Ted’s score was in the 80th percentile out of 200 students in one class. In another class of 100 students there were 15 scores higher than ted’s. If nobody had Ted’s score, then Ted’s was what percentile of the two classes combined?  Choose the correct choice from the following.
A) 86  B) 84  C) 82  D) 80  E) 78
Being in 80% percentile out of 200 grades means Ted was 161st (from the least scores) in the class (as long as nobody had Ted’s grades), he outscored 160.   In another class his score would rank him 76 (from the least grade out of 101, 100+Ted), 75 had the grades higher than Ted.   So in combined classes he outscored 160+75=

235. There are 300 students 235/300=0.78   Answer: E (78%)   Generally being in x% means that x% has the grades less than you.   Ted in 80% --&gt; he outscored 80% of of 200=160 (Joseph is 161st).   Of the 100 scores from another class, 15 were higher than Ted 's, and the rest were lower --&gt; rest is 75, hence Ted outscored 75.   So out of total  200+100= 
<gadget id="calculator"> 200+100</gadget>
<output>300</output>
300, Ted outscored 160+75= 
<gadget id="calculator">160+75</gadget>
<output>235</output>
235. Hence he is in 235/300=78%.
