if there are 4x boys, there are 6x girls.

4x+6x=54

10x=54

x=5.4

so, there are 21.6 boys and 32.4 girls.

a strange solution. Are you sure there was no mistake in the question as written?

Unless, of course, not all the boys and girls are pupils.

If the answer is 24, then there must have been 60 pupils in the class. 24 boys, 36 girls.
