Answer 3

Problem Analysis

We are given that a monkey, python, elephant, and parrot ate a total of 70 bananas. Each of them ate at least 1 banana. The monkey ate more bananas than anyone else, and the parrot and elephant together ate 45 bananas. We need to determine how many bananas the python ate.

Solution

Let's break down the information given: - Total number of bananas eaten = 70 - Each animal ate at least 1 banana - Monkey ate more bananas than anyone else - Parrot and elephant together ate 45 bananas

Let's assign variables to represent the number of bananas eaten by each animal: - Monkey = M - Python = P - Elephant = E - Parrot = Pa

From the given information, we can form the following equations: 1. M + P + E + Pa = 70 (Total number of bananas eaten) 2. M > P, M > E, M > Pa (Monkey ate more bananas than anyone else) 3. Pa + E = 45 (Parrot and elephant together ate 45 bananas)

We can solve this system of equations to find the number of bananas eaten by the python.

Solution Steps

1. Substitute equation 3 into equation 1 to eliminate Pa: M + P + E + (Pa + E) = 70 M + P + 2E = 70 - 45 M + P + 2E = 25

2. Substitute equation 2 into equation 1 to eliminate M: (M + P + E) + Pa = 70 (P + E) + Pa = 70 P + E + Pa = 70

3. Substitute equation 3 into equation 2 to eliminate Pa: M > P, M > E, M > Pa (P + E) > P, (P + E) > E, (P + E) > Pa P + E > P, P + E > E, P + E > 45 P + E > 45

4. Combine equations 2 and 3: P + E + Pa = 70 P + E > 45

5. Subtract equation 3 from equation 4 to eliminate Pa: (P + E + Pa) - (P + E) = 70 - 45 Pa = 25

Therefore, the parrot ate 25 bananas.

Answer

The python ate 25 bananas.
