Question

Cost of 5 kg of wheat is Rs 91.50.

(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) Cost of 5 kg wheat = Rs 91.50

Cost of 1 kg wheat = $\frac{91.50}{5}=\mathrm{Rs}18.30$

Therefore, cost of 8 kg wheat = 18.30 × 8 = Rs 146.40

(b) Wheat purchased in Rs 91.50 = 5 kg

Wheat purchased in Re 1 = $\frac{5}{91.50}$kg

Therefore, wheat purchased in Rs 183 = $\frac{5}{91.50}\times 183$ = 10 kg
