  1. Out of three numbers, the first is twice the second and is half of the third. If the average of three number is 56, the three number in order are ?

    1. 48, 96, 24
    2. 48, 24, 96
    3. 96, 24, 48
    4. 96, 48, 24
  1. Correct Option: B

    Let second number = x
    So, first number = 2x and third number= 4x
    ∴ ( x + 2x + 4x ) / 3 = 56
    ⇒ 7x = 168
    ⇒ x = 24
    So the numbers are 48,24, 96,
