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
