Ajeet works 4 times as fast as Sohan. If Sohan can complete a work in 20 days independently
Concept used:
Efficiency = (Total work / Total time taken)
Efficiency = work done in a single day
Calculation:
Efficiency ratio of Ajeet : Sohan = 4 : 1
So time ratio will be 1 : 4
So Ajeet takes it 20/4 = 5days
Together does in 1 day,
⇒1/5 + 1/20 = 1/4 part
Then Ajeet and Sohan can together finish the work in 4 days
