Question

36. Ankith takes as long Balaji

Answer 1

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.
