Answer:
60 days
Explanation:
Given that:
Time taken by Chandu alone = 15 days
Time taken by Chandu and Balaji (working together = 10 days
Chandu's work rate = 1/ time taken = 1/15
Working together (work rate) = 1/10
Chandu's rate + Balaji's rate = working together rate
Let Balaji's rate = 2/x
1/15 + 2/x = 1/10
2/x = 1/10 - 1/15
L. C. M of 10 and 15 = 30
2/x = (3 - 2) / 30
2/x = 1/30
x = 60
Hence, it will take Balaji alone 60days to complete the same task.
