Question

after working for 6 days bikash find thak 1/3 of work has been done. he employees prabir who is 60% as efficient as bikash. how many days more would prabir take to complete the work.
​

Answer 1

Answer:

Step-by-step explanation:

In 6 days, the work done by Ashok = 1/3

Therefore, Ashok can complete a work = 18 days

In one day, work done by Ashok = 1/18

Efficiency of Ravi = 60%

Therefore,in a day, work done by Ravi = (1/18) × (60/100) = 1/30

Let the remaining days be n

Remaining work = 1-1/3 = 2/3

Therefore,

or, (n/30) = 2/3

or, (n/10) = 2

or, n = 20 days

Therefore B will take 20 days to complete the remaining work
