Question

if 24 workers can build a wall in 15 days,how many days will 8 workers take to build a similar wall??

Answer 1

Men required to finish a work in 15 days = 24
So, men required to finish a work in 1 day = 24×15....(1)
Let 8 men take x days so,
men required to finish a work in 1 day = 8 * x ...(2)
From 1 and (2)

8 * x =24×15
x= (24×15)/8
=45days
