Question

The difference between two numbers is 2. When each number is rounded to nearest hundred, the difference between them is 100. What could the numbers be?

Answer 1

• The difference between two numbers is 2:

`101 - 99 = 2`

• each number is rounded to nearest hundred

101 → 200

99 → 100

• the difference between them is 100:

`200 - 100 = 100`

⇒ the numbers could be: 99 and 101

other pairs of numbers: (199,201), (299,301) ...
