Math question: If the number 1859 is increased by twice the sum of its digits, what is the final result?

To find the answer, we first sum the digits of 1859, which are 1 + 8 + 5 + 9 = 23. Now, doubling this sum gives us 2 * 23 = 46. Therefore, when we increase 1859 by twice the sum of its digits, we get 1859 + 46 = 1905. Hence, the final result is 1905.

Math Question: If a number is divided by 5 and then increased by 75, the result is 742. What is the original number?

Let's represent the original number as x. According to the given information, we have the equation (x/5) + 75 = 742. To solve this equation, we subtract 75 from both sides: x/5 = 742 - 75 = 667. Next, we multiply both sides by 5 to isolate x: x = 667 × 5 = 3335. Therefore, the original number is 3335.

Math question: What is the smallest prime number greater than 1859 but less than 2000?

To find the prime number, we start by eliminating even numbers greater than 1859. Next, we check numbers greater than 1859 to see if they are divisible by any smaller prime numbers. After a few checks, we find that the smallest prime number greater than 1859 but less than 2000 is 1861. A prime number is a number greater than 1 that has no divisors other than 1 and itself. 1861 satisfies this condition as it is only divisible by 1 and 1861 itself.
