Lockdown Brain Teaser......

We may be locked down but our brains are still functioning.....right?






A house wife forgot her ATM pin. Which is four digit number, but luckily she remembered some hints on how to recall the pin. Here are some of the clues:


The first digit is half of the 2nd

The sum of 2nd and 3rd is 10

The 4th is equal to the 2nd plus 1

The sum of all the digit is 23.

*What is the atm pin ????*

  2. The pin is ( 4 8 2 9 )

    half of 8 is 4
    8+2 = 10
    8+1 = 9

    4+8+2+9 = 23

    😁😁😁😁😁

  6. Let the numbers be A, B, C, D.
    A= B/2
    B+c =10
    D=B+1
    A+B+C+D=23
    Solving a for B
    (B/2 + 2B + 20-220-2B+2B+2)/2 = 23
    3B + 22 = 46
    3B = 46-22
    3B = 24
    B =24/3
    B = 8
    Therefore
    A= 4
    B =8
    C= 2
    D= 9
    The numbers are 4,8,2,9

    A=2B ,A=B/2 ...EQUATION 1
    B+C=10
    C=10-C.....2
    D=B+1 ....3
    A+B+C+D=23....4
    SUBSTUTUTE FOR C AND D AND A IN EQUATION 4 WE GET
    B/2 +B+(10-B)+(B+1)=23
    THEREFORE 3B=24
    B=8
    FROM EQUATION 1
    A=8/2=4
    FROM EQUATION 3
    B+C=10
    C=10-8
    C=2
    FROM EQUATION 3
    D=B+1
    D= 8+1
    9

    PIN IS 4829

    Four digits abcd
    a/2 =b ....eq 1
    b+c =10...eq2
    d =b+1...eq3
    a+b+c+d= 23...eq4

    a =2b from 1
    c= 10-b from2
    Solve for b
    2b+b+(10-b)+b+1=23
    3b+b-b=23-10-1
    3b=12
    b=4
    From 1..a=2b=2×4=8
    From 2..b+c=10, c=10-4=6
    From 3..d=b+1=4+1=5
    From 4..a+b+c+d=23
    8+4+6+5= 23
