Five times as many females as males --> F = 5M.

Three times as many adults as children --> (F + M) = 3C.

The number of people at the party = F + M + C = 3C + C = 4C.

The number of people at the party must be a multiple of 4. The only answer choice which is NOT a multiple of 4 is B.

Answer: B.

Here adults is assumed to be M+F. However, even children can also be categorized into Male/Female?

Adults is a categorization based on AGE so children could be classified as a male or female.

So i find it a bit awkward to classify total no. of people (T) = M + F + Children?

T= M+F (gender basis) and T = A+C (Age basis)

kindly correct me if i am wrong.

Thank you.
