1dollar for the beggar=x/2-1=x-2/2
remaining=x-2/2
spends 1/2in hotel x-2/2×1/2= x-2/4
2dollars for waiter ,x-2/4-2=x-10/4
1/2 dollar for shopping ,x-10/4-3= x-32/8
So total money ,x=
x-32/8=0
x-32=8
x=32+8
=42//

Answer

Given information:
- A woman goes shopping with a certain amount of money.
- She spends half of the money on shopping.
- She gives $1 to a beggar.
- She goes to a hotel and spends half of the remaining money.
- She gives $2 to a waiter.
- She buys some goods with half of the remaining money.
- She gives $3 to a receptionist.
- We need to find out how much money she had in the beginning.

Step-by-step solution:

Let's assume the amount of money the woman had in the beginning is 'x' dollars.

1. Spending on shopping:
- She spends half of the money, which is x/2 dollars.
- The remaining amount is x/2 dollars.

2. Giving money to a beggar:
- She gives $1 to the beggar.
- The remaining amount is (x/2) - 1 dollars.

3. Spending at the hotel:
- She spends half of the remaining amount, which is [(x/2) - 1]/2 dollars.
- The remaining amount is [(x/2) - 1]/2 dollars.

4. Giving money to a waiter:
- She gives $2 to the waiter.
- The remaining amount is [(x/2) - 1]/2 - 2 dollars.

5. Buying goods:
- She buys goods with half of the remaining amount, which is {[(x/2) - 1]/2 - 2}/2 dollars.
- The remaining amount is {[(x/2) - 1]/2 - 2}/2 dollars.

6. Giving money to a receptionist:
- She gives $3 to the receptionist.
- The remaining amount is {[(x/2) - 1]/2 - 2}/2 - 3 dollars.

According to the given information, the remaining amount of money at this stage is zero. So we can set up the equation:

{[(x/2) - 1]/2 - 2}/2 - 3 = 0

Simplifying the equation:

[(x/2) - 1]/2 - 2 = 6

[(x/2) - 1]/2 = 6 + 2

(x/2) - 1 = 8 * 2

(x/2) - 1 = 16

x/2 = 16 + 1

x/2 = 17

x = 17 * 2

x = 34

Therefore, the woman had 34 dollars in the beginning.
