A lady was out for shopping. She spent half of her money in buying A and gave 1 dollar to a beggar. Further she spent half of her remaining money and gave 2 dollar to charity. Further she spent half of remaining money and gave 3 dollar to some children

• Let ‘x’ be the amount the lady had initially.
  
  1st transaction -> x/2 +1 , the remaining amount x - (x/2 + 1) = x/2 - 1 let it be ‘A’.
  
  2nd transaction -> A/2 – 2 be the remaing amount , let the reminder be ‘B’
  
  3rd transaction -> B/2 – 3 = 1
  
  Now solving the 3rd transaction we get the value of ‘B’ as 8
  
  Solving the 2nd transaction we get the value of ‘A’ as 20
  
  Solving the 1st transaction we get the value of ‘x’ as 42.

• lastly she has 3 rs
  so after charity she has 3*2=6 rs
  before giving 2 dollar she has rs 8 in hand
  and after giving 1 doller to beggear she has 8*2=16 rs
  it means before that she has 16+1 =17 rs
  so it is clear that in starting she has 17*2= 34 rs in hand
  
  start solving question from last
  thank u

• initially let x be the amount she has
  after buying A and gave 1 dollar to beggar she left with (x/2)-1=(x-2)/2
  then after buying B and gave 2 dollar to beggar she left with (x-2)/4- 2=(x-10)/4.
  and finally after buying c and gave 3 dollar to beggar she left with (x-10)/8 - 3= (x-34)/8
  (x-34)/8=remaining amount ,compare and get answer

• Bottom up strategy
  she has 1 dollar, she gave 3$ to children, all of these was half of what she spent
  so, 4X2 = 8
  
  similarly, she gave 2$ to charity and she was having 8$ already
  so 8+2 = 10, which was half of what she spent
  so 10X2 = 20
  
  at the beginning, she gave 1$ to beggar and half of what she spent on shopping,
  20+1 = 21
  21X2 = 42 Ans.

• total amount =34 dollar
  suppose total amount is X
  (X/2)+1+((X-20/4)+2+((X-10)/8)+3=X
  solve this equestion,we get X=34

• @SRINATH
  i had a look on the question and found that , question is incomplete . if u search at other places , it is given that at last she is left with 1 dollar . so after last transaction she still have 1 dollar.

• correct answer is 42 not 34, you can check it by taking total amount as 42.

• Ankesh patel, Please explain how could you write B/2 - 3 = 1. Rest of then things are fine
