It's question 5

if he has grandchildren, and there's atleast ONE BIRTHDAY in each month


minimum = 12

but he has 5 pairs of twins

3 of them having birthdays in april

but one is counted so 5

112+5 = 17

he then has four kids / 2 twins, ASSUMING each is counted already, this is two more

= 19

but i'm wrong?

6 kids in April, 2 other sets of twins (let's assume they're in 2 different months), 9 months left over
6 + 4 + 9 = at least 19, so far

Twice as many females as males, so the number must be divisible by 3 (2/3 female, 1/3 male). The smallest number greater than 19 that's divisible by 3 is 21. E
