Hey mate
Here is your answer :--

Let common multiple be x
So, the number of boys in class = 4x
and the number of girls in the class = 5x

According to given condition :-
4x + 5x = 54
9x = 54
x = 54/9
x= 6

So, number of boys in class :- 4x = 4× 6 = 24
and number of girls in the class :- 5x = 5×6 = 30


Final answer :- Number of boys and girls in the class are 24 and 30 respectively


Hope this help you mate and if you have any more queries just let me know in the comments
