Let the number be \(b\) and \(g\), so total students = \(b+g\).

Now, the number of boys (\(b\)) exceeds the number of girls (\(g\)) by one-fourth of the total number of students in the class ( \(\frac{g+b}{4}\)), so \(b=g+\frac{g+b}{4}.......4b=4g+g+b......3b=5g....\frac{b}{g}=\frac{5}{3}\)

We can let b = the number of boys and g = the number of girls in the class. Thus, the total number of students in the class is (b + g). We can create the equation:

b = 1/4(b + g) + g

4b = b + g + 4g

3b = 5g

b/g = 5/3

Let,
total no of students(b+g) = 8

boys exceeds girls, i.e, b - g = 1/4 of 8 = 2

Now, we have, b + g = 8....... (1) & b - g = 2.....(2)
(1) + (2) => b+g+b-g = 8+2.... hence, b = 5 & g = 3
Therefore, b:g = 5:3

Kudos, if you found it helpful✌✌✌
