Time and Work Practice Test 2 with solutions

Let work done by Shruti in one day = $\frac{1}{\mathit{x}}$
Work done by Rohan in one day = $\frac{1}{4}$
Work done by Sohan in one day = $\frac{1}{6}$
Work done by all of them in one day = $\frac{1}{2}$
According to the question,
$\frac{1}{\mathit{x}}$ = $\frac{1}{2}-\frac{1}{4}-\frac{1}{6}$
$\frac{1}{\mathit{x}}$ = $\frac{6-3-2}{12}$ = $\frac{1}{12}$
So, the required Ratio = $\frac{1}{4}:\frac{1}{6}:\frac{1}{12}$ = 3 : 2 : 1
Shruti’s share of money = $\frac{1}{6}\times 7200$ = Rs 1200
