A) 25%  B) 28%  C) 30%  D) 32.5%  E) 35%
1st year Income= I   1st year savings= S   1st year Expense= E1   2nd year Income = 1.35I   2nd year savings= 2S (100% increase)   2nd Year expense= E2   E1+ E2= 2E1   E2=E1   That means Expenses are same during both years. With increase of 35% income the savings increased by 100%.   or S= .35I   or S= 35% of Income   35% is the answer
