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!!!
