Answer 1

suppose the cost price of each orange is x.then the cost price of 20 Oranges is 20x.similarly the selling price of 16 oranges is 20x.the selling price of each orange is 20x÷16.the net profit per each orange is (20x÷16)-x=(x÷4)...
the percentage of profit is 25%.

Answer 2

Let cp of 1 orange be rs. 1
Cp of 20 orange be rs. 20
Sp of 16 orange =rs. 20
Sp of 1 orange =rs. 20/16
Sp of 20 orange =rs20/16*20
=rs. 25

Profit=sp-cp
=25-20
=rs. 5
Profit%=profit*100/cp
5*100/20
=25%
