RRB Paramedical Staff Nurse Model Paper 7

Work done by A in 1 day $=\frac{1}{16}$
Work cone by B in 1 day $=\frac{1}{24}$
Work done by A,B and C in 1 day $-\frac{1}{6}$
Then work done by C in 1 day
=(A+B+C)'s 1 day work - A's 1 day work - B'd 1 day work
$\frac{1}{\mathit{c}}=\frac{1}{6}-\frac{1}{16}-\frac{1}{24}$
$\frac{1}{\mathit{c}}=\frac{8-3-2}{48}$
$=\frac{3}{48}=\frac{1}{16}$
Thus ration of wages of A,B and C
$-\frac{1}{\mathit{A}}:\frac{1}{\mathit{B}}:\frac{1}{\mathit{C}}-:\frac{1}{15}:\frac{1}{24}:\frac{1}{16}$
$=3.2:3$  (taking LCM)
Share of A $=\frac{1}{3+2+3}\times 400$
$=\frac{1}{8}\times 400=\mathrm{Rs}150$
Share of B $=\frac{2}{3+2+3}\times 400$
$=\mathrm{Rs}100$
Share of A $=\frac{3}{3+2+3}\times 400$
$=\mathrm{Rs}150$
