Half Rupee

Reema and Mona went to shopping, they had spent half of the money plus Rs.2 in butcher shop?
Then they had gone to xxx spent half of the remaining +Rs.5. Then they went to bakery and spent half of the remaining amount. Finally Rs. 5 was left with them. How many rupees did they carry?
Let the number of rupees they carried = x
x/2 + 2 was spent in the butcher’s shop.
The remaining money was x/2 – 2.
(x/2 – 2)/2 + 5 was spent at xxx.
The remaining money was (x/2 – 2)/2 – 5.
[(x/2 - 2)/2 - 5]/2 was spent at the bakery, and an equal amount remained. So,
[(x/2 - 2)/2 - 5]/2 = 5
(x/2 – 2)/2 – 5 = 10
(x/2 – 2)/2 = 15
x/2 – 2 = 30
x/2 = 32
x = 64
They carried 64 rupees.
