Can someone help clarity -

No of terms in set A AND set B is 3. Total number of terms is 33. How do we make out the distinction between total no of terms in A and B versus just the intersection of terms that are common?

what do you mean? I don’t understand your question

The nuance between the AND number of terms and total number of terms for Set A and B. How do you make the distinction?

Initially I marked down the answer as 3 since three terms are common (30, 60, 90). But the answer was 33 which was the total number of terms without repeats.

Hi srushti! So we are considering 33 because the question asks, "what are the total number of terms of terms in Sets A and B?’. The key word here is “total”. That’s why we are considering all the terms that are in set A + set B(Set A and B total). If they wanted us to find out the intersection(AND), the question would have been something like,“which terms set A and set B have in common?”.
