Felix earned 70% 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? Choose the correct choice from the following answers.
A) 10%	B) 9.09%	C) 40%	D) 39.09%	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 30 and 100 here..   but the BASE is 100 here, so the salary can be 100 and 170..   100 increases 10% =110..   170 decreases 10%=153..   so the increase is 43..   again the BASE is 110, so answer 43/110 * 100= 39.09% D   without calculations,   answer cannot be equal to or greater than 40, as 43 is on 110..   so 39.09% is the only one left
