A man desired to get into his work building, however he had forgotten his code.

However, he did recollect five pieces of information

-> Sum of 5th number and 3rd number is 14.

-> Difference of 4th and 2nd number is 1.

-> The 1st number is one less than twice the 2nd number.

->The 2nd number and the 3rd number equals 10.

->The sum of all digits is 30.

Crack the code ?

Not sure if it has already let me post, but:

74658

Spooky… looks like both answers are solutions. given the requirement on the riddle.

An additional clause could have been -> Each digit only appears once, which would make Max correct. Optionally it could have been -> Only a total of 4 different digits are used (Making Frank correct)

For the number-inclined, I know of a currently unsolved Halloween riddle

Well, if we’re collecting codes…

Some old DOS and UNIX computers required 8-digit passwords. I think this one would work:

Too much brain work to figure that one out…He just ran round and round the building until he was all in.

Max, you are today’s winner!

74658. * 8 + 6 =14. * 5 – 4 = 1. * 7 = 2*4 – 1. * 4 + 6 = 10. * 7+4+6+5+8 = 3074658
