Video Summary

The class has <strong>25 students</strong>.

Here’s the reasoning in brief:
- Let the number who like <strong>French only</strong> be \(x\).
- The number who like <strong>both</strong> is also \(x\).
- So the total who like French is \(2x\).
- The number who like <strong>math</strong> is twice that, so \(4x\).
- Since math includes the both group, math only is \(3x\).

Total students:
\[
x + x + 3x = 5x
\]
So the class size must be a multiple of 5 between 23 and 29, which is <strong>25</strong>.
