Question

The cost of a crate of 30 eggs is Rs. 120. Find the cost of one - fifth of the crate. [ 3 marks ]

Answer 1

Cost of 30 eggs = Rs.120
Cost of 1 egg = $120÷\mathrm{30\; [\; 1\; marks\; ]}$
= Rs. 4
Number of eggs in one fifth crate = $\frac{1}{5}\times \mathrm{30\; [\; 1\; marks\; ]}$
= 6 eggs
Cost of 6 eggs = $6\times 4$
= Rs.24 [ 1 marks ]
