Answer:
Recycling club cooking club Total
total
Male 55 65 120
Female 67 63 130
Total 122 128 250
male total= 250-130 = 120
128 engaged in cooking club
∴250-128= 122 ( those who surveyed for recycling )
male ( recycling club ) = 122-67 = 55
from there we can find the male number for the cooking club
⇒ 120-55=65
lastly the female for the cooking club
130-67=63 or 128-65=63
