Hello Veritas Experts,

I was going over a few mixture problems and came across a neat equation which VeritasKarishma uses. Wanted to learn this better and followed the blog link which she had posted, but the link is broken.

Can someone please help me with the correct link?

The links are correct. Our blog was facing some technical glitch for the past few days. All is sorted now.

Hi Karishma,

Can you show how to use the weighted scale approach on this question? I've tried a few ways and I don't believe I'm doing it correctly. https://gmatclub.com/forum/a-rabbit-on- ... l#p2635712

I am not Karishma, but this is how I would use weighted average for this question.

We know X is 10% and Y is 15% protien. Final mixture has 38 grams of protein in 300 gms.

10% = 10/100 can be written as 30/300 and 15% = 15/100 = 45/300

-------------- X --------------------300-X
30/300 ------------- 38/300 -------------- 45/300

(38-30)/(45-38) = (300-X)/X

Solving this for X, gives X = 140g.

Hope this helps.

Very helpful. Thanks. Must you always convert the percentages? I got stuck by trying to scale 10 and 15.

No, we need not convert every time. It depends on how the other values are expressed. In this question, we had the target given as 38g for every 300g. So, to make the calculation easier, I expressed the percentages in fractions and made the denominator 300. If the target was given as say 12%, then I would keep the percentages as is.
