The only thing you need to do for probability questions on GMAT is learn the basic definition of probability and practice different types of probability problems. The internet is obviously the best place to find lots of probability problems.

Then I took the average of the smallest num...

Actually just read the question again. It is pretty simple. The only thing to note is that for a set of consecutive integers the median is same as the mean. Use this and the solution is pretty simple.

Here's the answer: (1) SUFFICIENT: We can rewrite this equation in a base of 3: 3b + 2 = 34, which means that b + 2 = 4 and therefore b = 2. We can plug this value into the equation a = 3b – 1 to solve for a. (2) SUFFICIENT: We can set the right side of this equation equal to the right side of the ...
