A problem by Pratyush Pushkar
You are given a thousand Re. 1 coins and 10 pouches. Now, you have to divide these coins in the given pouches in a manner that if someone asks you for any amount between Re.1 to Rs.1000, you should be able to give the amount by just giving the pouches. You are not allowed to open pouches for that.
How many pouches you would prepare
The answer is 10.
