(#M40007825) SELF QUESTION Keep an EYE

A alone can do a work in 12 days. A and B together finished work and got rs.54 and rs.18 respectively. In how many days was the work finished?
a) 12
b) 14
c) 9
d) 10
e) 8

Solution

A does the work in 12 days
and A and B together finished work and got rs.54 and rs.18 respectively
so B will do work in 12*3 = 36 days (because he got 1/3 money relative to other)
so one day work = 1/12 + 1/36 = 4/36 = 1/9
so total days required = 9
