      LPG cylinders from a local seller who charges Rs. 50 per cylinder. The seller has a subsidy scheme by which if you return the empty cylinder purchased from him, you will get a refund of Rs. 20 per cylinder. You cannot borrow money from anyone.

      A 131 Correct Answer Incorrect Answer
      B 132 Correct Answer Incorrect Answer
      C 133 Correct Answer Incorrect Answer
      D 134 Correct Answer Incorrect Answer

      Solution

      1st cylinder = Rs.50, and after that we can have each cylinder of Rs. 30 (We can return the old one). That is 50 + 30x <= 4000 X<=131.67 X= 131 Since X is for remaining cylinders, but we also bought 1st cylinder, hence total cylinders = 132.
