| Lekhraj purchased 20 dozen apple at Rs. 48 per dozen. He sold 8 dozen at 10% profit and the remaining 12 dozen at 20% profit. What is the profit percentage in this whole transaction?

A. 18%

B. 16%

C. 20%

D. 12%

### Right Answer is: B

#### SOLUTION

Profit earned at 10% profit = 8 x 48 x 10/100 = Rs. 38.40

Profit earned at 20% profit = 12 x 48 x 20/100 = Rs. 115.20

Total profit earned = Rs. 38.40 + Rs. 115.20 = Rs. 153.60

Overall profit % = = 16%

**Alternative approach:**

Using alligation :

10 20

x

20-x x-10

Now (20-x)/(x-10) = 8/12 = 2/3

5x = 80

x= 16%
