Previous percent increase is 33.3% so From 2004-2005; 162*33.3 = 5394.6 then divide it by 100 we get 53.946; adding this with 162 + 53.946 = 215.9460, this is the actual per-student profit whereas we take it as 216.
Now, my question is in the main/real GRE xm do I need to put the 215.94 or just by leveling 215.94 to 216 and then put 216 as an answer. ???
Be careful, an increase from 60 to 80 is a 1/3 increase.
1/3 = 33.3333333.....%
In your solution, you rounded 33.3333333.....% down to 33.3%
So, your final answer is a bit off.
If we stick with the fraction increase of 1/3, we need only find 1/3 of 162, which is exactly 54
So, our final answer = 162 + 54 = 216
