9. A family I know has several children. Each boy in this family has as many sisters as brothers but each girl has twice as many brothers as sisters. How many brothers and sisters are there?

Answer: Option D

Explanation :

Lets assume no. of girls = x and boys = y
y = (x+1) ----------- (i)
As each boy have equal no. of sisters and brothers and he is not included in brothers.
so, 1 is for him in (x+1).

y = 2(x-1) ------ (ii)
as each girl have (x-1) sisters.
By solving eq. (i) and(ii)
girls = 3 and boys = 4
