let the income of person be Rs y So his expenditure be 75% of income which is = 0.75y Saving = y- 0.75y = 0.25y Now after increment of 20 % in income the new income becomes = 1.2y Given that bew expenditure is 10% more than previous one.So , new expenditure is = 1.1 × 0.75y = 0.825y New savings = 1.2y - 0.825y = 0.375y Percentage increase in savings =$$frac {0.375y-0.25y}{0.25y}$$×100 = 50%
