Question

Who is the first student to start writing the assignment?

• A. E-1
• B. E-2
• C. E-3
• D. Cannot be decided
• A. E-1
• B. E-2
• C. E-3
• D. Cannot be decided

Answer 1

The Correct Option is C

To solve this problem, we need to analyze the given information logically:

• The students E-1, E-2, and E-3 each start and complete their assignments at different times.
• The number in their designation (E-1, E-2, E-3) is not the same as their order of starting or completing the assignment.
• The last student to start is the first to complete the assignment.

Let's determine the starting order of the students:

1. If E-1 were the first to start, then he can't be the first to complete since it would violate the rule regarding the numbers and their positions. If he were to complete last, E-3 would start last, which contradicts E-3 completing first since E-1 is starting first. This causes inconsistency.
2. If E-2 were the first to start, we face a similar contradiction because E-2 can't also be the first to complete owing to the number and position mismatch, and similar constraints apply for his completion order.
3. Therefore, E-3 must be the one to start first. This leaves E-1 and E-2 to start later.

By elimination:

• E-3 starts first.
• Given E-3 starts first, they cannot finish last. That means E-1 and E-2 must finish later.
• Due to the constraint that the last to start finishes first, E-1 must start last and therefore finish first.

Conclusion: E-3 is the first student to start writing the assignment.

Answer 2

The problem requires determining which student finishes last based on provided constraints. Let's break down the information logically:

Students: E-1, E-2, E-3

Constraints: 

• Each student starts and completes at different times.
• The digit in their name doesn't match the order of starting or completing the assignment.
• The last student to start is the first to finish.

Logical Deduction:

• E-1 cannot start first or finish first, as his name's digit should not match the order.
• Similarly, E-2 cannot start second or finish second, and E-3 cannot start third or finish third.
• Considering the rule, the last to start finishes first. Hence, E-3 starts last and finishes first.
• E-1 and E-2 must start and complete in the remaining order. So, if E-2 starts first and finishes second, then E-1 must start second and finish last.

Conclusion: E-1 is the last to complete the assignment.
