2∙𝐿
𝐶𝐴
, we
obtain the inequality
2∙𝐿
𝐶𝐴
≤ 1 +
𝐿𝑇𝐴

. Based on the last inequality and the right side of the double inequality
obtained in point 2, it is possible to write down the system of inequalities of the following form.

Adding the two inequalities included in this system of inequalities together, we form the
following inequality:
2 ∙
𝐿
𝐶𝐴
≤ 2. Transferring the number 2 to the right side of the inequality, we get similar
(analogous) resulting inequalities of the form
0,5 ≤
𝐿
𝐶𝐴
≤ 1 or 1 ≤
𝐶𝐴
𝐿
≤ 2.
It can be seen from these similar inequalities that the minimum and maximum normative values of
the indicator
𝐿
𝐶𝐴
is [0,5; 1] within the interval and the minimum and maximum normative values of the
indicator
𝐶𝐴
𝐿
is [1; 2] should be in the interval.

By multiplying the inequalities in this system, we get the resulting double
0,1 ≤

𝐿
≤ 2 inequality.
It can be seen from this inequality that the minimum and maximum standard values of the indicator
𝐿𝑇𝐴

are [0,1; 2] within the interval and the minimum and maximum normative values of the indicator
𝐿
𝐿𝑇𝐴
is [0,5; 10] should be within the interval.
