Thanks

i did not understand even a single strategy .. would you please simplify any one of them with the image structure??

I'll break down the first question for you.

My personal opinion is that a time line is easier than 4 arrows, but that's just a preference.

(1) Consider a straight line (see image below)

(2) Put the respective ratios on each side of the spectrum

(3) Put 45% between "30" and "50" (the goal of the solution is to mix 30% and 50% and get 45%, right?)

So, 45 is somewhere between 30 and 50. How far is 45 from 30? 15 "steps"

How far is 45 from 50? 5 "steps"

Now, to find the ratio, you simply flip the respective number. 15:5 becomes: 5:15 or simplified to 1:3. So, you use 1 "part" of 30% and 3 "parts" of 45.

Hope this explaination helps

once you get the hang of these questions and practice a few they are pretty straightforward. The trick is trying to work out what the question is getting at!

one of the best posts on the website - thanks a lot. This makes these problems like child's play. I wouldn't be surprised if some company TMs this technique if hasn't already.

Quick question.

In the Example 5, the explanation says that the volume of the new solution is x/2. If one amount of solution replaces the same amount, how is the volume of the new solution cut in half? If I take out 1 liter of solution and replace it with 1 liter of another solution, my overall volume stays the same. Could someone please explain the assumption that the volume is x/2.

Thanks!
