---------------------
use R= I/PT it will be 55%

actually i 'think' the mistake you are doing is taking $99 as Interest....actually the interest is $99-$90=$9...now solve and you will get 5%

I=PRT/100
$9=($90*R*2)/100
$9*100=$180R
$900/180=R
therefore...R=5%

i think you should revise first and when you are confident that you know everything...do "atleast" 2 or 3 "recent" papers...on YOUR own...first do it and then check it with the mark scheme so that you know where do you make mistakes and Inshallah you will avoid them in the exam
