      20% is spent on essentials. After essentials, he uses 20% of the balance on food. He spends one-fourth of the remaining amount on transport. Following these expenses, he spends 25% of what's left on entertainment. He saves the remaining sum, which amounts to Rs. 45,000. Calculate his total income.
      A Rs. 1,20,000 Correct Answer Incorrect Answer
      B Rs. 1,25,000 Correct Answer Incorrect Answer
      C Rs. 1,30,000 Correct Answer Incorrect Answer
      D Rs. 1,40,000 Correct Answer Incorrect Answer
      E None of these Correct Answer Incorrect Answer

      Solution

      Let the income of Vikram be Rs. '100q'.
      Money spent on essentials = 0.20 Γ— 100q = Rs. '20q'
      Remaining income = 100q – 20q = Rs. '80q' Money spent on food = 0.20 Γ— 80q = Rs. '16q'
      Remaining income = 80q – 16q = Rs. '64q' Money spent on transport = (1/4) Γ— 64q = Rs. '16q'
      Remaining income = 64q – 16q = Rs. '48q' Money spent on entertainment = 0.25 Γ— 48q = Rs. '12q'
      Savings = 48q – 12q = Rs. '36q' So, 36q = 45,000
      Or, q = 1,250
      Therefore, income of Vikram = 1,250 Γ— 100 = Rs. 1,25,000
