x+1 men will do the work in x+1 days, find the number of days that x+2 men can do the same work in.
Given x+1 men will do the work in x+1 days
Therefore Wlwe know that,
x+1 men ⇒x+1 days
1 man ⇒(x+1)∗(x+1) days
x+2 men ⇒ (x+2)/(x+1)² days
∴,x+2 men can do the same work in
(x+2)/(x+1)² days
Hence x+2 men can do the same work in
(x+2)/(x+1)² days
