Question

If $10$ men take $6$ days to construct a garage, how many more men are needed if the garage is constructed in $5$ days?

Answer 1

Given that $10$ men takes $6$ days to construct a garage.

Assume $x$ men are needed if the garage is constructed in $5$ days.

Since same garage is now to be constructed in less days, number of men required will be more.

Number of men required to construct garage in $1$ day $=$$10\times 6=60$

Number of men required to construct garage in $5$ days $=$$\frac{60}{5}=12$

Number of men more needed $=$$12-10=2$

Hence, $2$ more men are needed if the garage is constructed in $5$ days.
