After working for 6 days, Ashok finds that
only 1/3 rd of the work has been done. He
employs Ravi who is 60% as efficient as
Ashok. How many days more would Ravi,
take to complete the work?
Answers
Answer:
20 days more will be required to complete the work
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
Answer:
20 days more will be required to complete the work
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) x (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
