50% of all children have brown hair ???

Statement I

70% of boys have brown hair. We dont know the number of boys or the total number of children, or the number of girls.

Insufficient.

Statement II

30% of all the children are girls with brown hair, we dont know anything about boys,

Insufficient.

Combining I & II

70% of boys have brown hair
30% of all the children are girls with brown hair

we dont know the number of girls with no brown hair and no. of boys.

Insufficient.

Hence E is the answer.

Whats the OA?
