So I've noticed that many people here haven't been making their minds, "active", lately because of summer, so I decided to make a challenge.

Solve a problem and earn 10 PC. Fee is 1 PC. Don't bother searching it up, since it won't show up. I will do more of these if once I see how smart people around here are, and see how high to increase the PC :p (Cause I don't want to drain all my pc ;-; ) I will give anybody a "hint" for 2 PC in a PM if you need it. Please do not use Yahoo answers or something like that, if I find out you are disquailfied. If you have any questions, please ask.

Also, IMPORTANT:
Only the first one to get it gets pc. Sorry, bout that.

Say your answer in a PM, please.

Fee: 1 pc
Reward: 10 pc
Deadline: 7/13 or 7/14 we will see
Hints: 2 PC, each. Max of 2
Limits of tries: 5
OVER


Problem:
A brown bottle contains a concoction that is 20% orange juice. A red bottle contains a concoction with an unknown amount of orange juice. An equal amount of both bottles is poured into an empty jug. If the resulting mixture has an orange juice concentration that is 30% greater than the orange juice concentration of the brown bottle, what percent orange juice did the red bottle originally contain?

There are two ways to do it, I'm going to do it this way:
Credit goes to: satellite73
Say each has 100 liters, the brown bottle has 20 liters, of orange juice, the brown one unknown liters of orange juice. (that is what we are trying to find)

When you mix them together, you have 200 liters total so 26 percent.

It's 26% because the concertation is 30% greater than the brown=23% of orange juice.
Then 23% is the average of the brown and the red (29%), so it is 26% for the red flask.

26% of 200 is 52 so there are 52 liters of orange juice total. 20 liters came from the brown flask, the other 32 liters came from the red flask.

So the red flask had 32 liters or 32%.
