Show answer & explanation
Correct answer: A
Concept: To find what percentage a group of categories forms of a grand total, add the frequencies of the required categories, divide that sum by the grand total, and multiply by 100.
Identify the enrollment ranges below 120 from the table: 20-39, 40-59, 60-79, 80-99, and 100-119.
Read off their frequencies: 526, 620, 674, 717, and 681 schools respectively.
Sum these frequencies: 526 + 620 + 674 + 717 + 681 = 3218.
Divide by the grand total of schools given in the table (5439) and multiply by 100: (3218 / 5439) × 100 ≈ 59.16%.
Cross-check: 3218 is close to 59% of 5439 (since 59% of 5439 ≈ 3209), confirming the share is near 59%, not 60% (which would need about 3263) or 61% (about 3318).
