Answer 2

Answer : The Third Quartile (Q3) is 32.5 Step-by-step Explanation : Given : first quartile (Q1) = 12.5 Quartile Deviation (Qd) = 10 To find : Third Quartile (Q3) = ? We know that, Quartile Deviation (Qd) = Q3 - Q1 / 2 Substituting the given value in above formula we get, 10 = Q3 - 12.5 / 2 10 × 2 = Q3 - 12.5 20 = Q3 - 12.5 20 + 12.5 = Q3 Q3 = 32.5 Hence the Third Quartile (Q3) is 32.5
