Answer 2

$\huge \fbox \green{Answer:}$

$\sf \colorbox{pink} {A Can do a Piece of work in 8 day}$

$A's \: 1 \: day's \: work \: = \frac{1}{8} th \: of \: work$

$\sf \colorbox{pink} {Be can do a Piece work in 12 days.}$

$B's \: 1 \: day's \: work \: = \frac{1}{12} th \: of \: work$

$\sf \colorbox{pink} {C can do a Piece of work in 15 days}$

$So, \: C's \: 1 \: day's \: work \: = \frac{1}{15} th \: of \: work$

$∴(A + B + C)'s \: 1 \: day's \: work =$

$= \frac{1}{8} + \frac{1}{12} + \frac{1}{15}$

$= \frac{15 + 10 + 8}{120} = \frac{33}{120}$

A, B,C Together can finish the work in

$\frac{120}{33} = \frac{40}{11}$

$= 3 \frac{7}{11} \: days$
