Question

The cost of 15 apples is equals to the selling price of 12 apples. find the profit percent?
​

Answer 1

Let the cost price of 10 apples be ₹ x

Then, selling price of 12 apples ( SP) = ₹ x (given)

Cost price of 12 apples (CP)= x * 12 / 10 = 1.2 x

% Loss =

(CP of 12 apples - SP of 12 apples) * 100 / CP of 12 apples.

So, % loss = (1.2 x - x ) * 100 / 1.2 x

= 0.2 x * 100 / 1.2 x = 20 / 1.2 = 16.67 %
