AI-generated practice question — model-generated for extra practice, not a previous-year CBSE board question.
The normal systolic blood pressure is 120 mm of Hg and the normal diastolic blood pressure is 80 mm of Hg.

The examiner expects both values stated clearly with correct units (mm of Hg). Remember: systolic = pressure during ventricular contraction; diastolic = pressure during ventricular relaxation. A common error is omitting the unit or swapping the two values. For 1 mark, simply stating both figures correctly is sufficient.
