Best answer
Correct Answer - Option 1 : 38.09%

GIVEN:

⇒ Total students = 350

⇒ Girls = 40% of Total students

⇒ Boys = 60% of Total students

Total Passed = 240 Students

Girls passed = 110

CALCULATION:

Total students = 350

Girls = 40% of 350 = 140

Boys = 60% = 210

Total Passed = 240 Students

Girls passed = 110

Boys passed = 130

Boys failed = Total boys - Boys Passed

Boys Failed = 210 - 130

Boys failed = 80

Boys failed percent = (80/210) x 100

Boys failed = 38.09%

∴ the correct answer is 38.09%
