Question: If the sum of two numbers is 30 and one of the numbers is a multiple of 5, which of the following could be the other number?

Options:

Correct Answer: 20

Solution:

If one number is 20 (a multiple of 5), the other number would be 10, making it a valid option.

If the sum of two numbers is 30 and one of the numbers is a multiple of 5, which of the following could be the other number?

If the sum of two numbers is 30 and one of the numbers is a multiple of 5, which of the following could be the other number?

Step 1: Understand that we have two numbers that add up to 30.
Step 2: Identify that one of these numbers is a multiple of 5.
Step 3: List the multiples of 5 that are less than or equal to 30: 0, 5, 10, 15, 20, 25, 30.
Step 4: For each multiple of 5, subtract it from 30 to find the other number.
Step 5: Check if the result (the other number) is a valid option.
Step 6: For example, if we take 20 (a multiple of 5), then the other number is 30 - 20 = 10.
Step 7: Since 10 is a valid number, it could be the other number.
