Hey friend.....☺
HERE IS YOUR ANSWER
A can do work in 15 days
B can do it in 10 days
B works 5 days and leaves it
In this way B has done 1/2 of the work
(10 days= full work and 5days = half of the work)
Now A has to do only half of the work
(Again A does full work in 15 days that is taking 1 as complete work)
Now , multiply 15 × 1/2
=15/2
= 7.5 days is the answer
Hope it helps you
Thanks :-)
