Math question: What is the sum of the digits in the number 1678?

To find the sum of the digits in 1678, we add each digit together. Starting from the left, we have 1 + 6 + 7 + 8 = 22. Therefore, the sum of the digits in 1678 is 22.

Math question: If a number is increased by 50% and then decreased by 20%, what is the final result when applied to the number 1678?

To find the final result, first increase 1678 by 50% which is (1678 * 0.5 = 839). The increased value is 1678 + 839 = 2517. Now, decrease this result by 20% (2517 * 0.2 = 503.4). Subtracting this reduction from the increased value gives the final result: 2517 - 503.4 = 2013.6. Therefore, when the number 1678 is increased by 50% and then decreased by 20%, the final result is approximately 2013.6.

Question: What is the sum of the digits in the number 1678, when each even digit is multiplied by 2 and each odd digit is multiplied by 3?

To find the sum, we multiply each digit by the corresponding factor, then add the results. The digit 1 remains unchanged (1 * 3 = 3), the digit 6 is multiplied by 2 (6 * 2 = 12), the digit 7 is multiplied by 3 (7 * 3 = 21), and the digit 8 is multiplied by 2 (8 * 2 = 16). Adding these results together, we have 3 + 12 + 21 + 16 = 52. Therefore, the sum of the digits in the number 1678, with the given multiplication scheme, is 52.
