Felix earned 30% 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) 7%	D) 6.36%	E) It cannot be determined from the information given.
the very first step requires taking some numbers for each..   ONE should be 100...   it is easy to take 70 and 100 here..   but the BASE is 100 here, so the salary can be 100 and 130..   100 increases 10% =110..   130 decreases 10%=117..   so the increase is 7..   again the BASE is 110, so answer 7/110 * 100= 6.36% D   without calculations,   answer cannot be equal to or greater than 7, as 7 is on 110..   so 6.36% is the only one left   ANSWER:6.36%
