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

Answer 1

The correct option is A

₹ $96$ and $5.08kg$

Cost of $6kg$ of wheat = ₹ $72$

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

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

Quantity of wheat that can be purchased in ₹ $1$ = $\frac{6}{12}$

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