Question

A can do a piece of work in 10 days while B alone can do it in 15 days. in how many days can both finish the same work?​

Answer 1

Firstly we will find 1 day work of both A and B then by adding we can get collective days for them,

So,

A's 1 day work =1/10

B's 1 day work=1/15

(A+B)'s 1 day work=(1/10+1/15)

=(3+2/30)

=1/6

So together they can complete work in 6 days

Answer 2

Answer:

In 6 days.

Step-by-step explanation:

Firstly we will find 1 day work of both A and B, then by adding we can get collective days for them,

So,

A's 1 day work = 1/10

B's 1 day work = 1/15

(A+B)'s 1 day work =

1/10 + 1/15 = 2+3/30

5/30 = 1/6

So, they together can complete work in 6 days.
