Vault code Math genius riddle
Please find the Vault code consisting of 5 different numbers … (1-9) …
1. The sum of the first digit and the sum of the third digit is 10 ..
2. The first digit is a square of the fifth digit
3. The fourth digit is equal to the second digit plus 1
4. The sum of the digits is 22
What is the Vault code?
Answer– 94153
Explanation-
Let the number be VWXYZ
Conditions:
(1) V + X = 10
(2) V = Z^2 => V = 4 / 9 and Z = 2 / 3 (V = 1 => Z = 1 which is NOT allowed.)
(3) Y = W + 1
(4) V + W + X + Y + Z = 22
Applying (1) and (3) in (4) => 10 + 2W + 1 + Z = 22
=> 2W + Z = 11 (5)
Exploring possible values from (2):
(a) If V = 4, Z = 2 then (5) => 2W = 9 which is Impossible.
(b) If V = 9, Z = 3 then X = 1, W = 4, Y = 5.
Hence the code is 94153.
Answer:94153
We know that the answer will have the following pattern.
x y 10-x y+1 sq.root(x)
We know that x cannot be taken as 5 as 5^2=25>22.
If we take x as 4^2=16,
1st digit=16
5th digit=4
16+4=20
only 2 is left and thus it is not possible.
Only if x is taken as 3 will we get a correct answer .
ponder on this password too:
1 5 9 6 1
1st no.= 1*1=1
3rd no.=10-1=9
4th no. = 2nd no. +1 => 5+1=6
total of digits => 1+5 +9 +6 +1= 22 kaboom!!!
