Math Question: What is the sum of the digits of the number 8402?

The sum of the digits in 8402 is found by adding 8 + 4 + 0 + 2, which equals 14.

Question: In how many ways can the number 8402 be rearranged such that the resulting number is divisible by 4?

To determine the divisibility by 4, the last two digits of a number must form a multiple of 4. The number 8402 can be rearranged in 4!/(2!1!1!) = (4x3)/(2x1) = 6 ways, but not all arrangements will be divisible by 4. Out of the six arrangements, only three choices are divisible by 4: 8402, 8204, and 4028. Therefore, there are three distinct ways to rearrange the digits of 8402 such that the resulting number is divisible by 4.

What is the sum of the digits in the number 8402?

To find the sum of the digits in 8402, we add each digit together. 8 + 4 + 0 + 2 = 14. Therefore, the sum of the digits in 8402 is 14.
