Answer Posted / hradayeshkumar sharma
If x is the total amount of work to be done, then
a does x/10 of work in one day while,
b does x/15 of work in one day
If y is the number of days that a and b have to work
together to finsh x amount of work then the equation becomes
(x/10)*y + (x/15)*y = x
which results into y = 6.
