Question

A, B, and C can do a piece of work in 8 days. B and C together do it in 24 days. B alone can do it in 40 days. In what time will it be done by C working alone?​

Answer 1

Answer:

60 days

Step-by-step explanation:

Consider C can do total work alone in x days

So, 1/x + 1/40 = 1/24

1/x = 1/24 - 1/40

1/x = 1/60

Therefore , x=60 days

Answer 2

Answer:

c takes 60 days.

Step-by-step explanation:

a+b+c= 1/8........(i)

b+c=1/24............(ii)

b=1/40

b take40 days..............(iii)

solving equation (ii)and (iii)

we get,

= 1/40-1/24

=16/(40*24)

c =1/60........(iv)

c takes 60 days.
