      Question

      The length and breadth of a rectangular field are 50 m

      and 30 m respectively. If the length is increased by 20% and the breadth is decreased by 10%, then what will be the new area of the field?
      A 1620 sq m Correct Answer Incorrect Answer
      B 1335 sq m Correct Answer Incorrect Answer
      C 1520 sq m Correct Answer Incorrect Answer
      D 1275 sq m Correct Answer Incorrect Answer
      E None of these Correct Answer Incorrect Answer

      Solution

      Original length = 50 m Original breadth = 30 m New length = 50 + 20% of 50 = 50 + 10 = 60 m New breadth = 30 - 10% of 30 = 30 - 3 = 27 m New area = 60 x 27 = 1620 sq m Hence, the correct answer is 1620 sq m.
