Answer:
Step-by-step explanation:
Given,
'A' can do a piece of work in 10days
'B' can do the same piece of work in 15days
To Find :
In how many days work will complete if both 'A' and 'B' work together?
Solution:
given,
'A' can do a piece of work in 10days
'B' can do the same piece of work in 15days
Adding both one day work done by them together:
L.C.M of 10,15 = 30
hence, if we reciprocaled this this we will get work done by A and B together
= 6
Since, A and B together can complete the work in 6days
