2 answers:
13,14,15,31,34,35,41,43,45,51,53,54 so 12
We have 1, 3, 4 and 5
All are distinct numbers.
To form a two digit number, we have two places to fill with digits: _ _
The first place can be filled in 4 ways.
The second place can also be filled in 4 ways as repetation is allowed.
So total number of ways = 4×4 = 16
You can form 16 two digit numbers.
