Here is a brain teaser that is trending in all social media platforms & especially in WhatsApp. People are spending hours to find the correct solution for sharing in the groups.

Here we are providing the solution for this **math puzzle** with detailed steps on how to get the solution.

**QUSETION**

A house wife forgot her bank ‘ATM PIN’ which is a four digit number, but luckily she remembered some hints on how to recall this ‘PIN’

**Here are some of the clues**

1) The 1st digit is half of the 2nd

2) The sum of the 2nd and 3rd is 10

3) The 4th is equal to the 2nd plus 1

4) The sum of all the digits is 23

What is the ATM PIN ?

**ANSWER**

**4829 is the ATM Pin**

**Explanation**

Let The ATM Pin = 1000a + 100b + 10c + d

Equation 1: **2a = b** *(from 1st clue)*

Equation 2: **b + c = 10 ** *(from 2nd clue) *

Equation 3: **d = b + 1 ** *(from 3rd clue) *

Equation 4: **a + b + c + d = 23** *(from 4th clue)*

By Solving this we get,

From Equation 2 & 4 we get,

a + 10 + d = 23

=> a + d = 13

So let Equation 5: **a + d = 13**

From Equation 1 & 2 we get,

d = 2a + 1

So let Equation 6: **d = 2a + 1 **

Solving Equation 5 & 6 we get,

a + 2a + 1 = 13

3a = 12

Therefore, **a = 4**

From Equation 1 we get, b = 8

From Equation 2 we get, c = 2

From Equation 3 we get, d = 9

So the code is : (1000×4) + (100×8) + (10×2) + 9

=> 4000 + 800 + 20 + 9

=> **4829**
