Hi everyone!
A question on weighted av and mixture questions! First of all should I even bother? mixtures are very exotic questions and they are a pain. Should I spend time on these?
I have read (from @Karishima) that the weighted average concept will allow to easily solve the mixture questions AND it is also useful for other question types.
Question: which questions can weighted av concept help me with? How can I learn the mix questions and is it useful?..
Suggestions welcome!

Dear iliavko,
I'm happy to respond.
Yes, not surprisingly, the genius Karishma is right: if you understand weighted averages, it can help with mixtures and many other ideas.
It's true that mixtures are a rare question on the GMAT. I will say, though, once you understand them, they are quite straightforward: there aren't many tricky variations the test could devise.
Here's a blog about mixtures. Basically, you just need to understand two equations: the total volume equation and the concentrate equation.

Here's a blog about weighted averages: this definitely is worth knowing, because it applies to many different things on the GMAT.

Does all this make sense?
