Question 1
In a certain store, the profit is 320% of the cost. If the cost increases by 25% but the selling price remains constant, approximately what percentage of the selling price is the profit?

A
30%
B
70%
C
100%
D
250%
Correct Answer: Option B

Let C.P.= Rs. 100. Then, Profit = Rs. 320, S.P. = Rs. 420.

New C.P. = 125% of Rs. 100 = Rs. 125

New S.P. = Rs. 420.

Profit = Rs. (420 - 125) = Rs. 295.

Required percentage = 295 x 100 % = 1475 %
420 21

= 70% (approximately).

Question 2
The percentage profit earned by selling an article for ₹1920 is equal to the percentage loss incurred by selling the same article for ₹1280. At what price should the article be sold to make 25% profit?

A
₹ 2000
B
₹ 2200
C
₹ 2400
D
Data inadequate
Correct Answer: Option A

Let C.P. be ₹ x.

Then, 1920 - x x 100 = x - 1280 x 100
x x

1920 - x = x - 1280

2x = 3200

x = 1600

Required S.P. = 125% of ₹ 1600

= ₹ 125 x 1600 = ₹ 2000.

B
4.5
C

12

Selling Price of 1 toy = ₹33

Profit % = 1.75 x 100 % = 28 % = 5.6%
31.25 5

Question 5
Alfred buys an old scooter for ₹ 4700 and spends ₹ 800 on its repairs. If he sells the scooter for ₹ 5800, his gain percent is:

A
4(4/7)%
B
5(5/11)%
C
10%
D
12%
Correct Answer: Option B

Cost Price (C.P.) = ₹ (4700 + 800) = ₹ 5500.

Selling Price (S.P.) = ₹ 5800.

Gain = (S.P.) - (C.P.) = ₹ (5800 - 5500) = ₹ 300.

Gain % = 300 x 100 % = 5 5 %
5500 11

A
15
B

C
18
D

Correct Answer: Option B

Let C.P. of each article be Re. 1 C.P. of x articles = ₹ x.

S.P. of x articles = ₹ 20.

Profit = ₹ (20 - x).

20 - x x 100 = 25
x

2000 - 100x = 25x

125x = 2000

x = 16.

S.P. of 56 kg rice = ₹ (56 x 30) = ₹ 1680.

Gain = 80 x 100 % = 5%.
