• A. Rs $130$
• B. Rs $140$
• C. Rs $160$
• D. Rs $180$

Answer 1

The correct option is B Rs $140$

$\because \frac{3}{5}$ quintal of wheat costs Rs $210$

$1$ quintal of wheat costs Rs.

$=\frac{210}{\left(\frac{3}{5}\right)}=350$

$\therefore 0.4$ quintal of wheat costs $=350\times 0.4=$ Rs. $140$.
