# A does a work in 10 days and B does the same work in 5 days.

A does a work in 10 days and B does the same work in 5 days. In how many days they together will do the same work ?

## Answer/Solution

3/10

### Steps/Work

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+1/5)=(1+2/10)= 3/10

C

So,

A's 1 day work = 1/10

B's 1 day work = 1/15

(A+B)'s 1 day work =

(1/10+1/5)=(1+2/10)= 3/10

C
