Quizplus · Accepted Answer

The problem is a multiplication and subtraction problem combined. The bottom part of the problem shows the result of multiplying the top number (which is 8 followed by a missing digit) by the second number (which is a single digit followed by 1), and then subtracting that product from 2604. The product of the multiplication is 2520, and when subtracted from 2604, it gives 84 as the remainder. To find the missing digits, we can work backwards from the multiplication product (2520) and the remainder (84). The only combination of digits that fits this pattern, considering the multiplication and subtraction involved, is 43, making the correct answer 4, 3. This means the multiplication involved is 81 × 31, which equals 2520, and 2604 - 2520 equals 84.
