<h3>
<u>Answer:</u></h3>
Average of salary of Anne and David is 1.25 of Peter's Salary
<h3>
<u>Explanation:</u></h3>
In the question, relations between salaries of Peter, Anne, and David is given. From the given relations, we need to make few equations and calculate the average of Anne and David in terms of Peter's Salary.
Let us assume Peter's Salary as P.
Then we can calculate Anne's salary A =
.
Also David's salary = D = ![2 \times P](https://tex.z-dn.net/?f=2%20%5Ctimes%20P)
Average of Anne's and David's salary = ![\frac{A+D}{2}](https://tex.z-dn.net/?f=%5Cfrac%7BA%2BD%7D%7B2%7D)
Average of Anne's and David's salary = ![\frac{\frac{P}{2} + 2 \times P}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Cfrac%7BP%7D%7B2%7D%20%2B%202%20%5Ctimes%20P%7D%7B2%7D)
Average of Anne's and David's salary = ![\frac{5 \times P}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B5%20%5Ctimes%20P%7D%7B4%7D)
Average = 1.25 \times P
