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
