Due to the large potato harvest this year, the farm bought a new, more powerful sorter in addition to the old one. Now both machines work simultaneously, and therefore the daily harvest is processed in 12 hours. If only the old machine were working, it wo - Marble color distribution
I have 100 marbles. One-quarter of them are white, and 3 fifths of the rest are blue. 1 third of those that are neither blue nor white are red, and the rest are green. How many marbles do I have? - Third unknown number
The number A is 5 more than the number C and 10 less than the number B. The sum of A+B=100. What is the C number? - Number percentage reduction
If we reduce the unknown number by 24%, we get the number 358. Determine the unknown number. - Isosceles triangle angles
Determine the size of the interior angles in an isosceles triangle if you know that the angle opposite the base is 15° greater than the angles at the base. - Father son age
