Question

C. The cost price of 12 bananas is equal to the SP of 15 bananas.Find loss or gain percent.​

Answer 1

20% loss.

Explanation:

Suppose the cost of each banana is $1

Then cost of 12 = $12.

You sell 15 bananas for $12, therefore the price of each banana is 12/15

= $0.80.

So the loss percent is (1 - 0.80) * 100

= 20%.
