6) (9*9) + 9 + 9 + (9/9) = 100
Code:
(9*9) = 81
81 + 9 = 90
90 + 9 = 90
99 + (9/9) = 99 + 1 = 100
7) It will take him 12 days
Code:
Day 1 : Start - 0 After Climb - 4 After Sleep - 1
Day 2 : Start - 0 After Climb - 5 After Sleep - 2
Day 3 : Start - 0 After Climb - 6 After Sleep - 3
Day 4 : Start - 0 After Climb - 7 After Sleep - 4
Day 5 : Start - 0 After Climb - 8 After Sleep - 5
Day 6 : Start - 0 After Climb - 9 After Sleep - 6
Day 7 : Start - 0 After Climb - 10 After Sleep - 7
Day 8 : Start - 0 After Climb - 11 After Sleep - 8
Day 9 : Start - 0 After Climb - 12 After Sleep - 9
Day 10 : Start - 0 After Climb - 13 After Sleep - 10
Day 11 : Start - 0 After Climb - 14 After Sleep - 11
Day 12 : Start - 0 After Climb - 15
(There must be some sort of equation, it's escaping me right now)
8) Well, if you take it as an independent case, it's like a coin. It's either a boy or a girl; 50/50. If you take genetics into acount, then if I remember right, there's a slightly better chance of it being a girl.
