Answer 1

Question: A,B,C and D are four-digit numbers in which 9 occurs only once and its place is:

• A: [9] [] [] []
• B: [] [9] [] []
• C: [] [] [9] []
• D: [] [] [] [9]

- Nothing is known about the rest of the digits.

What can you say about the numbers A, B, C and D?

Answer:

The correct answer is option 3. A is the greatest of all numbers.

Step-by-step explanation:

Given that the rest of the digits are smaller than 9, we conclude that:

The highest value that each of the numbers could be is:

• A = 9,888
• B = 8,999
• C = 8,898
• D = 8,889

Each number's highest value is lesser than the highest value of number A.

Therefore, A is the greatest of all numbers.
