Question

How it will be solved?


question:- Think a number. Double the number and add 9 to it then add the number you started with. then divide the amount by 3 and also subtract 3 from the quotient. What The Number do you get?



​

Answer 1

we get the no. of which we first thought

for eg .2

double of 2 is 4

4+9=13

13+2=15

15÷3=5

5-3=2

so we get 2only

Answer 2

Let the number be "x".

Now, doubling the number → 2x

Adding 9 → (2x + 9)

Adding the number, Started with(i.e., "x")
→ (2x + 9) + x = (3x + 9)

Now dividing the amount by 3, we get:
→ (3x + 9)/3 = (x + 3)

Now, subtracting 3, we finally get:
→ (x + 3) - 3 = x.

The number is again the same, with which we started, (i.e., "x").

You can even consider a particular value of x, (like x=4, or 7, or any value...).

Thankyou!!!
