The image presents a "Can you Crack the Code?" challenge. It shows a lock icon with the text "Mathematics for Life" and the word "CODE" underneath.

There are 4 sets of 4-digit numbers. For each set, the challenge states whether the numbers are correct, wrong-placed, or right and well-placed.

9285: One number is correct but wrong placed.
1937: Two numbers are correct but wrong placed.
5201: One number is right and well placed.
6507: Nothing is correct.
8524: Two numbers are correct but wrong placed.

The challenge is to deduce the correct 4-digit code based on these clues about which digits are correct and whether they are in the right position or not. It's a logic puzzle that requires analyzing the clues to narrow down the possible solutions and identify the correct code.

can you solve it?

Sure, let's solve this step-by-step!

  1. From the clue for 5201, we know that one number is in the correct position. 5 and 1 cannot be correct as they appear in 6507, where no number is correct. So either 2 or 0 is the correct number.

  2. Looking at 8524, two numbers are correct but in the wrong place. 8 and 4 cannot be correct as they don't appear in any other sequence. So 5 and 2 must be the correct numbers, but in the wrong place.

  3. Now we know the code contains 2, 5, and either 0 or 1.

  4. In 9285, one number is correct but in the wrong place. It can't be 9 or 8 as they don't appear elsewhere. Between 2 and 5, one of them must be wrongly placed here.

  5. In 1937, two numbers are correct but in the wrong place. 1 can't be correct as it appears in 5201 where we determined only 2 or 0 could be correct. So 9, 3, and 7 must contain the other two correct numbers, which are 5 and either 0 or 1.

  6. The only way to satisfy steps 4 and 5 is if the code contains 0 (not 1), and the 5 is wrongly placed in 9285.

Therefore, the code must be 5027.

2 is correct and well-placed (5201 clue).
5 and 0 are correct but wrong-placed (9285 and 1937 clues).
7 is not in any of the other sequences, so it must be the remaining number.
