5.

At a game of billiards, A can give B 15 points in 60 and A can give C to 20 points in 60. How many points can B give C in a game of 90?

 [A]. 30 points [B]. 20 points [C]. 10 points [D]. 12 points

Explanation:

A : B = 60 : 45.

A : C = 60 : 40.

 B = B x A = 45 x 60 = 45 = 90 = 90 : 80. C A C 60 40 40 80

B can give C 10 points in a game of 90.

 Habib said: (Sun, Mar 6, 2011 08:01:33 AM) A can give B 15 pts in 60...Then how come A:B=60:45????

 Priya said: (Sun, Sep 18, 2011 12:54:32 AM) @Habib Arey! The total points is 60 and from that he gives him 15. So 60-15 = 45

 Mukesh Vyas said: (Wed, May 23, 2012 07:49:31 PM) Please clarification 90/80 thus 45/60*60/40 for 9/8 but answer sheet for 90/80 please right clarification this question.

 Sowmya said: (Sat, Dec 1, 2012 12:59:33 PM) @Mukesh vyas. Solved it as 45/60*60/40 which gives the result of 45/40 i.e., in the form of ratio it is 45:40 means for 45 points he give 40 points. But here they asked for 90 points. So it got doubled i.e., 90/80 or 90:80. So we got the difference as 10 points which is our required answer.
