The following question, there are three statements I, II and III. Read the question carefully and mark your answer according to which statements(s) is/are sufficient to the answer the question. Find the cost of the painting of the four walls of the room. Statement I: The perimeter of the floor of the room which is rectangular in shape is 56cm Statement II: The cost of painting one of the largest wall of the room is Rs. 850 Statement III: The area of the four walls of the room is 45 sq. more than the area of the roof of the room Correct Answer None of these
From statement I
⇒ 2(L + B) = 56
⇒ L + B = 28 ----(1)
From statement II
Let ‘C’ be the cost of painting
Cost of painting the larger wall = L × B × C = 850 ----(2)
From statement III,
⇒ 2(L + B)H - LB = 45 ----(3)
As all the three equations with 3 unknown quantities are obtained, answer cannot be determined.
∴ Option 5 is correct.
