Smitha had a number of cookies. After eating one, she gave half the remainder to her sister. After eating another cookie, she gave half of what was left to her brother. Smitha now had only five cookies left. How many cookies did she start with?

The Answer is 23
Lets count backwards..
Smita had cookies  5
Before that, Smita Gave her brother half of what she had  5*2 = 10
Before that, She ate one  10+1 = 11
Before that, She gave her Sister half of what she had  11*2 = 22
Before that, She ate one  22+1 = 23
Lets hope Smita cuts down on weight as well!!! :P
Cheers!!!
