If every child has atleast 2 brothers,
minimum number of boys = 2+1 = 3
If every child has atleast 1 sister,
minimum number of girls = 1+1 = 2
minimum number of children = 2+3 = 5
minimum number of boys = 2+1 = 3
If every child has atleast 1 sister,
minimum number of girls = 1+1 = 2

If every child has atleast 1 girl
So 1+1=2
And if there are atleast 2 brothers
So 2+1=3
Hence the least number of children in the family is 3+2=5
