Question

Cost of 6 kg of wheat is Rs 72.

a) What will be the cost of 8 kg of wheat?

b) What quantity of wheat can be purchased in Rs 61?

• A. Rs 96 and 5.08 kg
• B. Rs 12 and 30.5 kg
• C. Rs 84 and 12 kg
• D. Rs 108 and 5.48 kg

Answer 1

The correct option is A

Rs 96 and 5.08 kg

Cost of 6 kg of wheat = Rs 72

Cost of 1 kg of wheat = $\frac{72}{6}$ = Rs 12

Cost of 8 kg of wheat = $12\times 8$ = Rs 96

Quantity of wheat that can be purchased in Rs 1 = $\frac{6}{12}$

Quantity of wheat that can be purchased in Rs 61 = $\frac{6}{72}\times 61$ = 5.08 kg
