Question

A can finish a work in 18 days b can do the same work in half the time taken by age and working together what part of the same work and they finish in a day

Answer 1

a finish work in 18 days
b finish work in in 9 days
So In one day a can do 1/18 part of work
And b can be 1/9 part of work
so total part of work done by both together
$\frac{1}{18} + \frac{1}{9} \\ \frac{1 + 2}{18} = \frac{3}{18 } \\ \frac{1}{6} \: part \: of \: work$
