Guyz let hack this
Here is the tea

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 ?

    1. 4 (8/2 = 4)

    2. 8 (8+2 = 10)

    3. 2 (2+8 = 10)

    4. 9 (8+1 = 9)

    4+8+2+9 = 13

    Her pin is 4829.

    ABCD

    Since A is half of B, B must be even. So it must be one of:

    1 2 ? ?
    2 4 ? ?
    3 6 ? ?
    4 8 ? ?
    0 0 ? ?

    Since B and C add up to 10, B cannot possibly be 0. So that only leaves

    1 2 8 ?
    2 4 6 ?
    3 6 4 ?
    4 8 2 ?

    If we fill out (D = B + 1) we get 4 possible combinations:

    1 2 8 3
    2 4 6 5
    3 6 4 7
    4 8 2 9

    Add each set to get:

    1 + 2 + 8 + 3 = 14
    2 + 4 + 6 + 5 = 17
    3 + 6 + 4 + 7 = 20
    4 + 8 + 2 + 9 = 23
