Question

Here is a brain teaser: Quantitative Reasoning.

A house wife forgot her bank account *PIN CODE* which is five digits number, but luckily she remembered some hints on how to recall this *PIN*.
Here are some of the clues
1) The *1st* digit is a square 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 *3rd* and the *5th* makes *14*
5) The sum of all the digits is *30*

What is the *PIN CODE*?

Answer 1

The code should be 93747...
the first digit is square of 2nd i.e square of 3 so 2nd digit is 3
The sum of 2nd and 3rd is 10 so 3 + 7 = 10 so 3rd number is 7 
4th number is 2nd plus one so 2 + 1 = 4
the sum of 3rd and 5th makes product 14 so 7 + 7 = 14
to check the answer sum of all the number makes up to 30 so
9 + 3 + 7 + 4 + 7 = 30
so the answer is correct

Answer 2

The answer is 93747.

1) The first digit is the square of the second digit. In this case, the first digit 9 is the square of the second digit 3.

2) The sum of the second and third digits is 10. Here, the second digit is 3 and the third digit is 7. 3 + 7 = 10.

3) The fourth digit equals the second digit + 1. In other words, the fourth digit is 3 + 1 = 4.

4) The sum of the third and fifth digits is equal to 14. Symbolically, 7 + 7 = 14.

5) Sum of all the digits is 30. 9 + 3 +7 + 4 + 7 = 30.
