Question
There are three distinct numbers βpβ, βqβ and
βrβ. If, p = 150, (p + q) = 450 and (r β q) = 60, then determine the average of p, q and r.ΒSolution
ATQ,
Given,
p = 150, (p + q) = 450 and (r β q) = 60 Therefore, q = 450 β 150 = 300 And, r = 300 + 60 = 360 Required average = (150 + 300 + 360)/3 = 270
