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 with 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 with Rs. 72 = 6 kg

Quantity of wheat that can be purchased with Rs. 1 = $\frac{6}{72}$

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