Question

Madan and Jagdish working together can do a piece of work in 10 days. Madan alone can do it in
15 days. How long will Jagdish take to do the same work ?​

Answer 1

Answer:

Jagdish would take 6 days to finish the work.

Step-by-step explanation:

Let the time taken by Jagdish and Madan to do the work be "x" and "y" days respectively.

Therefore, work done by Jagdish and Madan in 1 day are "1/x" and "1/y" respectively.

y=15 [From Given]

1/x + 1/y = 1/10

1/x + 1/15 = 1/10

1/x = 1/10 +  1/15

     = (15+10)/150 = 25/150 = 1/6

1/x = 1/6

∴ x = 6

∴ Jagdish would take 6 days to finish the work
