Ritu purchased (5 / 2) dozen eggs at the rate of Rs. 20 per dozen. She found that 6 eggs were rotten. She sold the remaining eggs at the rate of Rs. 22 per dozen. Then her profit or loss per cent is :
-
- 12% loss
- 12% profit
- 10% loss
- 10% profit
Correct Option: A
Given that ,
| C.P. of 2 | dozen eggs = 30 eggs | 2 |
| C.P. of 30 eggs = | × 30 = Rs. 50 | 12 |
Their S.P i.e. S.P. of 24 eggs = 22 × 2 = Rs. 44
∴ Loss = C.P. - S.P. = Rs. (50 – 44) = Rs. 6
| ∴ Loss percent = | × 100 | |
| C.P. |
| ∴ Loss % = | × 100 = 12% | 50 |
