Question:

Ram completes 60% of a task in 15 days and then takes help of Rahim and Rachel. Rahim is 50% as efficient as Ram is and Rachel is 50% as efficient as Rahim is. In how many days will they complete the remaining work?

B)

8 13    days

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)
