In a class three subjects, English, Science and Mathematics are taught. It is known that 25% students like Mathematics, 60% students like English and 45 students like Science. If each student likes only one subject, then find the total number of students in the class.

Correct option is D

Given:
Students who like Mathematics = 25%
Students who like English = 60%
Students who like Science = 45 students
Formula Used:
Total percentage = 100%
Total students = $$\frac{Value}{\%}$$​ × 100
Solution:
Since each student likes only one subject, the sum of their percentages must equal 100%.
Percentage of students who like Science = 100 - (25 + 60)
Percentage = 100 - 85 = 15%
We know that 15% corresponds to 45 students.
Let the total number of students be x.
​$$\frac{15}{100} × x = 45$$​​
x = $$\frac{45 × 100}{15}$$​​
x = 3 × 100 = 300
The total number of students is 300.
Final Answer
So the correct answer is (d)
