Percentages

[kbarnes660]

I am trying to figure out how to figure out test scores based on a weighted test. We can either weight 2 parts of a test on a 70/30 or 60/40 scale. If I get a 80% on the greater and a 90% on the lesser how do I figure out what the total percentage out of 100 would be? In another words, how do I figure out how to figure out the percentage of a percentage? Thanks

Just trying to figure out test scores at my Fire Department. It is an old was that our former Chief used to grade scores for testing. He is not around anymore and we are trying to figure it out. It appears that the people taking the test have chosen the 60/40 scale. Just trying to figure out how to calculate each individual score so.

If the first part is weighted "60" and the second "40" and you got 80% on the first part, 90% on the second, then your overall score was .6(.80)+ .4(.90)= .48+ .36= .84 or 84%. If the first part was instead weighted "70" and the second "30", then your overall score was .7(.80)+ .3(.90)= .56+ .27= .83 or 83%.
