If in each number, both first and third digits are added and after that second digit is subtracted from that addition then how many numbers are less than 2 after mentioned operation?

The correct option is Two.

Let's analyze the problem step-by-step.
We need to apply a specific operation to each number and check how many of the resulting values are less than 2.

Step 1: Understand the operation
For a given three-digit number with digits (First, Second, Third):
1. Add the first digit and the third digit: (First + Third).
2. Subtract the second digit from this sum: (First + Third) - Second.

Step 2: Apply the logical condition
We are looking for cases where:

$(\text{First}+\text{Third})-\text{Second}<2$

Step 3: Evaluate the options
After performing this operation for all numbers in the given set, exactly Two numbers yield a result that is strictly less than 2.

Therefore, the correct answer option is Two.
