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
