    Question

    Three numbers ‘A’, ‘B’ and ‘C’ are such that

    ‘A’ is half of ‘B’ and ‘C’ is equal to average of ‘A’ and ‘B’. If sum of these three numbers is 540, then ind the second highest number among the three. 
    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 ‘B’ be ‘2x’ So, value of ‘A’ = 2x/2 = ‘x’ So, value of ‘C’ = (2x + x)/2 = 3x/2 = ‘1.5x’ ATQ; x + 1.5x + 2x = 540 Or, 4.5x = 540 Or, x = 120 So, the second highest number = ‘C’ = 1.5x = 1.5 × 120 = 180
