We can see that the total number of people at the party must be divisible by 6 since the ratio is 5:1(add 5+1 to get 6).
From the second sentence,the total must be divisible by both 6 and 4,which means that the number would be divisible by 12.
The only number that is not divisible by 12 is 258.

So option b.

You forgot to count children in people. The total shouls be divisible by 8. Answer remains the same.

It's very simple, we are looking for a number that is both multiple of 6(F=5M so the number must be divisible by 5+1=6) and of 4 (A=3C so 3+1=4)

Only B is not multiple of 4

\frac{258}{4}=64.5

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.

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.
