# profit and loss tricks

WORKED – OUT PROBLEMS

1. An article is sold for Rs. 4600 at a gain of 15%. What would be the profit or loss percent if it is sold for Rs. 3600 ?

Solution: C.P.  = 100/115 × 4600

= 4000

If S.P.  = 3600, then

loss %    = 400/4000 × 100

= 10%

2. A man sold his car at a loss of 5%. Had he sold it for Rs. 18000 more, he would have made a profit of 4%. Find the cost price of the car.

Solution: initial S.P. is at 5% loss

New S.P. is at 4% profit

The difference in the two S.P. = 9% of C.P.

9% of C.P. = 18000

C.P. = 18000 × 100/9

= Rs. 200000

3. By selling two articles, a man gains Rs. 3750 on the whole. He sells one article for Rs.

69000 at 15% profit. Find the cost price of the other article if it is sold at 20% loss.

Solution: profit = 69000 × 15/115

= 9000

To gain on whole, he must have a loss of 9000 – 3750 = 5250 on the other article

20% of C.P. = 5250
C.P. = 5250 × 5
= 26250

4. Two brands of tea costing Rs. 850 and Rs. 950 per kg respectively are mixed in the ratio 3:5 by weight. If one-fourth of the mixture is sold at Rs. 1100 per kg and the remaining at the rate of Rs. 1200 per kg, find the profit percent on the whole

Solution: let 3 kg of Rs. 850 per kg and 5 kg of 950 per kg be mixed together.
C.P. of the mixture = 3850 + 5950

= 7300

one -fourth of 8 kg  = 2 kg

Remaining mixture = 6 kg

S.P. of the mixture  = 2 × 1100 + 6 × 1200
= 9400

profit % = 2100/7300 × 100

= 28.77%

5. A man sells an article at 5% above its cost price . if he had bought it at 5% less than what he paid for it and sold for it for Rs. 2 less, he would have gained 10% . find the cost price of the article.

Solution:  let C.P. = 100

Then S.P. = 105

If new C.P. = 95

And new S.P. with 10%  profit = 104.5

Then the difference in S.P. = .5

When the difference is 2, then C.P. = 100×2/.5

= 400

6. S.P. of 20 identical pens is equal to the C.P. of 15 identical pens. Find the % profit or % loss.

Solution: let S.P. of 20 pens = 100
S.P. of 15 pens = 75

C.P. of 15 pens = 100

7. A man buys an article whose marked price is Rs.800 and available at two successive discounts 25% and 15%. He tagged new M.P. on the article and give 10% discount further and want to sold at a 20% profit. Find the new M.P. of the article.

Solution: C.P. of article for a man = 800 × 75/100 × 85/100

= 510

S.P. of the article for a man = 510 × 120/100

= 612

New M.P. = 612 × 100/90

= 680

8. The profit earned after selling an article for Rs. 1516 is the same as loss incurred after selling the article for Rs. 1112. What is the cost price of the article ?

Solution: let profit = loss = x

1516 – x = 1112 + x

1516 – 1112 = 2x

2x = 404

x = 404/2

x = 202

C.P. = 1112+202

= 1314

10. A man sold a wristwatch for Rs. 2400 at a loss of 25%. At what rate should he have sold the wristwatch to earn a profit of 25% ?

Solution: C.P. = 2400 × 100/75

= 3200

New S.P.  = 3200 × 125/100

= 4000

11. What is a single discount equivalent to three successive discounts 20%,10% and 15% ?

Solution: let marked price be 100

Then, S.P. = 100 × 80/100 × 90/100 × 85/100

= 61.2

Equivalent single discount  = 100 – 61.2

= 38.8%
