Question

Cost of 6 kg of wheat is Rs 72. What will be the cost of 1 kg of wheat?

• A. Rs 12
• B. Rs 432
• C. Rs 78
• D. Rs 96

Answer 1

The correct option is A

Rs 12

This is a classic case of the simple unitary method. If the cost of 6 kg of wheat is Rs 72, the cost of 1 kg will simply be Rs 72 divided into 6 parts. So we have,
Cost of 1 kg = $\frac{72}{6}$ = Rs 12
