The answer is 35 days....
A alone: 14 days, A+B : 10 days.. Always remember that TIME is inversely proportional to NUMBER OF PEOPLE. So B has to take more than '10' days for sure.
A in 1 day: 1/14 work.... A+B in 1 day: 1/10 work... So B in 1 day= 1/10 - 1/14 = 7-5/70 = 2/70 work = 1/35 work
B, 1 day = 1/35 work... so 1 work = 35 days
ok

Answer: B can do work in 35 days
Explanation:
A = 1/14
A + B = 1/10
1/14 + B = 1/10
= 1/10-1/14
= 2/70 or 1/35
B = 1/35
