• C. $53$
• D. $33$

Answer 1

The correct option is A $35$

$5$ person maintained for $20$ days with Rs. $2,480.$

Then, $1$ person maintained at $\frac{2480}{20\times 5}=\frac{2480}{100}$$=$Rs. $24.80$ /person/day

So, the maintenance of $8$ persons $=24.80\times 8=198.40$ /day.

So, the number of days Rs $6944$ can be maintained $8$ person will be

$\frac{6944}{198.40}=35$ days
