Answer:
<em>Grades to be scored in 3rd exam = 88</em>
Step-by-step explanation:
Given that average of 3 numbers is 85.
First two numbers are 81 and 86.
To find:
3rd number so that average is 85
Solution:
Let the third number = ![x](https://tex.z-dn.net/?f=x)
Formula for average is:
![Average = \dfrac{Sum\ of\ numbers}{Total\ count\ of\ numbers}](https://tex.z-dn.net/?f=Average%20%3D%20%5Cdfrac%7BSum%5C%20of%5C%20numbers%7D%7BTotal%5C%20count%5C%20of%5C%20numbers%7D)
Here, sum of numbers = ![81+86+x =167+x](https://tex.z-dn.net/?f=81%2B86%2Bx%20%3D167%2Bx)
Total count of numbers = 3
![85 = \dfrac{167+x}{3}\\\Rightarrow x=255-167\\\Rightarrow \bold{x=88}](https://tex.z-dn.net/?f=85%20%3D%20%5Cdfrac%7B167%2Bx%7D%7B3%7D%5C%5C%5CRightarrow%20x%3D255-167%5C%5C%5CRightarrow%20%5Cbold%7Bx%3D88%7D)
