"I need to calculate this.

There are two sections A and B. A is 150 points, B is 200 points. Both A and B count for 50% of the total exam.

This would mean that each A point is worth 4/3=1.33 and each B point is worth 1. This is the given formula.

Since each A point is worth more than a B point, I want to calculate what % of the total points each A point is worth.

Because an A point is not equal to a B point.

They just keep saying A points are 4/3 the points of B, but it's easier for me to know how much to devote based on %. As in what the true % of each A and B point is relative to the entire exam.

Thanks very much."

If you scored 150 in A - you would get 50 points. So each point of A is worth 1/3.

If you scored 200 in B - you would get 50 points. So each point of B is worth 1/4.

Now continue....
 
Hi, thank you for that quick reply. My head hurts so much from trying for the past 4 and half hours.

I don't get it. If A is worth 1/3 (this was 50/150), and B is 1/4 (50/200) then this means 33% and 25%? Or A is worth 66% and B 33%? I'm so confused.
 
Is this correct -

Okay each A point is 1.33 and each B point is 1.
So A is 33.33% more than B.
100% - 33.33% = 66.66

Then divide the 66.66 / 2 = 33.33

Then add to A 33.33+33.33 = 66.66 for total of A.
And B is 33.33.

Answer:
A = 66% of total exam.
B = 33% of total exam.

Can this really be true is seems like a lot is attached to A. Because in the formula it is like this:

(Essay (A) x 4/3) + Multiple Choice B = Score
2

Essay is out of 150,
Multiple Choice is out of 200

Thanks again.
 
I am not sure what you are trying to do.

If it is a problem that appears on book (or given in class) - please post its exact wording.
 
Sorry about that confusion.

Here is what I am trying to do:

I am taking an examination and in the exam there are two portions. The Essay and the Multiple Choice. There are 15 essay questions, each worth 10 points, for a total of 150. There are 200 Multiple Choice questions, each worth 1 point, for a total of 200 points.

The formula they use to calculate whether you pass or not is

[ [(Essay total x 4/3) + Multiple Choice total] / 2 ] = Passing Score

I am trying to allocate a percentage to the Essay relative to Multiple Choice. Hope this makes sense. Thanks.
 
That's what I didn't get either. At first I took it to mean that if you score 50%, but then A is worth more than B. :? What do you think of the rest of it (the parts I worked out), I still don't know if I am right or wrong.

Edit to add: I wrote this to a reply from another member, but not the post is deleted so I guess we can ignore it.
