Question

Cost of $6kg$ of wheat is Rs $72$. What will be the cost of $1kg$ 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 $6kg$ of wheat is Rs $72$, the cost of $1kg$ will simply be Rs $72$ divided into $6$ parts. So we have,
Cost of $1kg$ = $72/6$ = Rs $12$
