A can do work=15 days
means A can do work in 1 day=1/15
B can do work in 1 day=1/30
so A+B can do work in 1 day=1/15+1/30=3/30=1/10
It means they will complete the work in 10 days.
means A can do work in 1 day=1/15
B can do work in 1 day=1/30
so A+B can do work in 1 day=1/15+1/30=3/30=1/10
It means they will complete the work in 10 days.

A can do in 15 days and b also do the same work in 30 days .mean15×a=b×30 and we come to know 2b=a so if both do work together that b do in 30 days so b+2b×x=30×b.3b×x=30b.x=10
