Answer 2

Solution:

To solve this problem, we can follow these steps:

1. Calculate the number of mushrooms collected by Lena. 2. Calculate the number of mushrooms collected by Masha. 3. Determine the number of mushrooms collected by Katya.

Let's proceed with the calculations.

1. Calculate the number of mushrooms collected by Lena: - Lena collected 2/9 of all the mushrooms.

2. Calculate the number of mushrooms collected by Masha: - Masha collected 25/49 of the remaining mushrooms after Lena's collection.

3. Determine the number of mushrooms collected by Katya: - To find out how many mushrooms Katya collected, we can subtract the total number of mushrooms collected by Lena and Masha from the total number of mushrooms collected by all three.

Now, let's calculate the number of mushrooms collected by each person.

Calculation:

1. Lena collected 2/9 of all the mushrooms. - Total mushrooms collected by Lena = (2/9) * 126 - Total mushrooms collected by Lena = 28

2. Masha collected 25/49 of the remaining mushrooms after Lena's collection. - Remaining mushrooms after Lena's collection = 126 - 28 = 98 - Total mushrooms collected by Masha = (25/49) * 98 - Total mushrooms collected by Masha = 50

3. Determine the number of mushrooms collected by Katya: - Total mushrooms collected by Katya = Total mushrooms - (Mushrooms collected by Lena + Mushrooms collected by Masha) - Total mushrooms collected by Katya = 126 - (28 + 50) - Total mushrooms collected by Katya = 48

Answer:

Katya collected 48 mushrooms.
