A housewife forgot her Bank account PIN Code which is a 5 digit number, but luckily she remembered some hints on how to recall this PIN Code.
ASSUME SHE SUBMIT BELLOW CLUE ON YOUR TABLE CAN YOU HELP HERE OUT???
Here are some of the clues:
1) The first digit is the 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 5th makes 14.
5) The sum of all the digits is 30.
What's the PIN Code?

Pls how did you get the answer? @iamOluwaBunmi
ReplyDeleteForm several Linear equations based on given assumptions, combine all and reduce into a single quadratic eqaution (b^2 + 2b -15 = 0) where b is the second number of the PIN). This equation gives b=3,& b=-5(which is ignored bease a PIN can't be a negative number). Then back substitute into your linear Equations. You will for sure come to an answer 93747 as the PIN.
ReplyDeleteHOPE this helps a lot.

possibilities for
ReplyDeletea 1,4,9
b 1,2,3
c 9,8,7
d 2,3,4
e 5,6,7
a+b+c+d+e = 30 is poosible only when a=9, b=3, c=7,d=4, e=7
Ans for:-
ReplyDeletea 1,4,9
b 1,2,3
c 9,8,7
d 2,3,4
e 5,6,7
a+b+c+d+e = 30 is poosible only when a=9, b=3, c=7,d=4, e=7
This is correct answer
