I am not sure this question belongs here, but anyway, if the correct answer is seven, how many boys should there be and how many girls? Pretend that you are one of these boys, do you have two brothers and four sisters? Now pretend you are one of the girls. Do you have two brothers and four sisters? Be sure not to count yourself.
 
yeah, thatz wat is bugging me.

question states a child and does not mentions the sex.
 
So if there are seven children does it work with 6 girls + 1 boy? No. Does it work with 5 girls + 2 boys or how about 4 girls + 3 boys? Try it like I said with all the possible splits of seven and see if any of them works.
 
the only possible combinations are:

4G+2B+1G = 7 CHILDREN
(internally, each boy won't have 2brothers and sister will increase to 5)
4G+2B+1B = 7 CHILDREN.

If we consider 1/4G+1/2B ??
But this time atleast 4 sis and 2 bro rqmnt will b completed.
each child will have atleast 4 sis and 2 bro.
so, least children will b 1G+4G+2B+1B= 8 children!

i think thatz it.

1G+4G+2B+1B is not 10 children. Perhaps you need to use a calculator.
 
is it correct now??
 
Yup, looks correct; 5 girls and 3 boys must be the minimum criteria fufilled.
