Study the following table and answer the questions. Classification of 100…

Concept

In a cumulative "marks and above" frequency table, each column entry already counts every student scoring at or above that mark. So the number of students meeting a given percentage cutoff is read directly from the column whose header equals that cutoff mark - it is never obtained by adding or subtracting entries from other columns.

Application

1. Convert the eligibility rule into an absolute mark: 60% of the maximum 50 marks = (60/100) × 50 = 30 marks.

2. The question asks specifically about Physics, so the Physics row of the table is the only one relevant.

3. Locate the column headed "30 and above" - this matches the 30-mark cutoff exactly, so no interpolation between columns is needed.

4. Read the Physics-row value under that column: 32 students.

Cross-check

Cumulative counts must fall as the threshold rises. For Physics: 100 (0 and above) ≥ 92 (10 and above) ≥ 80 (20 and above) ≥ 32 (30 and above) ≥ 9 (40 and above). The value 32 sits consistently in that decreasing sequence, confirming it was read from the correct row - unlike the Chemistry and Average rows, whose own 30-and-above entries (21 and 27) belong to a different sequence entirely.
