Hope this helps ;)

Aim: total number of students

1) Represent B in terms of A

2) Total number of students in terms of A

3) Fraction: put number of boys in Class B in terms of 2/5 A so that we can cancel out the A from numerator and denominator at the end

Alternative is to put all in terms of B and cancel B at the end
