A takes 6 days less than time taken by B to finish the piece of work. if both A and B together can finish the work in 4 days find the time taken by B to finish the work

Let B alone finish the work in *x* days.

Therefore, A alone can finish the work in (*x* – 6) days.

Given, (A + B) can finish the work in 4 days

*x* ≠ 2, ∵ if *x* = 2, then A alone can finish the work in = (2 – 6) = –4 days, which is not possible.

∴** ****x**** ****= 12, i.e. B alone can finish the work in 12 days and A alone will finish the work in 12 - 6 = 6 days.**
