Question:
This riddle must be done IN YOUR HEAD and NOT using paper and pen or a calculator. Try it!
Take 1000 and add 40 to it. Now add another 1000 to it.
Now add 30. And another 1000.
Now add 20. Now add another 1000. Now add 10.

Re: Brain Teasers
You are on your way to visit your Grandma, who lives at the end of the valley. It's her birthday, and you want to give her the cakes you've made.
Between your house and her house, you have to cross 7 bridges, and as it goes in the land of make believe, there is a troll under every bridge! Each troll, quite rightly, insists that you pay a troll toll. Before you can cross their bridge, you have to give them half of the cakes you are carrying, but as they are kind trolls, they each give you back a single cake.
How many cakes do you have to leave home with to make sure that you arrive at Grandma's with exactly 2 cakes?

So I presume you began with 2 cakes and ended up at Granny's with 2 cakes?
