Given:
In a class of 150 students, 45 take history, 65 take geography and 10 take both history and geography.
To Find:
How many students take at most one subject?
Solution:
We know that,
Total students in a class = 150.
No. of students who take History = 45.
No. of students who take Geography = 65.
No. of students who take both history and geography = 10.
So,
No. of students take at most one subject = 150 - 10 = 140.
Hence, 140 students take at most one subject.
