Answer 2

Answer:

Step-by-step explanation:Let the number of boys be x

number of girls = 2/5x

Total number of students = 35

Number of girls + number of boys = 35

=> 2/5x + x = 35

=>( 2x + 5x)/5 = 35

=> 7/5x = 35

=> x = 25

Number of girls = 2/5 * 25 = 10

Therefore there are 10 girls in the class.
