The Average Of Three Numbers Is 77.the First Number Is Twice The Second And The Second Number Is Twice The Third. Find The First Number?

Answer»

Here as per condition let us CONSIDER THIRD number = X,

then 2nd number = 2x and 3rd number = 4X,

Given that (4x+2x+x)/3 = 77,

7x = 3×77, x = 3 x 11 = 33,

FIRST number = 4x = 4 x 33 = 132.
