Question

If $35$ men can reap a field in $8$ days, in how many days can $20$ men reap the same field?

• A. $16$
• B. $20$
• C. $14$
• D. $18$

Answer 1

The correct option is C $14$

$35$ men can reap the field in $8$ days, $1$ man can reap the field in $(35\times 8)$ days

[Fewer men, more days]
$20$ men can reap the field in $\frac{(35\times 8)}{20}$ days $=14$ days

[More men, fewer days]
Hence, $20$ men can reap the field in $14$ days.
