Anita's mathematics test had 70 problems carrying equal marks i.e., 10

1.	Anita's mathematics test had 70 problems carrying equal marks i.e., 10 arithmetic, 30 algebra and 30 geometry. Although she answered 70% of the arithmetic, 40% of the algebra and 60% of the geometry problems correctly, she did not pass the test because she got less than 60% marks. The number of more questions she would have to answer correctly to earn a 60% passing marks is:1. 12. 53. 74. 9
Answer» Correct Answer - Option 2 : 5 Given Total Questions = 70 Formula Used Percentage = (Actual/Total) × 100 Calculation Question correctly by anita as follow: ⇒ Airthmetic = 70% of 10 = 7 ⇒ Algebra = 40% of 30 = 12 ⇒ Geometry = 60% of 30 = 18 ⇒ Total correct Question by anita = 37 ⇒ For pass no. of Question should be correct = 60% of 70 = 42 ⇒ Number of more questions she would have to answer correctly to earn a 60% passing marks = 42 - 37 = 5 ∴ Number of more questions she would have to answer correctly to earn a 60% passing marks is 5.

Answer» Correct Answer - Option 2 : 5

Given

Total Questions = 70

Formula Used

Percentage = (Actual/Total) × 100

Calculation

Question correctly by anita as follow:

⇒ Airthmetic = 70% of 10 = 7

⇒ Algebra = 40% of 30 = 12

⇒ Geometry = 60% of 30 = 18

⇒ Total correct Question by anita = 37

⇒ For pass no. of Question should be correct = 60% of 70 = 42

⇒ Number of more questions she would have to answer correctly to earn a 60% passing marks = 42 - 37 = 5

∴ Number of more questions she would have to answer correctly to earn a 60% passing marks is 5.
