Answer 2

$\huge \mathfrak{ \color{blue}{ \underline{Solution}} \: }$

$\sf{35m \: trench \: can \: be \: dig \: by \: 15 \: men}$

$\sf{1m \: trench \: can \: be \: dig \: by = \frac{15}{35} }$

$\sf{84m\: trench \: can \: be \: dig \: by = \frac{15 \times 84}{35} = \frac{3 \times 84}{7} }$

84m trench can be dig by 3 × 12 = 36 mens
