Hi vblinks,

Is this a question form a "math" class or is this a question from a GMAT course?

This is clearly not a GMAT-style question. For one, the wording is terrible. For another, the GMAT will not ask you to solve 2-part questions on the Quant. Please do not post non-GMAT questions!

If you're struggling with the structure of the Venn diagram, though, it would look like this:

Since 8 + 22 + 3 + 5 = 38, then 2x + M must equal 2. This means that either x = 1 and M = 0 (which is likely what is implied), or x = 0 and M = 2.
