the number is 48.

The answer is D

If you look at the choices you're given, and you know that two numbers have to add up to 12, then it can't be B or C, because it would have to be 1 + 11 or 2 + 10, and you only have 1-digit numbers to work with, so it's either 4 or 8.

84 doesn't make sense, because 12 x 8 = 96, so it has to be 48
