In a class of students, R is older than S but younger than T. U is older than R but younger than V. Who is the youngest? (2023)

Step 1: Identify the relationships given in the question.
Step 2: From 'R is older than S', we know S is younger than R. So, we write S < R.
Step 3: From 'R is younger than T', we know T is older than R. So, we add R < T. Now we have S < R < T.
Step 4: Next, we look at U. The statement 'U is older than R' means U is older than R. So, we add R < U.
Step 5: The statement 'U is younger than V' means V is older than U. So, we add U < V. Now we have S < R < T < U < V.
Step 6: To find the youngest, we look at the order we created. The first person in the order is S.
Step 7: Therefore, S is the youngest.
