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!

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?

Hi Iliavko,
You can go through the below link to get a fair idea about the mixture concept and where it can be used.
