No. Very often the mean will not be part of the data set. In most countries, the average number of children per family is some fractional number. For example, in 2006, the mean number of children in a UK family was 1.8. However, I have yet to come across 0.8 of a child!

Each child in a family has at least 5 brothers and 3 sisters What is the smallest number of children the family might have?
8 The answer is 9. If you are a boy, it would be 6 boys and 3 girls, but it you were a girl it would be 5 boys and 4 girls because you cannot be your own brother or sister. 10, the combination of 6 brothers and 4 sisters. Then each is guaranteed to have 5 brothers, 3 sisters. In the examples for 9 total, the girls in 6-3 would only have 2 sisters, and vice versa for the boys in 5-4. It seems 9 is the correct answer for the way the question is worded. If the question were worded "What is the least number of of children that would guarantee that each child has five brothers and three sisters ?" then 10 would be correct.

If Sophie has 5 more brothers than sisters and her brother Joe has half as many sisters than brothers how many children in the family?
Suppose there are B boys and G girls. Then Sophie has B brothers and (G-1) sisters - remember to leave Sophie out. So B = (G-1) + 5 ie B = G + 4 Also Joe has (B-1) brothers and G sisters So (B-1) = 2*G Substituting the value of B from Sophie's equation into this one gives (S+4 - 1) = 2*G ie G+3 = 2*G Subtract G from both sides: 3 = G and then B = G+4 = 7 So number of children in the family = B+G = 7+3 = 10.
