my work:

Number of Boys = B

Number of Girls = G

G = B

We know that the number of girls was 4 times more after 108 boys left.

For boys:

-------------------------------------------------------

G = 4(b-108).

And since we know G = B

B = 4(B - 108)

B = 144.

------------------------------------------------------

For girls

-----------------------------------------------------

Then I plugged it back in G = 4(B - 108)

so, G = 4(144 - 108)

G = 4(36) = 144.

---------------------------------------------------

Total number of students is 144 + 144 = 288.
