### Answers and Explanations

**Explanation for questions 1 to 3:** There are four cases as a result from the given information

These are the four possible cases where three of his appointments can be scheduled.

**Answer 1 : (d)**

Dilip can take a 3 hour Thyroid checkup on any of the four days as a three hour time slot is available on each of these days. Remember to keep all the four cases in mind while solving this question.

**Answer 2 : (d)**

Considering the given information in the question, we can see that only cases 3 and 4 are applicable here. Option (a):From case 4, Dilip can take a Cardiograph checkup from 1 pm to 3 pm Option (b): From case 3 and 4, we can see that the Thyroid check-up is not impacted by the tests on Sunday. Hence, the statement is correct. Option (c): We can derive this from case 3. Thus, all the statements are possible.

**Answer 3 : (b)**

Thyroid checkup is always in the first half (ruling out options a). Cardiograph checkup takes place in the second half only (ruling out option c). In all 4 cases, appointment for the Skin checkup can be taken in the second half, and the Thyroid checkup takes place in the second half. So, the correct answer would be option b
