Explanation:
It is a very simple puzzle to answer.
As the average height of the four-person is 74 inches then the Total height of all of them will be 74 x 4 = 296 inches.
Let the height of the 3rd person be x and let’s consider the heights of all the people in increasing order.
As per the question, the First person’s height will be (x – 4),
2nd person’s height will be ( x – 2)
And 4th person’s height will be ( x + 6)
Now, Adding all we get ( x -4 ) + ( x -2 ) + x + ( x + 6) = 296
Or, 4x = 296
Or, x = 74
Hence, the heights of the brothers are 70 inches, 72 inches, 74 inches, and 80 inches.
