In a game of 100 points, A can give B 20 points and C 28 points. Then, B can give C:
8 points
10 points
14 points
40 points
Explanation:

A : B = 100 : 80.

A : C = 100 : 72.

 B = B x A = 80 x 100 = 10 = 100 = 100 : 90. C A C 100 72 9 90

B can give C 10 points.

We can use it in other way.

A:B:C = 100:80:72.

Here the question calculate the B can give C. So;
B:C =80 :72 ------B/C=80/72.

B is 100 points then C = 72B/80 here B = 100
C= (72 * 100)/80 = 90.

So, B can give C is = 100 - 90 = 10.

I have never seen a question like this before. How are you suppose to know how many points each person has at the beginning?

Sorry can't understand why you are writing (B/A*A/C) why don't write (A/B*A/C) or (B/A*C/A) is there any reason please tell me?

If we have to calculate for b/c then we should do b/a * a/c to cancel a.

I didn't get the 2nd last step.

Can anyone explain that?

How 10/9 became 100/90 why?

Why we multiplied 10/9*10/10?

Am getting 80/72 why is it 100/90?

From b:c we know 80-72 = 8.

i.e from 80 points b can give c 8 points.

In time and work problems we assume work is always one (1).

In the same way we have to calculate for 100 points in races topic because getting 100 points is the game winner.

For 80 b can give c 8 points.
For 100 b can give c 10 points.

Why 10/9 multiply by 10/10?
