Question

The successor of a 3 digit number can be a _____ digit or a _____ digit number.

• A. 3, 4
• B. 2, 3
• C. 2, 4
• D. 4, 5

Answer 1

The correct option is A 3, 4

The set of 3 digit number is from 100 to 999.

From 100 to 998, the successor of any 3 digit number is a 3 digit number only.

But for 999, the successor is 1000 which is a 4 digit number.

So, the successor of a 3 digit number can be a 3 digit or a 4 digit number.
