- The ratio of boys to girls in the school is 5:7.

- This means for every 5 boys, there are 7 girls.

- Let’s express the number of students in terms of this ratio: \(5k\) boys and \(7k\) girls, making the total \(12k\) students.

- The total number of students must be a multiple of 12.

- Option 1: 1440 is divisible by 12 (1440 ÷ 12 = 120).

- Option 2: 1442 is not divisible by 12.

- Option 3: 1502 is not divisible by 12.

- Option 4: 1441 is not divisible by 12.

1440 is the only option that fits the requirement.
