Hari purchased 20 dozen notebook at Rs. 48 per dozen. He sold 8 dozen at 10% profit and remaining 12 dozen with 20% profit. What is his profit percentage in the transaction?
CP of 20 dozen = Rs. (48 x 20) = Rs.960
CP of 8 dozen = Rs. (48 x 8) = Rs. 384.
CP of 12 dozen =Rs. (960 384) = Rs. 576
Total S.P = Rs. (110/100 x 384 +120/100 x 576) = Rs.1113.60
Profit % = (153.60/960 x 100) % =16%.
