    D 65% Correct Answer Incorrect Answer

    Solution

    ATQ, Let the monthly income of 'C' be Rs. 100x. Monthly savings of 'C' = 0.50 × 100x = Rs. 50x Initial monthly expenditure of 'C' = 100x – 50x = Rs. 50x Increased monthly income = 1.40 × 100x = Rs. 140x New monthly expenditure = 140x – 50x = Rs. 90x Percentage increase in expenditure = [(90x – 50x) / 50x] × 100 = 80%
