  • Question
  • At a dinner party every two guests used a bowl of rice between them, every three guests used a bowl of dal between them and every four used a bowl of meat between them. There were altogether 65 dishes. How many guests were present at the party ?


  • Options
  • A. 60
  • B. 74
  • C. 82
  • D. 58

  • Correct Answer
  • 60 

    Explanation

    Let,

    no. of rice bowl = x
    no. of dal bowl = y
    no. of meat bowl = z

    Then, x + y + z = 65 ....(1)

    Also given that, 2x = 3y = 4z

    substituting value of y & z in terms of x i.e. y = 2x/3 and z = x/2 in eq (1),
    We get x = 30.

    As 1 rice bowl is shared between 2 guests,
    Therefore, there are 60 guests.
