Answer 2

Given:

Time taken by A and B to complete the job together = 10 hours

Time taken by A alone = 25 hours

To Find:

Time can B take to complete the same job working  alone

Solution:

Let the time taken by B = x hours

Thus, substituting values in equation -

= 1/x + 1/25 = 1/10

1/x = 1/10 - 1/25

1/x = 15/250

1/x = 3/50

Answer: B will take 50 hours to complete the work.
