Question

Cost of 5 kg of wheat is  91.50 Rs.
(a) What will be the cost of 8 kg of wheat?
(b) What quantity of wheat can be purchased in Rs.183?

Answer 1

(a) According to the given problem,

The cost of 5 kg of wheat = ₹ 91.50.

Now, the cost of 1 kg of wheat will be 91.50 / 5 = ₹ 18.3

Therefore, the cost of 8 kg of wheat is 18.3 × 8

= ₹ 146.40

(b) Let us calculate the quantity of wheat purchased in ₹183

Quantity of wheat purchased in ₹ 91.50 = 5 kg

Hence, wheat purchased in ₹ 1 = 5 / 91.50 kg

Therefore, wheat purchased in ₹ 183 = (5 / 91.50) × 183

= 10 kg

Thus, we can say that the cost of 8 kg of wheat is ₹ 146.40, and the quantity of wheat purchased in ₹ 183 = 10 kg.
