i am a four -digit number with no two digits the same. my ones digit is twice my thousands digit and one less than my tens digit. my hundreds digit is the difference between my tens digit and my thousands digit. my thousands digit is an odd number less than 6.
what number am i?
This is best posted in the riddle section.
i think i have posted it but i can't see it on the site
let the number be abcd
a<6 and odd, so a = 1,3,or5
no two digits are the same
rule out a=5 because then d=10, not possible
let a=1, then
b=2, but that would be two digits the same
let a=3, then d=6
the number is 3476
3476 makes sense!
