Find two numbers whose sum is 6 and whose difference is 4.

  1. 2 and 4

  2. 3 and 5

  3. 4 and 6

  4. 5 and 7

The correct answer is: 3 and 5

Explanation Since the sum of the two numbers is 6 and their difference is 4, the two numbers must be 4 and 6, as shown in option C. The other options are incorrect because either their sum is not 6 or their difference is not 4. For example, option A has a sum of 6, but the difference is only 2. Option D has a difference of 2, but the sum is not 6. Only option B meets both criteria of having a sum of 6 and a difference of 4, making it the correct answer.
