### Find 4 digit number brain teaser **Answer:**

4321

**Explanation:**

Since we are given 6 numbers however only 4 digits need to be found which means, 2 numbers will have duplicate digits with correct position. Here are highlighted digits which match this.

6358 | 6728 |

9306 | 1191 |

4882 | 5627 |

So now we have 2 digits with their positions so lets assume number to be: **x32y**

We are left with 2 numbers in which we need to find 2 digits, one from each.

1191 –> from this , we know that number cannot be 9, since 9**3**06 had number 9 and as per statement only one digit should be correct and we already know that it was 3.

Which leaves us with digit to be as 1 however as of now we don’t know if it would be first or at 4th position.

4882 –> 6**3**58 and 67**2**8 tells that digit cannot be 8.

It cannot be 2 as it is already there in other combo which leaves digit 4 at first position.

It also tells that digit 1 from above number(1191) should be at fourth position.

So now we have number as 4321
