Question

15 men can construct a road in 12 days. How many men are required to construct the same road in 9 days?

Answer 1

Answer:

20 men

Step-by-step explanation:

15men=12days

xmen=9days

it is in inverse proportion as we increase the men's it will take less time to construct the road

so

15:9::x:12

=15×12=9x

9x=180

$x = \frac{180}{9} = 20$
