"A six digit number 312132 has two 1's, two 2's and two 3's. This number has a very interesting attribute: 1 digit exists between two 1s, 2 digits exist between two 2's and 3 digits exist between two 3s. Can we add two more 4s to become an eight digit number and still holding the above attributes plus 4 digits exist between two 4s? "

  2. 12341234 or 23412341

  3. 41312432 or 23421314

  4. 34211234 or 23412341

Show answer
Correct Option: C
Explanation:

To solve this question, the user needs to understand the pattern of the given six-digit number and apply it to find the correct eight-digit number that satisfies all the given conditions.

The given six-digit number is 312132, which has two 1s, two 2s, and two 3s, with 1 digit between two 1s, 2 digits between two 2s, and 3 digits between two 3s.

We need to add two more 4s to the number and still keep the pattern. We know that four digits should exist between two 4s. Therefore, we can place the first 4 between the two 1s, and the second 4 between the two 2s, resulting in an eight-digit number.

Let's go through each option to find the one that satisfies all the given conditions:

A. 12341234 or 23421314: These options do not satisfy the condition that 4 digits should exist between two 4s.

B. 12341234 or 23412341: These options do not satisfy the condition that 3 digits should exist between two 3s.

C. 41312432 or 23421314: The option 23421314 satisfies all the given conditions, with two 1s, two 2s, two 3s, and two 4s, with 1 digit between two 1s, 2 digits between two 2s, 3 digits between two 3s, and 4 digits between two 4s.

D. 34211234 or 23412341: These options do not satisfy the condition that 2 digits should exist between two 2s.

Therefore, the correct answer is:

The Answer is: C. 41312432 or 23421314.

"I visited my math teacher last February. My teacher told me there were 3 groups of students came to his house on that day already. He also told me each group had different numbers of students. He said it was a coincidence that the product of the numbers of students in each group was equal to the visiting date (today’s date). He asked me if I knew how many people came in each group I looked at the calendar and found out that there might be 4 possible answers. So I asked my teacher a question. He replied: No. Then I gave him the correct answer. How many people came in each group? ‘Do you consider 1 person as a group?’ My teacher said: No. Do you know on what date I visited my teacher?"

Show answer
Correct Option: B
Explanation:

To solve this question, the user needs to understand the relationship between the number of students in each group, their product, and the visiting date. The user must also consider the possible visiting dates based on the given information.

Let's consider each option and eliminate those that are impossible based on the information provided:

Option A: 1, 2, and 3. The product of these numbers is 6. However, there are no dates in February that are the 6th of the month, so this option is not possible.

Option B: 2, 3, and 4. The product of these numbers is 24. February 4th is the only possible date in February that has a product of 24, so this option is possible.

Option C: 3, 4, and 5. The product of these numbers is 60. However, there are no dates in February that are the 60th of the month, so this option is not possible.

Option D: 4, 5, and 6. The product of these numbers is 120. However, there are no dates in February that are the 120th of the month, so this option is not possible.

Therefore, the only possible answer is:

The Answer is: B. 2, 3, and 4.

AI Explanation

To solve this question, we need to analyze the statements given by the suspects and determine who is telling the truth.

Let's go through each statement:

Robert: "One of the other two stole it. I did not do it." Scott: "One of the other two stole it. I did not do it." Tommy: "One of the other two stole it. I did not do it."

From their statements, we can conclude that each suspect is blaming the other two and claiming their own innocence. However, since the police later found out that Tommy was lying and there was only one thief, we can conclude that Tommy is the thief.

Therefore, the correct answer is C. Tommy.
