When the price of a toy was increased by 20%, the number of toys sold was decreased by 15%. What was the effect on the sales of the shop?
Correct Answer: 2% increased
Explanation:
Let original of each toy be Rs. 100 and number originally sold be 100.
∴ originaly sale proceeds = Rs. (100 x 100) = Rs. 10000 New sale proceeds = Rs. (120 x 85) = Rs. 10200
∴ Increase% = (200 x 100 / 10000)% = 2%
