      C Quantity-I ≤ Quantity-II Correct Answer Incorrect Answer
      D Quantity-I = Quantity-II or No relation Correct Answer Incorrect Answer
      E Quantity-I ≥ Quantity-II Correct Answer Incorrect Answer

      Solution

      ATQ, Quantity I: Let monthly income of ‘Amit’ originally be Rs.‘100a’ Monthly expenditure of ‘Amit’ originally = 0.45 × 100a = Rs. 45a Monthly savings of ‘Amit’ originally = 0.55 × 100a = Rs. 55a Increased monthly income of ‘Amit’ = 1.176 × 100x = Rs. 117.6a Increased monthly expenditure of ‘Amit’ = 117.6a – 45a = Rs. 72.6a Desired % = [(72.6a – 55a)/55a] = 32% So, Quantity I = 32% And, Quantity II = 36% So, Quantity-I < Quantity-II
