**Ashish wants to complete his apartment renovation in 25 days**

Let ashish remove x number of men.

So he needs 24-x men to complete the remaining work

Let

Men= M, Days=D, Time/hours = T, Work = W

M1D1T1W2 = M2D2T2W1

Note that W2 is on left side and W1 is on right side

M1 = 24, D1 = 6, W1 = 80% of 1 = 0.8

M2 = 24-x, D2 = 4, W2 = 20% of 1 = 0.2

(24 x 6 x 0.2) = (24-X x 4 x 0.8 )

9 = x
