Let total no. Of students in school = x
Let total no. Of students who took science = s

Given that : 80 + x/3 = s

Let no. Of students who took chemistry = c

S/3 = c
x/6 = c
So while solving , x = 2s
While substituting the value of s in the equation 80 +x/3=s

We get ,x = 480
Hence answer will be 480
