Answer:

2000 students  (840 are girls and 1160 are boys)

Step-by-step explanation:

Let X be the total number of students.  Let G and B stand for the total number of Girls and Boys, respectively.

We are told that 58% are boys:

0.58X = B

This means 42% are girls:

0.42X = G

We are told that G = 840

0.42X = 840

X = 2000 students

====

Since 0.58X = B

0.58(2000) = 1160 boys

1160 boys

840 girls

2000 total students
