Answer 2

Calculating the Number of Fish Caught

Let's solve the problem step by step.

Step 1: Define the Variables - Let's assume the number of sazans caught is represented by S. - The number of perches caught is represented by P.

Step 2: Translate the Given Information into Equations - We are given that 2/5 of all the fish caught were sazans, which can be represented as: - S = (2/5)(S + P)

- We are also given that the number of perches is 7 more than the number of sazans, which can be represented as: - P = S + 7

Step 3: Solve the Equations - We can use the second equation to express P in terms of S: - P = S + 7

- Substitute the value of P from the second equation into the first equation: - S = (2/5)(S + S + 7)

- Solve for S: - S = (2/5)(2S + 7) - 5S = 4S + 14 - S = 14

Step 4: Calculate the Number of Perches - Using the value of S, we can calculate the number of perches: - P = S + 7 - P = 14 + 7 - P = 21

Answer:

The fishermen caught 14 sazans and 21 perches.
