Heya !!!
Let the number of students in school be X.
Number of girls = 5/8 of X = 5X/8
Number of boys = Total Number of students - Number of Girls = X - 5X/8 = 8X - 5X/8 = 3X/8.
According to question,
Number of girls = Number of boys + 120
5X/8 = 3X/8 + 120
5X /8 = 3X + 960/8
5X×8/8 = 3X + 960
5X - 3X = 960
2X = 960
X = 960/2 = 480
Total Number of students in school = X = 480 students.
Number of boys = 3X/8 = 3 × 480/8 = 180
