For what value of n, the sum of digits in the number (10^n + 1) is 2?
A
For n = 0 only
B
For any whole number n
C
For any positive integer n only
D
For any real number n
Correct Answer: Option B
Explanation
To find for what value of n the sum of digits of (10^n + 1) is 2, we can just test the values described in the options.
First, let's look at the pattern for positive integers (n = 1, 2, 3...):
- If n=1: 10^1 + 1 = 11. Sum of digits =
