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.

Solutions

Expert Solution

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
