Hey Bull.

Whats this Mattean triangle?

I don't even know how to spell this?

Whats the source? Are you sure that it was GMAT based?

lol. GMATBULL has added the source on the top.

Veritas prep, itseems.

I guess they could ask questions this way. This is like those questions with special symbols where the define the operation for that symbol and ask to find the specific output for the given input values .

Another one that I could think of and that I came across in GMAT prep is below...

For any positive integer n, the length of n is defined as the number of prime factors whose product is n. For example, the length of 75 is 3, since 75 = 3 x5x5. How many two digit positive integers have length 6?

A)None

B)One

C)Two

D)Three

E)Four

Happy learning
