Solution

The correct option is C $C$
$A$ can do $\frac{1}{5} t h$ part of the work in $12$ days.
$\Rightarrow$ $A$ can do the whole work in $(12 \times 5)$ days $= 60$ days.
$B$ can do $60 %$ of the work in $30$ days.
$\Rightarrow$ B can do the whole work in $(\frac{30 \times 100}{60})$ days $= 50$ days.
$C$ can do $\frac{1}{3} r d$ of the work in $15$ days $= 45$ days.
$∴$ $C$ will complete the work first.
