The monthly income of Manisha was ₹1,20,000 and her monthly expenditure was ₹55,000. Next year, her income increased by 22% and her expenditure increase by 10%. Find the percentage increase in her savings (correct to 2 decimal place).

32.15%

22% = \(\frac{11}{50}\)  & 10% = \(\frac{1}{10}\)

Saving = 120000 -  55000 = 65000

New Income = 120000 + \(\frac{11}{50}\) × 120000  = 146400

New Expenditure = 55000 + \(\frac{1}{10}\) × 55000 = 60500

New saving = 146400 - 60500 = 85900

Percentage Increase in saving = \(\frac{85900-65000}{65000}\) × 100

= 32.1538%

= 32.15%  (approx)
