In a game of carrom of 100 points, A can give B 20 points and C 40 points , then points B can give C is :
Answer & explanation
Correct answer: option 2
Total points of game $=100$.
A gives B $20$ points.
So when A scores $100$, B scores $80$.
Thus skill ratio:
$A : B = 100 : 80 = 5 : 4$
A gives C $40$ points.
So when A scores $100$, C scores $60$.
$A : C = 100 : 60 = 5 : 3$
Now combine ratios:
$A : B : C = 5 : 4 : 3$
Hence
$B : C = 4 : 3$
When B scores $100$, C scores $75$.
Therefore B can give C $25$ points.
The points B can give C is $25$.
