There were A adults, Sm male students, and Sf female students.
<span> </span>
<span>Sm = 1 + 7A </span>
<span>Sf = Sm/2 </span>
<span>A + Sm + Sf = 82 </span>
<span>A + (1 + 7A) + (1 + 7A)/2 = 82 </span>
<span>2A + 2 + 14A + 1 + 7A = 164 </span>
<span>23A + 3 = 164 </span>
<span>23A = 141 </span>
<span>A = 7 </span>
<span>The number of male students is 50. </span>
<span>The number of female students is 25.</span>
