Sanket purchased 20 dozen notebooks at Rs 48 per dozen. He sold 8 dozen at 10% profit and the remaining 12 dozen with 20% profit. What is his profit percentage in the transaction?
20 dozen notebooks at Rs 48 per dozen
Total cost = 20 $$\times$$ 48 = 960
He sold 8 dozen at 10% profit
$$\therefore$$ Profit from 8 dozen = 8 $$\times$$ 48 $$\times$$ 0.1 = 38.4
He sold 12 dozen at 20% profit
$$\therefore$$ Profit from 12 dozen = 12 $$\times$$ 48 $$\times$$ 0.2 = 115.2
Total Profit = 38.4 + 115. 2= 153.6
Profit percentage = 153.6/960 $$\times$$ 100 = 16%
Hence, option B is the correct choice.
