840750720940500Option C

By applying alligation method,

20% 10%

13.5%

3.5 6.5

ratio = 7 : 13

CP of math book = 2400*7/20 = 840

CP of English book = 2400*13/20 = 1560

Difference = 1560 – 840 = 720 - The cost price of an article is rs.400 and marked price of an article is rs.480. If there are 15% discount is given on marked price, then what is profit percentage occurred by selling it ?
4%18%8%2%20%Option D

CP of article = 400

MP of article = 480

Discount = 480 * 15/100 = 72

SP of article = 480 – 72 = 408

profit % = 408 – 400/400 * 100 = 2% - A man purchased two articles for rs.1250 each. He sold one at 20% profit and the other is 30% loss find the overall profit or loss percentage ?
17% loss8% loss5% profit5% loss14% profitOption D

CP of one article = 1250

SP = 1250 * 120/100 = 1500

CP of other article = 1250

SP = 1250 * 7/10 = 875

Total CP = 1250 + 1250 = 2500

total SP = 1500 + 875 = 2375

Loss % = 125/2500 * 100 = 5% - The cost price of 10 books is equal to the selling price of 8 books. What is the profit percentage ?
28%23%25%22%20%Option C

Let the CP of a one book = 10x

CP of 10 book = 100x

SP of 8 book = 100x

CP of 8 book = 80x

profit % = 100x – 80x/80x * 100 = 25% - The profit obtained by selling of the product for rs.500 is same as the loss when it sold for rs.350. What is the cost price of the product ?
500475625425355Option D

Let CP of the product = x

SP = 500

profit = 500 – x

SP = 350

loss = x – 350

500 – x = x – 350

2x = 850

x = 425 - If a table is sold at gain of 15% instead at a gain of 8%, then the seller gets rs.84 more. What is cost price of that table ?
12501340120014801400Option C

Let CP of table = 100x

when it sold at 8% profit, SP of table = 108x

When is sold at 15% profit, SP of table = 115x

115x – 108x = 84

7x = 84

x = 12

cost price of table = 100x = 100 * 12 = 1200 - A man sells an item for rs.600 and make some profit. If he sells it for rs.390 his loss is 2/5th of earlier profit. What is the cost price of the item ?
425550750450645Option D

Let CP of item = x

If he sells for rs.600

profit = 600 – x

If he sells for rs.390

loss = x – 390

(600 – x)2/5 = x – 390

1200 – 2x = 5x – 1950

7x = 3150

x = 450 - Sinu sold an item for rs.7200 and he incurred a loss of 20%. At what price should he have sold an item so that to have gained a profit of 18% ?
126408740106209451450Option C

SP of an item = 7200

loss = 20%

CP = 7200 * 5/4 = 9000

when he sold at profit of 18%

SP = 9000 * 118/100 = 10620 - The marked price of the mouse is 25% more than the cost price and when it sold profit earned by shopkeeper is 12.5%. If the marked price of the mouse is rs.750, then how much amount of discount is given when it sold ?
8082847568Option D

MP of the mouse = 750

CP of mouse = 750/5 * 4 = 600

SP = 600 * 112.5/100 = 675

discount = 750 – 675 = 75 - A sold an article to B at a profit of 20% and B sells it to C at a loss of 40% and C paid for rs.1440. What is the selling price for which A sold ?
46002400340022001400Option B

Let CP of an article for A = 100x

SP for A = 120x

CP for B = 120x

SP for B = 120*3/5 = 72x

C pays = 1440

72x = 1440

x = 20

SP for A = 120*20 = 2400
