Answer 2

Explanation:

Let Nishu take x days to complete the work alone.

∴ Total work done by Nishu in 1 day = 1x

Also, Pintu takes (x + 6) days to complete the work alone.

∴ Total work done by Pintu in 1 day = 1x+6

Total work done by both in 1 day = (1x + 1x+6)

But, both take 4 days to complete the work together.

∴ Total work done by both in 1 day = 14

∴ 4(2x + 6) = x(x + 6)

∴ 8x + 24 = x2 + 6x

∴ x2 + 6x – 8x – 24 = 0

∴ x2 – 2x – 24 = 0

∴ x2 – 6x + 4x – 24 = 0

∴ x(x – 6)+ 4(x – 6) = 0

∴ (x – 6) (x + 4) = 0
