Math question: If I add 532 to a certain number, subtract 326 from the result, and then multiply by 12, the final answer is 95,244. What is the original number?

Let's call the original number x. According to the question, we have the equation: ((x + 532) - 326) × 12 = 95,244. First, we simplify the equation: (x + 532 - 326) × 12 = 95,244. Next, combine like terms: (x + 206) × 12 = 95,244. Now, divide both sides by 12 to isolate x: x + 206 = 7,937. Lastly, subtract 206 from both sides: x = 7,937 - 206 = 7,731. Therefore, the original number is 7,731.

Math question: What is the sum of the digits of the number 7958?

To find the sum of the digits of 7958, we add the individual digits. The digit 7 plus the digit 9 equals 16. Then, we add the digit 5 to get 21. Finally, we add the digit 8 to get a result of 29. Therefore, the sum of the digits in 7958 is 29.

Math question: What is the sum of the digits of the number 7958 multiplied by the quotient of its hundreds digit divided by the tens digit?

To solve, we first find the sum of the digits of 7958: 7 + 9 + 5 + 8 = 29. Next, we calculate the quotient of its hundreds digit (9) divided by the tens digit (5), which is 1.8. Finally, we multiply the sum of the digits (29) by this quotient (1.8) to get 52.2. Therefore, the answer is 52.2.
