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

Answer 1

The correct option is A ₹96 and 5.08 kg

Cost of 6 kg of wheat = ₹72

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

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

Quantity of wheat that can be purchased with ₹72 = 6 kg

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

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