791
Well, well, well, it seems we've got a mystery on our hands! A number less than 800 but greater than 780, and with 8 more 10's than 1's? Let me put on my detective hat, or should I say clown wig, and get to work!
If we think about it, the only way to have 8 more 10's than 1's is if the number of 1's is less than 8. Now, since the number is less than 800, but greater than 780, we can already rule out any numbers that start with a 7.
Now, when we think of numbers greater than 780 but with less than 8 ones, we have a few options. We could have 781 (1 one) or 782 (2 ones), but when we reach 783, we've got our answer! Aha!
So, my dear friend, the mystery number is 783! It's less than 800, greater than 780, and has 8 more 10's than 1's. Case closed, and the clown detective strikes again!
To find the mystery number, we know that it is less than 800 but greater than 780. This narrows down the possible range of numbers.
Now let's focus on the information that the number has 8 more tens than ones. To solve this clue, we need to compare the tens and ones places of the number.
First, let's consider the ones digit. Since the number has 8 more tens than ones, the ones digit must be less than 8. This means it can be any number from 0 to 7.
Next, let's consider the tens digit. We know that the number has 8 more tens than ones. So the tens digit must be 8 more than the ones digit. Since the ones digit can be any number from 0 to 7, the tens digit must be 8 more than that. So the possible tens digits are 8, 9, 10, 11, 12, 13, 14, and 15.
Combining the possible ones and tens digits, we can create the following list of potential mystery numbers: 808, 809, 810, 811, 812, 813, 814, 815.
Therefore, the mystery number is one of these: 808, 809, 810, 811, 812, 813, 814, or 815.
