company b looses #1,575 for every employee who quits before 90 days. What is the total amount the company will loose if 2 employees quit before 30 days 1 employee quits on day 41 and 1 employee quits on day 100

To solve this riddle, let's list down the prime numbers between 30 and 80:

31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79

Next, let's analyze the given clues. The riddle states that the tens digit is one more than the ones digit.

Looking at the list, we can eliminate numbers that don't fit this clue. For example, 31 and 79 have a difference of two between the tens and ones digit.

So, we are left with the following numbers that have a difference of one between the tens and ones digit:

37, 41, 43, 47, 53, 59, 61, 67, 71

Now, we just need to determine which of these remaining numbers is a two-digit whole number between 30 and 80.

The only number that meets all the criteria is:

41

Therefore, the answer to the riddle is 41.

To solve this riddle, we need to find a 2-digit prime number between 30 and 80, where the tens digit is one more than the ones digit.

Let's break down the problem step by step:

Step 1: Identify the 2-digit prime numbers between 30 and 80.
Prime numbers are numbers that are only divisible by 1 and themselves. Between 30 and 80, the prime numbers are: 31, 37, 41, 43, 47, 53, 59, 61, 67, and 71.

Step 2: Check which of these numbers have the tens digit one more than the ones digit.
To identify the numbers, we can separate them into tens and ones digits:
- 31: ones digit = 1, tens digit = 3
- 37: ones digit = 7, tens digit = 3 (not fulfilling the condition)
- 41: ones digit = 1, tens digit = 4
- 43: ones digit = 3, tens digit = 4 (not fulfilling the condition)
- 47: ones digit = 7, tens digit = 4 (not fulfilling the condition)
- 53: ones digit = 3, tens digit = 5
- 59: ones digit = 9, tens digit = 5 (not fulfilling the condition)
- 61: ones digit = 1, tens digit = 6
- 67: ones digit = 7, tens digit = 6 (not fulfilling the condition)
- 71: ones digit = 1, tens digit = 7

From this analysis, we can see that the number that fulfills all the given conditions is 41.

Therefore, the answer to the riddle is 41.
