When the price of a speaker was decreased by 10%, the number sold increased by 15%. What was the effect on the total revenue?

3.5%

2.5%

7.5%

Explanation:

Let the price of the speaker be Rs. 100
and let the original sale be 100 pieces.
Then, total revenue = Rs. (100x100) = Rs. 10000
New revenue = Rs. (90x115) = Rs. 10350
Increase in profit = 10350-10000 = Rs. 350
Increase in revenue = (350/10000) 100 % = 3.5%
