  • Question
  • In a game, A can give B 20 points, A can give C 32 points and B can give C 15 points. How many points make the game?


  • Options
  • A. 100
  • B. 200
  • C. 300
  • D. 400

  • Correct Answer
  • 100 

    Explanation

    Suppose, P points make the game.
    Clearly, when A scores P points, B scores (P - 20) points and C scores (P - 32) points.
    Now, when B scores P points, C scores (P - 15) points.
    When B scores (P - 20) points,
    C scores [( P - 15 ) / P * P (P - 20)] points
    ? (P - 15)( P - 20) / P = P - 20 or, P = 100
    Hence, 100 points make the game.
