Answer:
a) 48 girls
b) 80 students
c) 45 boys
Step-by-step explanation:
Total no. of students = 120
Fraction of students which like maths = 2/3
Amount of students which like maths = 2/3 * 120 = 80
No. of girls which like maths = 35
No. of boys which like maths = 80 - 35 = 45
Total no. of students which are boys = 3/5 * 120 = 72
No. of girls = 120 - 72 = 48
