Solution

The correct option is D
3

Step 1
let the number be x
Step 2
Double the number, which is 2x
Step3
Add 9 with the result, which is 2x + 9
Step 4
Subtracting the number 3 from the result, 2x + 9 - 3
Step 5
Divide the result by 2, which is x + 3
Step 6
Subtract the number with which she has started initially from the number obtained in step5, which is x+3 -x = 3
So, the result is always 3.
