Math Question: Find the sum of the digits of the number 1914 multiplied by the quotient of 200 divided by 9, then subtract the product of the square root of 1914 and 5, rounded to the nearest whole number.

To solve the given question, first find the sum of the digits in 1914: 1 + 9 + 1 + 4 = 15. Then, calculate the quotient of 200 divided by 9: 200 ÷ 9 = 22.22222... (repeating). Multiplying this quotient by the sum of the digits gives: 15 × 22.22222... = 333.333333... (repeating). Now, calculate the square root of 1914 ≈ 43.7320604, and multiply it by 5 to get ≈ 218.660302. Rounding this to the nearest whole number gives 219. Finally, subtract the rounded product from the previous multiplication: 333.333333... - 219 = 114.333333... (repeating).

Math question: What is the sum of all the positive three-digit whole numbers starting from 1914 up to 9999?

To find the sum, we need to calculate the arithmetic series using the formula Sn = (n/2) * (a + l), where Sn is the sum, n is the number of terms, a is the first term, and l is the last term. The first term is 1914, and the last term is 9999. The number of terms can be calculated by subtracting the first term from the last term and adding 1. Thus, the number of terms is (9999 - 1914) + 1 = 8086. Substituting these values into the formula, the sum is Sn = (8086/2) * (1914 + 9999) = 4,093,200. Therefore, the sum of all positive three-digit whole numbers from 1914 to 9999 is 4,093,200.

Math question: What is the sum of all positive multiples of 19 less than or equal to 1914?

To find the multiples, divide the highest number (1914) by the common difference (19) to get 100.5. Since we can have only whole numbers, the highest multiple of 19 less than or equal to 1914 is 19 * 100 = 1900. The total number of terms is the floor value of 100.5, which is 100. Therefore, the sum is calculated using the formula for the sum of an arithmetic series: S = n/2 * (first term + last term), where n is the number of terms. In this case, S = 100/2 * (19 + 1900) = 50 * (1919) = 95,950. The sum of all positive multiples of 19 up to 1914 is 95,950.
