An intelligence agency decides on a code of 2 digits selected from 0,1,2....,9. But the slip on which the code is hand written allows confusion between top and bottom, because these are indistinguishable. Thus, for eg., the code 91 could be confused with 16. How many codes are there such that there is no possibility of any confusion?
- 75
- 25
- 80
