Question 45

When 5 percent is lost in grinding wheat, a country has to import 20 million bags to make up of the loss. But when only 2 percent is lost, it has to import 15 million bags. What is the quantity of wheat which grows in the country in million bags?

Solution

Given, when 5 percent is lost in grinding wheat, the country has to import 20 million bags to make up of the loss,

5% of wheat = 20 million bags ......(1)

When only 2 percent is lost, it has to import 15 million bags,

2% of wheat = 15 million bags ......(2)

From equation (1) and (2)

3% of wheat = 5 million and 100% = $$\frac{500}{3} = 166 \frac{2}{3}$$

Hence, option D is the correct answer.
