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

Answer 1

The correct option is A Rs $96$ and $5.08kg$

Cost of $6kg$ of wheat = Rs $72$

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

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

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

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