Question

If $12$ men complete a work in $20$ days. If only $8$ men are employed, then the time required to complete the same work is

• A. $24$ days
• B. $25$ days
• C. $30$ days
• D. $35$ days

Answer 1

The correct option is C $30$ days

As $12$ men complete work in $20$ days, $1$ man will complete the same work in

$20\times 12=240$ days.

Time required by $8$ men to complete the work=$\frac{240}{8}$=$30$ days..
