A shopkeeper bought 40 dozen eggs at ₹1.40 each. 80 eggs were broken in transportation. He sold the remaining eggs at ₹1.60 each, What is his profit or loss per cent?

Loss, $4\frac{16}{21}$

Cost price each egg = Rs.1.40 

Selling price each egg = Rs.1.60 

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 80 eggs that were broken in transportation will be treated as a loss. 

Loss = (560 + 112) - 640 = 32

Loss percent = \(\frac{32}{672}\) × 100 = Loss, $4\frac{16}{21}$
