Answer 1

Answer:

pls mark my answer as brainlist

Step-by-step explanation:

Let the rational between number of boys and girls be x

Thus the number of girls was 4x and number of boys were 3x

There were 36 girls. As such

4x = 36

x = 36/4

x = 9

The rational is 9, therefore

Number of girls 4x = 4 × 9 = 36

Number of boys 3x = 3 × 9 = 27

Total students = 36 + 27 = 63 students

Thus, there were 27 boys in the class

Answer there were 27 boys in the class

Answer 2

Step-by-step explanation:

Total number of students in the class=36

Number of girls in the class =x

Number of boys in the class=2x

x+2x=36

3x=36

x=12

Number of girls=12

Number of boys 2x=24

Sarita's rank in the class is 19th. There are 13 boys ahead of her. Therefore, there are 5 girls ahead of her.

Therefore, number of girls behind sarita 12−5−1=6
