If n is a positive integer, what is the tens digit of n?
1. The hundredths digit of 10n is 6
2. The tens digit of n+1 is 7
For the second statement I thought that the number could have been 69 or numbers from 70 to 79.So i knew that we are not getting a single value,hence I chose A, which is correct?
I want to know how A is correct?

You can, for example never foretell what any one man will do, but you can say with precision what an average number will be up to!
