For 200 candidates of an exam in Delhi, the less-than ogive gives cf = 50 at marks 30 and cf = 150 at marks 60. Using the upper-quartile idea, the marks where cf = 150 (= 3N/4) represent which measure?

Third quartile Q3. 3N/4 = 3 × 200/4 = 150. The mark where cf = 150 is the upper (third) quartile Q3.
