Consider the following 3 link relative values: 87.1, 129.6, and 111.4. The average link relative (to 1 decimal place) is equal to:

a. 101.2
b. 98.7
c. 107.9
d. 6.9

Answer :

To find the average of the given link relative values, we follow these steps:

  1. Add the Link Relative Values:

    • Add up the three link relative values provided:
      [tex]87.1 + 129.6 + 111.4 = 328.1[/tex]

  2. Count the Number of Values:

    • There are 3 link relative values.

  3. Calculate the Average:

    • Divide the sum by the number of values:
      [tex]\text{Average} = \frac{328.1}{3}[/tex]
    • Performing the division gives:
      [tex]\text{Average} \approx 109.3667[/tex]

  4. Round to 1 Decimal Place:

    • Round 109.3667 to one decimal place. The first digit after the decimal is 3, and the digit after 3 is 6, so we round up.
      [tex]\text{Average} \approx 109.4[/tex]

Thus, the average link relative, rounded to one decimal place, is approximately 109.4.

Unfortunately, this value doesn't match any given options (101.2, 98.7, 107.9, 6.9), indicating a potential error or miscalculation in the context of the question. However, based on the standard mathematical method, 109.4 is the accurate answer.
