Question

Mark the correct alternative in the following question:

6 dozen eggs are bought for ₹108. How much will 108 eggs cost?

(a) ₹171 (b) ₹162 (c) ₹153 (d) ₹180

Answer 1

As, the cost of 6 dozen eggs (6 × 12 = 72 eggs) = ₹108

⇒ The cost of 1 egg = $\frac{108}{72}=\frac{3}{2}$

So, the cost of 108 eggs = $\frac{3}{2}\times 108=3\times 54$ = ₹162

Hence, the correct alternative is option (b).
