• A. Rs 2 loss
• B. Rs 2 profit
• C. Rs 7 loss

Answer 1

The correct option is D No profit no loss.

$20㎏$ wheat$⟶$Rs. $9.5$ per $㎏$

$30㎏$ wheat $⟶$ Rs. $8.50$ per $㎏$

Total cost price=Rs. $(20\times 9.5+30\times 8.5)$

=Rs. $(190+255)=$ Rs. $445$

Selling rate=Rs. $8.9$ per $㎏$

$\therefore$ Total sellig price=Rs. $8.9\times 50㎏$

=Rs. $445$

$\because$SP=CP

$\therefore$No loss or profit
