Cost price of 12 lemons = ₹25
Then, cost price of 1 lemon = ₹ (25/12)
Cost price of 5 lemons = (25/12) × 5
= 125/12
= ₹ 10.42
He sold 5 lemons for = ₹12 =Selling price
By comparing SP and CP = SP > CP, so there is a gain
Gain = SP – CP
= 12 – 10.42
= ₹ 1.58
Gain % = {(gain/CP) × 100}
= {(1.58/10.42) × 100}
= {15800/1042}
= 15.2%
