Answer:
1 day work of A=1/14
1 day work of (A+B)=1/10
Given:A+B=1/10
or,1/14+B=1/10
or,B=1/10-1/14
Or,B=2/70=1/35
Now, 1/35 part of work is done in 1 day by B.
So,1 work will be done in 1÷1/35=35 days.
B can alone do the work in 35 days.

A can complete the work in 14 days
So, A's 1 day's work = 1/14
A and B can complete the same work in 10 days
So, A and B 1 day's work = 1/10
Let the days taken to complete the same work By B be x
B's 1day work = 1/x
Equation formed :
So, B alone can do the same work in 35 days.
