Answer 2

Answer:

Option C- 60%

Step-by-step 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

$\Rightarrow \frac{111}{184}\times100=\frac{11100}{184}=60.32$

Percentage is approx. = 60%

Therefore, option C is correct
