40
Given,
Total students in the class = 40
Total Hindi speaking students = 25
Total both language speaking students = 15
To find,
Total number of students who only speak English.
Solution,
We have to keep in mind the following mathematical equation.
Total students = Only Hindi speaking students + Only English speaking students + Both language speaking students
Now, we have to calculate the number of only hindi speaking students.
Only Hindi speaking students = Total Hindi speaking students - Both Hindi and English speaking students = 25-15 = 10
Only English speaking students =
Total students - (Only Hindi speaking students + Both language speaking students) = 40 - (10+15) = 40-25 = 15
Hence, 15 students speak only English.
