PLS CORRECT QUESTION ALSO

Question:

C)

5 57     days

D)

7 57    days

Solution:

Ans: (c)

60/100 work in 15 days

Let work is 100

60 work in 15 days

Therefore 100 work in 25 days

Capacity of ram = 60/15 = 4

capacity of rahim = 2

Capacity of rachel = 1

Required work = 40

Days = 40/(1+4+2) = 40/7 = 5(5/7)
