/1000) + (864x/10000) = 9504x/10000

ATQ, (9504x/10000) = 71280/100

x= ₹750

Marked Price of the electric iron= ₹750

**21. The price of a food processor inclusive of a tax of 5% is ₹6,930. If the tax is increased to 8%, how much more does the customer pay for it?**

**Solution:** Let the price of a food processor= ₹x

Tax= 5% of x = 5x/100

Total cost= x+(5x/100) = 105x/100

ATQ, 105x/100 = 6930

x= ₹6600

If marked price of food processor= ₹6600

Tax at new rate= 8% of 6600= ₹528

Price to be paid= 6600+528= ₹7128

Increase in last amount= 7128-6930= ₹198

The customer has to pay ₹198 more

**22. The price of a laser printer including 7% tax is ₹17,334. How much less does a customer pay for it, if the tax on it is reduced to 4%?**

**Solution:** Let the price of laser printer= ₹x

Tax= 7% of x = 7x/100

Total cost of printer= x + (7x/100)= 107x/100

ATQ, 107x/100=17334

x= ₹16200

Now M.P. of laser printer= ₹16200

New reduced Tax= 4% of 16200= ₹648

C.P. = 16200+648= 16848

Reduced price= 17334-16848= ₹486

Hence the customer has to pay ₹486 less

**Extra**

**23. The marked price of a ceiling fan is ₹1750 and the shopkeeper allows a discount of 6% on it. Find its selling price?**

**Solution:** Marked Price= ₹1750 and Discount= 6%

∴ Discount= 6% of M.P. = 6% of 1750= ₹105

∴ S.P. of the fan= M.P. – S.P.= ₹(1750-105)= ₹1645

Hence the selling price of the fan is ₹1645

**24. An article marked at ₹587.50 is sold for ₹517. Find the rate of discount offered?**

**Solution:** M.P.= ₹587.50 S.P.= 517

Discount given= M.P. – S.P.= ₹(587.50-517)= ₹70.50

∴ Rate of discount= (70.50/587.50)*100= 12%

Hence a discount of 12% was offered

**25. A trader marks his goods 40% above the cost price and allows a discount of 25%. What gain% does he make?**

**Solution:** Let the cost price of any of his goods be ₹100

Then, its marked price= ₹140

Discount= 25% of 140= ₹35

∴ Selling Price= M.P. – Discount= ₹(140-35)= ₹105

Gain= Selling Price- Cost Price= ₹(105-100)= ₹5

∴ On a cost price of ₹100, Gain= ₹5

And so, gain%= 5%

Hence the trader gains 5%

**26. A dealer allows a discount of 25% to his customers and still gains 25%. Find the marked price of an article that costs the dealer ₹1080?**

**Solution:** C.P. = ₹1080 and Gain= 25%

∴ S.P. = {(100+25)/100}*1080= ₹1350

Let the marked price be ₹x

∴ Discount allowed= 25% of ₹x= ₹x/4

S.P.= M.P. – Discount= x-(x/4)= ₹3x/4

Now, 3x/4= 1350

x= ₹1800

Hence the marked price of the article is ₹1800

**27. After allowing a discount of 10% on the marked price of an article a dealer gains 8%. By what percent is the marked price above cost price?**

**Solution:** Let the marked price of the article be ₹x

Then discount allowed= 10% of ₹x= ₹(10/100) * x= ₹x/10

∴ Selling price of the article= M.P. – Discount= ₹x-(x/10)= ₹9x/10

Now, Gain%= 8%

∴ C.P. = {100/(100+8)}*(9x/10)= ₹5x/6

Difference between M.P. and C.P.= ₹x-5x/6= ₹x/6

∴ The M.P. is above C.P. by= {(x/6)/(5x/6)}*100= 20%

Hence the marked price is above the cost price by 20%

**28. Find the single discount equivalent to two successive discounts of 20% and 5%?**

**Solution:** Let the marked price of an article be ₹100

Discount given on it= 20% of 100= ₹20

Reduced price after first discount= ₹(100-20)= ₹80

Next discount= 5% of 80= ₹4

Price after second discount= ₹(80-4) =₹76

∴ S.P. of the article= ₹76

Net discount= M.P. – S.P.= ₹(100-76)= ₹24

Thus net discount on M.P. of ₹100 is ₹24

∴ Single discount equivalent to given successive discounts= 24%

**29. A dealer quotes the price of a suitcase as ₹675 and charges tax at a rate of 8%. Find the amount that a customer has to pay for the suitcase?**

**30. Abhay bought a mobile phone listed at ₹2800. If he got a discount of 15/2% on it and paid tax at the rate of 10%, find the final amount he paid for the phone?**

**Solution:** List price of the mobile phone= ₹2800

Discount= 15/2% of 2800= ₹210

Sale price of the movie phone= ₹(2800-210)= ₹2590

Tax= 10% of ₹2590= ₹259

∴ Total amount paid by Abhay= ₹(2590+259)= ₹2849

**31. The price of a television set, inclusive of tax is ₹13530. If the rate of tax is 10%, find (i) Its basic price (ii) Amount of tax**

**Solution:**

(i) Let the basic price of the television be ₹x

Tax= 10% of ₹x= ₹x/10

Total price of the television= ₹x+(x/10)= ₹11x/10

∴ 11x/10= 13530

x= ₹12300

Hence the basic price of the television is ₹12,300

(ii) Amount of tax= 10% of ₹12300 = ₹(10/100)*12300= ₹1230

**32. Sachin purchased a bat for ₹1458 which includes a 10% discount on the marked price and then 8% tax on the remaining price. Find the marked price of the bat?**

Price of the bat after discount= ₹x-(x/10)= ₹9x/10

Tax= 8% of 9x/10= ₹9x/125

Price to be paid= ₹(9x/10)+(9x/125)= ₹243x/250

∴ 243x/250 = 1458

x= ₹1500

Hence, the marked price of the bat is ₹1500.
