      20% on rent and 10% on electricity bills. If he spent 20% of the remaining on entertainment and saved the rest which is Rs. 960, then find his total income.
      A Rs. 2,400 Correct Answer Incorrect Answer
      B Rs. 3,000 Correct Answer Incorrect Answer
      C Rs. 3,600 Correct Answer Incorrect Answer
      D Rs. 4,000 Correct Answer Incorrect Answer
      E None of these Correct Answer Incorrect Answer

      Solution

      Let total income of Amit be Rs. '100x' So, amount left after he spent part of it on groceries, rent and electricity bills = 100x - (0.30 + 0.20 + 0.10) X 100x = Rs. '40x' So, 0.80 X 40x = 960 Or, x = (960/32) = 30 So, total income of Amit = 100x = 100 X 30 = Rs. 3,000 Hence, option b.
