Felix earned 80% more per month than Oscar. If Felix’s salary is decreased 10% and Oscar’s salary is increased by 10%, then Felix would be earning what percent more than Oscar?
Select the correct option
A) 10%  B) 9.09%  C) 48%  D) 47.27%  E) It cannot be determined from the information given.
This Q is all about taking the correct BASE for taking %s..   the very first step requires taking some numbers for each..   ONE should be 100...   it is easy to take 20 and 100 here..   but the BASE is 100 here, so the salary can be 100 and 180..   100 increases 10% =110..   180 decreases 10%=162..   so the increase is 52..   again the BASE is 110, so answer 52/110 * 100= 47.27% D   without calculations,   answer cannot be equal to or greater than 48, as 52 is on 110..   so 47.27% is the only one left
