      Question

      If the price of a cooking oil bottle is reduced by 30%,

      by what percentage should a family increase its consumption of cooking oil to ensure that their total expenditure on cooking oil remains unchanged?
      A 20.20% Correct Answer Incorrect Answer
      B 33.33% Correct Answer Incorrect Answer
      C 66.67% Correct Answer Incorrect Answer
      D 42.86% Correct Answer Incorrect Answer

      Solution

      ATQ;
      Let initial price of cooking oil be Rs. 100 per liter and initial consumption be 1 liter
      So, initial total expenditure = Rs. 100
      Reduced price of cooking oil = {100 – (30% of 100)} = Rs. 70
      So, new consumption = {100/70} = (10/7) liters
      Therefore, percentage increased = [{(10/7) – 1}/1] × 100 = 42.86%
