Product of two numbers is 6845. If the first number is 5 times the second…

Solution:

1. Let the two numbers be 5x and x.

2. Their product is 5x · x = 5x² = 6845, so x² = 6845/5 = 1369.

3. Take the square root: x = 37 (positive value).

4. Sum = 5x + x = 6x = 6 × 37 = 222.

Therefore, the sum of the numbers is 222.

Shortcut: x = sqrt(Product/5), then sum = 6x.
