Problem 1: Children collecting different types of grains

The problem states that children collected a total of 10 kg of oak, pine, and individual grains. It also provides the information that 60% of the total collected grains are oak nuts, and 25% are pine nuts. We need to determine the weight of linden grains collected.

To solve this problem, we can follow these steps:

1. Calculate the weight of oak nuts: 60% of 10 kg = 6 kg. 2. Calculate the weight of pine nuts: 25% of 10 kg = 2.5 kg. 3. Calculate the weight of the remaining grains: 100% - (60% + 25%) = 15% of 10 kg = 1.5 kg. 4. Since linden grains are the remaining grains, the weight of linden grains collected is 1.5 kg.

Therefore, the weight of linden grains collected is 1.5 kg.
