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
Answer: Option
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.

Why multiple 10/9 with 10?

@All.

In 100 point game b gets only 80 point and C gets 72 point.
Where B gets 80, C can get 72 point, here at this time B gets 80 points but in our question, we need to calculate for 100 points.

WIn 80 point game B beat C by 8 point.
Then in 100 point game B beat C by 10 point.
80---------8
100-------?

(100*8)÷80=10.

How 10/9 became 100/90?

Why 10/9 multiply by 10/10?

Couldn't understand the problem? What is being asked and what to solve?

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.
