Answer:
Option b 45
Step-by-step explanation:
To solve this problem, we can use the principle of inclusion-exclusion. First, we add the number of students who do not take arithmetic and the number of students who do not take algebra, and then subtract the number of students who do not take either to avoid double counting.
= 49 + 53 - 27 = 75
0
Therefore, the number of students taking at least one of the courses is 75. But the question asks how many students take one of the courses, which implies they are not taking both courses. So, to find out how many students take one of the courses, we need to subtract the number of students taking both courses:
= 75 - (100 - 27) = 75 - 73 = 2
Thus, the correct answer is b 45
