Answer 1

Given : Anil can do a work in 15 days while sunil can do it in 25 days.

To Find : How long will they take if both work together?

Solution :

Let both can do this work together in 1/a days!

Now, if they can do it work together,

Then, 1/a = 1/15 + 1/25

✏ 1/a = 1/15 + 1/25

✏ 1/a = 5 + 3/75

✏ 1/a = 8/75

✏8a = 75

✏ a = 75/8 days or 9⅜ days

Hence, 9⅜ days will they take if both work together.
