a) What will be the cost of $6kg$ of wheat?

b) What quantity of wheat can be purchased in Rs $94.5$?

• A. Rs $54$ and $10.5kg$
• 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 $54$ and $10.5kg$

Cost of $8kg$ of wheat = Rs $72$

Cost of $1kg$ of wheat = $72/8$ = Rs $9$

Cost of $6kg$ of wheat = $9\times 6$ = Rs $54$

Quantity of wheat that can be purchased in Rs $1$ = $8/72$

Quantity of wheat that can be purchased in Rs $94.5$ = $8/72\times 94.5$ = $10.5kg$
