Question
Arun and Varun take up an assignment together. Arun
finishes 3 units per day, while Varun can complete the entire assignment in 12 days. The total work amounts to 60 units. Determine how many days it takes for both to finish it together.Solution
ATQ,
Let, the time taken by Arun and Varun to do the work be ‘x’ days.
Units of work done by Varun in a day = 60 / 12 = 5 units
So, 60 / x = 3 + 5 = 8
60 = 8x
x = 60 / 8 or (45/2)
