Question

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

• A. 30 points
• B. 10 points
• C. 20 points
• D. 12 points

Answer 1

Answer:

B. 10 points

A can give B 15 points in 60 means in a game of 60 points A has to score 60 points where B needs to score only 60 – 15 = 45 points. ⇒ A: B = 60: 45 Similarly A can give C 20 points in 60 ⇒ A: C = 60: 40 B: C = 45: 40 = 90: 80 In a game of 90, B can give (90 – 80) = 10 points to C
