Can you guess the number?

Question

Hi, 

Feeling bored???

Are you ready to play an interesting trick??

Let's start.

Think of a number. Follow the below steps.

1. Add 2 with the number

2. Multiply result with 5.

3. Add 3 with the answer.

4. Multiply 2 to the resultant number and add it with four.

5. Divide the answer with 10. 

Now if you say the resultant value.....I can guess the number thought by you!!!!!

Post your resultant value.....

Answer 1

6+2=8*5=40+3=43*2=86+4=90/10=9

Can you guess my number?

I will give you a hint, the number has 4 digits

Answer 2

I think the secret is you just subtract 3 from the answer to get the initial number...

Here is my reasoning

Let x = number

step 1:

x + 2

step 2:

5(x+2)

step 3:

5(x+2) + 3

step 4

2 * (5(x+2) + 3) + 4

step 5

(2 * (5(x+2) + 3) + 4 )/ 10 

So

if R is final total

(2 * (5(x+2) + 3) + 4 )/ 10  = R

2 (5x + 10 + 3) + 4) = 10 R

10 x + 20 + 6 + 4 = 10 R

10x + 30 = 10 R

10x = 10R - 30

divide both sides by 10

x = R - 3

 

 

 

Answer 3

I got the answer 90. 4+2=8 multiply by 5=40+3=43 multiply by 2=86+4=90

Comments

4+2 = 8 ?

I think you mean

4+2 = 6

multiply by 5 = 30 + 3 = 33, multiply by 2 = 66. add 4 = 70. Divide by 10 = 7

---

The number you thought is 87.

Answer 4

My answer is 16. Can you guess my number?
