      the following year, her income went up by 13% and her expenditure increased by 6%. What is the percentage rise in her savings?
      A 25.55% Correct Answer Incorrect Answer
      B 17.33% Correct Answer Incorrect Answer
      C 62.45% Correct Answer Incorrect Answer
      D 31.38% Correct Answer Incorrect Answer

      Solution

      ATQ,

      Initial savings = 29000 – 21000 = Rs. 8000

      New income = 1.13 × 29000 = Rs. 32770

      New expenses = 1.06 × 21000 = Rs. 22260

      New savings = 32770 – 22260 = Rs. 10510

      Percentage increase = [(10510 – 8000)/8000] × 100 = 31.38%
