    2B is not 20 + B, in general. They can only be equal if B=20.

    299 is evenly divisible by the integers 13 and 23 only. If 2B is 13 or 23, B cannot be an integer. None of the multiple choices are correct.

    From the original question (not posted here) it was clear that 2B means 20 + B here, because B was referred to aa a digit. Also, as drwls pointed out, the question doesn't make sense if 2B is interpreted as 2*B

    As I replied below, from the fact that 23 is a divisor, you can read off that B = 3.
