Answer :-

• M2 = no. of persons = 15 persons

using formula :-

$\\ \tt \frac {M_{1} × D_{1}} {W_{1} } = \frac { M_{2} × D_{2}} {W_{2}}$

Explanation :-

$\\ \tt \frac {M_{1} × D_{1}} {W_{1} } = \frac { M_{2} × D_{2}} {W_{2}} \\ \\ \tt \frac{5 \times 3}{1} = \frac{M_{2} \times 5}{5} \: \: \: \: \: \: \: \\ \\ \tt 5 \times 3 = M_{2} \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \\ \\ \tt \red{ M_{2} = 15 \: \: persons }$
