      Question

      If the price of a fruit basket is reduced by 35%, by what

      percentage should a family increase its consumption of fruits to ensure that their total expenditure on fruits remains unchanged?
      A 20.20% Correct Answer Incorrect Answer
      B 33.33% Correct Answer Incorrect Answer
      C 66.67% Correct Answer Incorrect Answer
      D 53.85% Correct Answer Incorrect Answer

      Solution

      ATQ;
      Let initial price of fruit basket be Rs. 100 per kg and initial consumption be 1 kg
      So, initial total expenditure = Rs. 100
      Reduced price of fruit basket = {100 – (35% of 100)} = Rs. 65
      So, new consumption = {100/65} = (20/13) kg
      Therefore, percentage increased = [{(20/13) – 1}/1] × 100 = 53.85%
