Відповідь:

16 або 8 - дві відповіді

Покрокове пояснення:

НСД (12; 20) = 4
у числа 4 э дільники 1, 2, 4
"розділити" всю кількість (12+20=32) на одну групу - то не варіант для змагань
отже ділити могли або на 2 або на 4 групи
32/2 = 16 (по 16 участників в 2 групах (12/2=6 хлопців та 20/2=10 дівчат))
32/4 = 8 (по 8 участників в 4 групах (12/4=3 хлопця та 20/4=5 дівчат))
