lets first write down the numbers which follow "digit in unit's place is 2 more than ten's place"
13
24
35
46
57
68
79
it cant be any number which ends with an odd number, the difference wouldnt be 37 then. it narrows down to
24
46
68
the number should also be the multiple of an odd number, other wise the difference wouldnt be odd, it would be even
this leaves us with the only answer
46, you can then confirm it
4*2 = 8 , 6/2 = 3
83-46 = 37
