Nalini purchased 20 dozen of apples at t48 per dozen. She sold 8 dozen of them at 10% profit and the remaining 12 dozen at 20% profit. What is the overall profit percentage gained in this transaction?
Answer & explanation
Correct answer: option 3
C.P of 20 dozen = Rs.(48 x 20) = Rs.960
C.P of 8 dozen = Rs. (48 x8) = Rs. 384.
C.P of 12 dozen =Rs. (960 – 384) = Rs. 576
Total S.P = Rs. (\(\frac{110}{100}\) x 384 + \(\frac{120}{100}\) x 576) = Rs.1113.60
∴ Profit % = (\(\frac{153.6}{960}\) x 100)% = 16%
