Question
There are three distinct numbers ‘x’, ‘y’ and
‘z’. If, x = 180, (x + y) = 480 and (z – y) = 60, then find the average of x, y and z.Solution
Given, x = 180, (x + y) = 480 and (z – y) = 60Therefore, y = 480 – 180 = 300And, z = 300 + 60 = 360Required average = (180 + 300 + 360)/3 = 840/3 = 280
