Answer :

A) Systolic blood pressure in the normal range = 120mm Hg


Diastolic blood pressure in the normal range = 80mm


Approximate ratio of systolic to diastolic blood pressure =


=


=


ratio = 3:2


B) Manohar’s systolic blood pressure = 102mm Hg


Let diastolic blood pressure = x mm Hg


Approximate ratio of systolic to diastolic blood pressure =


=


x =


X = 68mm Hg


C) Average systolic blood pressure in prehypertension category =


= mm Hg


Average diastolic blood pressure in prehypertension category =


= mm Hg


Hence, ratio of average systolic to average diastolic blood pressure =


= =


=


Ratio is 259:169
