Answer 2

Calculating the Number of Mushrooms Lena Found

To calculate the number of mushrooms Lena found, we can use the information provided about Sasha finding 72 mushrooms and the relative amounts found by each person.

Let's denote the number of mushrooms found by Lena as L, by Sasha as S, and by Fedor as F.

According to the given information: - Fedor found mushrooms in 3 times more than Lena: F = 3L - Fedor found mushrooms in 2 times less than Sasha: F = 0.5S

We also know that Sasha found 72 mushrooms: S = 72

Using these relationships, we can calculate the number of mushrooms Lena found.

Calculation

We can start by finding the number of mushrooms Fedor found using the relationship between Fedor and Sasha: F = 0.5S Substitute the value of S: F = 0.5 * 72 F = 36

Now, we can use the relationship between Fedor and Lena to find the number of mushrooms Lena found: F = 3L Substitute the value of F: 36 = 3L L = 12

Conclusion

Therefore, Lena found 12 mushrooms.

This calculation is based on the provided information and the relationships between the number of mushrooms found by each person.
