Question

by selling 36 bananas Avenger lost the selling price of 4 bananas find his loss percent

Answer 1

If x is the price of 1 banana then, 
Let the selling price (S.P) of 36 bananas be 36x, 
The loss will be 4x, 
Loss percent=loss/cost price x 100 
=loss/(selling price +loss) × 100 
=4x/(36x+4x) × 100 
=4x/40x × 100 
=1/40 × 100 
=10%
