Problem Analysis

We are given that a duck eats a certain amount of food in 5 days, and a chicken eats the same amount of food in 20 days. We need to determine how many days it will take for a duck and a chicken together to eat 2000 grams of food.

Solution

Let's assume that the amount of food eaten by the duck in 5 days is represented by D grams, and the amount of food eaten by the chicken in 20 days is represented by C grams.

We can set up the following equation based on the given information:

D/5 + C/20 = 2000

To solve for the number of days it will take for the duck and chicken together to eat 2000 grams of food, we need to find the value of D + C.

To do this, we can rearrange the equation as follows:

**D + C =
