Option 1 : 1

Given:

Total number of students in city A = 54

⇒ Total number of students in city B = 126

⇒ Total number of students in city C = 84

⇒ Total number of students in city D = 96

⇒ Total number of students in city E = 132

Ratio of students Passed and Failed in city A = 5 : 4 = 5 + 4 = 9

⇒ Ratio of students Passed and Failed in city B = 4 : 3 = 4 + 3 = 7

⇒ Ratio of students Passed and Failed in city C = 10 : 11 = 10 + 11 = 21

⇒ Ratio of students Passed and Failed in city D = 9 : 7 = 9 + 7 = 16

⇒ Ratio of students Passed and Failed in city E = 6 : 5 = 6 + 5 = 11

Percentage of passed students in city A = (5/9) × 100 = 55.55%

Percentage of passed students in city B = (4/7) × 100 = 57.14%

Percentage of passed students in city C = (10/21) × 100 = 47.61%

Percentage of passed students in city D = (9/16) × 100 = 56.25%

Percentage of passed students in city E = (6/11) × 100 = 54.54%

∴ in city C the percentage of passed students in less than 50%
