Question 889012
We have 3 test score (60+70+80) and we have taken 5 total test. We know the average of our test scores is 80. How do we find out the other 2 test scores?**
***
let x=average of other 2 test scores
{{{(60+70+80+2x)/5=80}}}
210+2x=5*80=400
2x=190
x=95
average of other 2 test scores=95
