weeeeeb [17]

<h3>Answer:</h3>

Number of students who chose history as favorite subject = 25

Number of students who chose music as favorite subject = 60

<h3>Step-by-step explanation:</h3>

Let the total number of students be 's'.

Number of students who chose history as favorite subject = $\frac{1}{6}$ of (Total number of students) = $\frac{1}{6}\times \textrm{s}$ = $\frac{1}{6}\textrm{s}$

Number of students who chose history as favorite subject = $\mathbf{\frac{1}{6}s}$

Number of students who chose music as favorite subjects = $\frac{2}{5}$ of (Total number of students) = $\frac{2}{5}\times \textrm{s}$ = $\frac{2}{5}\textrm{s}$

Number of students who chose music as favorite subjects = $\mathbf{\frac{2}{5}s}$

Number of students who chose neither history nor music as favorite subject = 65

Total number of students = (Number of students who chose history as favorite subject) + (Number of students who chose music as favorite subject) + (Number of students who chose neither history nor music as favorite subject)

$\mathrm{s=\frac{1}{6}s+\frac{2}{5}s+65}$
