Seven men can complete work in 52 days. How many days will 13 men finish the same work? - Seven
Seven dwarfs will cut 420 stumps in 15 hours. After five hours, the two dwarves disappear discreetly. How many hours will the remaining dwarves complete the task? - Sequences AP + GP
The three numbers that make up the arithmetic sequence have the sum of 30. If we subtract from the first 5, the second 4, and keep the third, we get the geometric series. Find AP and GP members. - Non-bank loan
Mrs. Smetanová took a non-bank loan. The monthly fee is calculated using a basic fee. The basic fee of 60 Kč is each month multiplied by the number of months for which Mrs. Smetanová knows the money borrowed (1st month = 1 × 60 Kč, 2nd month = 2 × 60 Kč, - Number sum difference
The sum of the two numbers is 18, and their difference is 10. What are the numbers? Calculate the arithmetic mean of the product and the proportion of these numbers. - The library
Anna stored a total of 126 books in three compartments of a library. The first compartment has 6 more books than the second. The number of books in the second compartment is the arithmetic mean of the number in the first and third compartments. Calculate - Bonuses
