a can do a piece of work in 10 days b can do the same work in 15 days.If they work together and finish it,then out of total wages 3000,a will get?
-------
a did 1/10 th of the job each day
b did 1/15 th of the job each day
-------
(1/10)x + (1/15)x = 3000
15x + 10x = 450000
25x = 45000
x = 1800 (amt. a should get)
3000-x = 1200 (amt. b should get)
