Correct Answer: 135


Solution : The number of students in the class interval 25–30 is 15.
The number of students in the class interval 30–35 is 20.
The number of students in the class interval 35–40 is 40.
The number of students in the class interval 40–45 is 50.
The number of students in the class interval 45–50 is 10.
$\therefore$ The total number of students in the class is 15 + 20 + 40 + 50 + 10 = 135
Hence, the correct answer is 135.
