A shopkeeper purchased 120 pears for ₹15 each. However, 10 pears were rotten and thrown away. The remaining sold at ₹18 each. What will be the percentage profit?

10%

Cost of 1 pear = 15

Cost of 120 pears = 120 × 15 = 1800

10 are rotten and thrown away then, 

SP of 1 pear = 18

SP of 120 pears = 110 × 18 = Rs. 1980

Hence, Profit = 1980 – 1800 = 180

Profit percentage = \(\frac{180}{1800}\) × 100 = 10%
