Math Question: If 7 is subtracted from 3 times a number, and the result is divided by 2, the outcome is 1564. What is the number?

Let the number be x. According to the given information, we form the equation (3x - 7) / 2 = 1564. To find x, we multiply both sides by 2 to eliminate the fraction: 3x - 7 = 1564 * 2. Simplifying, we have 3x - 7 = 3128. Then, we add 7 to both sides: 3x = 3128 + 7. Hence, 3x = 3135. Finally, we divide both sides by 3 to isolate x: x = 3135 / 3 = 1045. The number is 1045.

Math Question: The number 1564 is multiplied by 3, squared, divided by 2, subtracted by 250, and then divided by 7. What is the result?

To find the result, we first multiply 1564 by 3 to get 4692. Then, we square 4692 to obtain 21,996,864. Dividing this by 2 gives us 10,998,432. Subtracting 250 from this yields 10,998,182. Lastly, dividing 10,998,182 by 7 gives us the final result of 1,571,168.2857142857142857142857142857 (approximately). Thus, the result is approximately 1,571,168.29.

Question: If a number is increased by 25% and then decreased by 15%, what is the resulting value of the number 1564?

To find the resulting value, we first increase 1564 by 25%. 25% of 1564 is 391, so the increased value is 1564 + 391 = 1955. Then, we need to decrease this value by 15%. 15% of 1955 is 293.25. Subtracting this from 1955 gives a resulting value of 1955 - 293.25 = 1661.75. Therefore, the resulting value of the number 1564, after being increased by 25% and then decreased by 15%, is 1661.75.
