Correct Answer - Option 4 :
\(Loss,4\frac{{16}}{{21}}\)
Given:
Cost price each egg = Rs.1.40
Selling price each egg = Rs.1.60
Formula used:
Loss = Cost price - Selling price
Loss percent = Loss/Cost price × 100
Calculation:
Cost price of 40 dozen eggs = 12 × 40 × 1.40 = 672
Cost price of 80 eggs = 80 × 1.40 = 112
Cost price of 400 eggs = 400 × 1.40 = 560
Selling price of the remaining (480 - 80) eggs = 400 × 1.60 = 640
Loss = Cost price - Selling price
Cost price of 40 eggs that were broken in transportation will be treated as a loss.
Loss = (560 + 112) - 640 = 32
Loss percent = 32/672 × 100 = \(4\frac{{16}}{{21}}\)%
∴ The required loss percent is \(4\frac{{16}}{{21}}\)%
