Question

If 20 men can construct a housinh unit in 60 days. How many men are required to construct such housing unit in 48 days?

Answer 1

Answer:

25 mens

Step-by-step explanation:

Step 1 of 2:

mens:        days:

20 men = 60 days

$x$ men    = 48 days

When number of days decreases, number of men increases Hence it is inversely proportional.

Step 2 of 2:

Multiply directly and solve for $x$

$20\times60=x\times48\\1200=48x\\\\48x=1200\\x=\frac{1200}{48} \\x=25$

Hence 25 mens are required to costruct such a housing unit in 48 days.
