    Three numbers β€˜A’, β€˜B’ and β€˜C’ are such that

    β€˜A’ is half of β€˜B’ and β€˜C’ is equal to average of β€˜A’ and β€˜B’. If sum of these three numbers is 540, then ind the second highest number among the three.Β 
    A 180 Correct Answer Incorrect Answer
    B 104 Correct Answer Incorrect Answer
    C 120 Correct Answer Incorrect Answer
    D 134 Correct Answer Incorrect Answer

    Solution

    Let the value of β€˜B’ be β€˜2x’ So, value of β€˜A’ = 2x/2 = β€˜x’ So, value of β€˜C’ = (2x + x)/2 = 3x/2 = β€˜1.5x’ ATQ; x + 1.5x + 2x = 540 Or, 4.5x = 540 Or, x = 120 So, the second highest number = β€˜C’ = 1.5x = 1.5 Γ— 120 = 180
