If (a+1) workers (In number) will do a work in (a+1) days then in how many days will (a+2) members of workers do the work ? 

Correct option is (D) \(\frac{(a+1)^2}{a+2}\) Work done by (a+1) works in (a+1) days = (a+1) (a+1) \(=(a+1)^2\) Number of days required to complete the same work by (a+2) members \(=\frac{\text{Total work}}{a+2}\) \(=\frac{(a+1)^2}{a+2}\)
