A two-digit even number is such that reversing its digits creates an

E

A.B a two digit number
For this number to be even, B must be even

reversing its digits creates an odd number
B.A the reverse has to be odd

Means A must be odd

A is the 1st number must be odd (1;3;5;7;9)
B must be even (2;4;6;8;0)
0 has to be excluded because reversing an 2 digit even number with 0 become an 1 digit number and the reverse can never be greater that the previous.


We have to find a number that while reversing will not satisfy the requirements
A has to be at it maximum and B at it minimum 0
As 0 has to be excluded the maximum value of A will then be considered

As we have a list of 1 digits (1,- ,-,-,9)


For A at it maximum
A.B = 98 —->> B.A =89 << 98
94—->> 49
96 ——->>. 69
