Question: If 2 is subtracted from a four-digit number, the result is 7210. What is the number?

To determine the unknown number, let's add 2 to 7210. This will give us the original four-digit number. Thus, 7210 + 2 = 7212. Hence, the original number is 7212.

Question: If the number 7210 is multiplied by 3 and then divided by 5, how many whole numbers less than or equal to the result can be formed by rearranging its digits?

To find the number of whole numbers that can be formed by rearranging the digits of 7210 multiplied by 3 and divided by 5, let's calculate the result. Multiplying 7210 by 3 gives us 21630. Dividing 21630 by 5 yields 4326. To rearrange the digits of 4326, we can consider the different possibilities. Starting with the leftmost digit, the digit 4 cannot be moved to form any other number. The digit 3 can be moved to three different positions, creating 3426, 4236, and 4263. The digit 2 can also be moved to three different positions, resulting in 3426, 2436, and 2463. Finally, the digit 6 can be moved to two different positions, giving us 3426 and 2436. So, in total, there are seven whole numbers (3426, 4236, 4263, 2436, 2346, 2463, and 4326) that can be formed by rearranging the digits of 7210 multiplied by 3 and divided by 5.

Question: If the number 7210 is multiplied by 3, then divided by 2, what is the result?

To solve this, we multiply 7210 by 3 which gives us 21630. Then, we divide 21630 by 2 to get 10815. Therefore, when the number 7210 is multiplied by 3 and divided by 2, the result is 10815.
