Answer 1

100-60=40(%)- лиственных
60-40=20 (%) -приходится на 25 деревьев

Answer 2

Problem Analysis

To solve this problem, we need to determine the total number of trees planted in the park. We are given that 60% of the trees are coniferous (хвойные) and that the number of coniferous trees is 25 more than the number of deciduous (лиственные) trees.

Solution

Let's assume the total number of trees planted in the park is represented by the variable T. We can set up the following equations based on the given information:

1. The number of coniferous trees is 60% of the total number of trees: 0.6T. 2. The number of coniferous trees is 25 more than the number of deciduous trees: 0.6T = 0.4T + 25.

To solve this equation, we can subtract 0.4T from both sides:

0.6T - 0.4T = 25

Simplifying the equation gives us:

0.2T = 25

Now, we can solve for T by dividing both sides of the equation by 0.2:

T = 25 / 0.2

Calculating this gives us:

T = 125

Therefore, the total number of trees planted in the park is 125.

Answer

The total number of trees planted in the park is 125.
