Mathematics:
Total number of students = 240 [From previous question]
Number of boys = 150
Number of girls = 240 – 150 = 90
Difference between number of boys and girls = 150 – 90 = 60
Chemistry:
Total number of students = 340
Number of girls = 3/5 × Total = 3/5 × 340 = 204
Number of boys = 340 – 204 = 136
Difference = 204 – 136 = 68 students
Statistics:
Total number of students = 320
Number of girls = 250
Number of boys = 320 – 250 = 70
Difference = 250 – 70 = 180
Physics:
Total number of students = 300
Number of boys = 60/100 × 300 = 180
Number of girls = 300 – 180 = 120
Difference = 180 – 120 = 60
∴ Difference is same (60) for Mathematics and Physics
