Question

Vitin can do a piece of work in 24 days while Raman can do it in 30 days. In how
many days can they complete it, if they work together?​

Answer 1

Answer:

Vitin can in 24 days finish the full work i.e 100% or 1 of it.

∴ Vitin can in 1 day finish 1/24th of the work.

Raman can in 30 days finish the full work i.e 100% or 1 of it.

∴ Raman can in 1 day finish 1/30th of the work.

Therefore amount of work both of them can do in 1 day

= 1/24+1/30

= 24+30/720

= 54/720

= 3/40

Therefore time taken by them = 1/(3/40) = 40/3 = 13

1/3 days
