The Kind Grandparents (Posted on 2003-09-30) Difficulty: 3 of 5
When you were born, both of your rich grandparents made a deal with your parents, to do with what money they'll give you for birthdays. Grandad's deal was :

I'll give you 1 for your first birthday. Then, the amounts that I give you each year will double every time

and Grandma said :

I will start by giving you 1 for your first birthday. Then, the amount I give you will be the combined total of all the last birthday presents that I have ever given you up to that point. Plus, every birthday you have that's a multiple of five, I'll give you an extra five pounds.

a)What amount of money do they each pay you for your 15th birthday


Who would have given you the most after 27 years?

i think i have the right answer | Comment 15 of 17 |
if i understand the questions correctly, the grandfather gave16,384on the 15th birthday and the grand mother gave 10,837. Now as far as the second part the answer is the grandfather w/ 268,435,395. after all the question was who gave the most after the 27 yrs. if you add all that the grandfather gave over the entire 27 yrs. you get 268,435,395. where as the grandmother only gave 88,756,884.
