Answer:

270 students

Explanation:

There are more boys than girls, as the ratio of boys to girls is 4:5.

Write and solve an equation of ratios:

4 5

-------- = --------

120 g

... where g is the number of girls. Cross multiplying, we get:

4g = 600, so that g must be 150.

120 boys plus 150 girls comes to 270 students (Answer d)
