Question

    The average of two numbers ‘U’ and ‘V’ is 420 such

    that they are in the ratio 4:2 respectively. Another number ‘W’ is 180 more than ‘V’ and fourth number ‘T’ is 75% of the ‘U’. Find the average of ‘W’ and ‘T’.
    A 430 Correct Answer Incorrect Answer
    B 435 Correct Answer Incorrect Answer
    C 440 Correct Answer Incorrect Answer
    D 445 Correct Answer Incorrect Answer
    E 450 Correct Answer Incorrect Answer

    Solution

    Sum of ‘U’ and ‘V’ = 420 × 2 = 840
    Therefore,
    ‘U’ = 840 × (4/6) = 560
    ‘V’ = 840 – 560 = 280
    ‘W’ = 280 + 180 = 460
    ‘T’ = 0.75 × 560 = 420
    Required average = {(460 + 420)/2} = 440
