Good morning.

Answer 2

Answer:

Work for 1 st 2 days = (1/8) + (1/12) = 5/24

∴ Work for 8 days = (5/24) x (8/2) = 5/6

∴ Remaining work = 1- (5/6) = (6 - 5) / 6 = 1/6

On 9th day, A's work = 1/8

Remaining work after 9 days = (1/6) - (1/8) = (4 - 3) / 24 = 1/24

B will finish this work in (12 x 1)/24 = 1/2 day

Clearly, A worked for 5 days from starting.

∴ Work done by A in 5 days = (1/8) x 5 = 5/8

∴ A's share = (5/8) x 1280 = 5 x 160 = ₹ 800
