The ratio of a man's work and a woman's work is 5:3.If 3 men and 5 women take 17 days to do a piece of work,how many days will 5 men and 3 women take?

(A)20
(B)15
(C)19
(D)10
(E)8
It takes time and effort to explain, so if my comment helped you please press Thanks button :)



Just because something is hard doesn't mean you shouldn't try,it means you should just try harder.

3 men = 5 women

10 women takes 17 days to complete the work

5 men = 5*5/3 = 25/3 women

25/3 + 3 women will take = 170/(34/3) = 15 days
