Answer 2

Option C- 60%

Explanation:

Given :

Gender : Grade 9 Grade 10 Grade 11 Grade 12

Male: 53 19 27 37

Female: 31 42 50 61

To find : Percentage of females are in grades 11 and 12

Solution: Total number of females= 31+42+50+61= 184

Number of females in grades 11 and 12 = 50+61 = 111

Percentage of females are in grade 11 and 12 = (No. of females in 11 and 12/total no. of females) × 100

`\Rightarrow (111)/(184)*100=(11100)/(184)=60.32`

Percentage is approx. = 60%

Therefore, option C is correct
