• If cost of 15 eggs is Rs.75, then find out the cost of 4 dozens eggs.
 A) Rs.240 B) Rs.300 C) Rs.150 D) Rs.185

 A) Rs.240

Because, Cost of 15 eggs = Rs.75

Therefore, Cost of 1 egg = $$\Large \frac{75}{15}$$

Cost of 4 dozens $$\Large 4 \times 12 = 48$$ eggs

= $$\Large \frac{75}{15} \times 48$$ = Rs.240
