  • Question
  • Out of three numbers, the first is twice the second and is half of the third. If the average of the three numbers is 56, what will be the sum of the highest number and the lowest number?


  • Options
  • A. 120
  • B. 160
  • C. 80
  • D. 60

  • Correct Answer
  • 120 

    Explanation

    Let the three numbers be x, y, z.

    From the gien data,

    x = 2y ....(1)

    x = z/2 => z = 2(2y) = 4y .....(From 1)  ...........(2)

    Given average of three numbers = 56

    Then,

     

    x   +   y   +   z 3   =   56 2 y   +   y   +   4 y 3   =   56     ( From   1   &   2 ) 7 y   =   56   x   3 y   =   24

    Now,

    x = 2y => x = 2 x 24 = 48

    z = 4y = 4 x 24 = 96

     

    Now, the highest number is z = 96 & smallest number is y = 24

     

    Hence, required sum of highest number and smallest number

    = z + y

    = 96 + 24

    = 120.
