Question

number of toys sold was decreased by 15%. What was
the effect on the sales of the shop ?
a) 4% increased
b) 4% decreased
c) 2% increased
d) 2% decreased​

Answer 1

Answer:

The answer is option (C): 2% increased.

Step-by-step explanation:

Let the original price of each toy be Rs. 100 and number originally sold be 100.

Since the originally sale proceeds = Rs. (100 x 100) = Rs. 10000

New sale proceeds = Rs. (120 x 85) = Rs. 10200

Increase in percentage  = (200 x 100 / 10000)% = 2%

Thus the increase in percentage is 2%.
