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 ????*

ReplyDelete..... Essa Atelier’s client.
Let the numbers be A, B, C, D.
ReplyDeleteA= 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
Jiji
Exactly how i solved mine..d love for maths tho!
DeleteLol...its funny how she will forget 4 digits but remembers this complicated word algebraic puzzling Mathphysics

ReplyDeleteA=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
QED
Anything math, always gives me instant headache

ReplyDeleteFour 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
4829 I calculated within 50 mins
