JEE - Cost of Flooring a Rectangular Hall
Question: What is the cost of flooring a rectangular hall?
I. The length of the rectangle is 6 m and breadth is two third of its length.
II. Perimeter of rectangle is 200 m.
III. The cost of flooring the area of 100 cm2 is Rs.45.
To find: Cost of flooring the rectangular hall.
Statement I: The length of the rectangle is 6 m and breadth is two third of its length.
Statement II: Perimeter of rectangle is 200 m.
Statement III: The cost of flooring the area of 100 cm2 is Rs.45.
Solution:
- To find the cost of flooring the rectangular hall, we need to know the area of the hall.
- From Statement I, we can find the breadth of the hall. Let's assume the length of the hall is L, then breadth will be (2/3)L. So, area of the hall will be L*(2/3)L = (2/3)L^2.
- From Statement II, we can find the perimeter of the hall. Let's assume the length of the hall is L and breadth is (2/3)L, then perimeter will be 2(L + (2/3)L) = (8/3)L. So, (8/3)L = 200 or L = 75.
- Now we know the length and breadth of the hall, so we can find the area of the hall which will be (2/3)L^2 = (2/3)*75*75 = 3750 sq.m.
- From Statement III, we know the cost of flooring an area of 100 sq.cm. So, we need to convert 3750 sq.m to sq.cm. 1 sq.m = 10,000 sq.cm. So, 3750 sq.m = 3750*10,000 sq.cm = 37,50,000 sq.cm.
- The cost of flooring 100 sq.cm is Rs.45. So, the cost of flooring 37,50,000 sq.cm will be (37,50,000/100)*45 = Rs.16,87,500.
Conclusion:
- Statement I gives us the breadth of the hall, which is required to find the area of the hall.
- Statement II gives us the perimeter of the hall, which is required to find the length of the hall.
- Statement III gives us the cost of flooring an area of 100 sq.cm, which is required to find the cost of flooring the entire hall.
- Therefore, all three statements are required to answer the question. So, the answer is option 'c' - Only II.

To find: Cost of flooring the rectangular hall.
Statement I: The length of the rectangle is 6 m and breadth is two third of its length.
Statement II: Perimeter of rectangle is 200 m.
Statement III: The cost of flooring the area of 100 cm2 is Rs.45.
Solution:

- From Statement I, we can find the breadth of the hall. Let's assume the length of the hall is L, then breadth will be (2/3)L. So, area of the hall will be L*(2/3)L = (2/3)L^2.
- From Statement II, we can find the perimeter of the hall. Let's assume the length of the hall is L and breadth is (2/3)L, then perimeter will be 2(L + (2/3)L) = (8/3)L. So, (8/3)L = 200 or L = 75.
- Now we know the length and breadth of the hall, so we can find the area of the hall which will be (2/3)L^2 = (2/3)*75*75 = 3750 sq.m.
- From Statement III, we know the cost of flooring an area of 100 sq.cm. So, we need to convert 3750 sq.m to sq.cm. 1 sq.m = 10,000 sq.cm. So, 3750 sq.m = 3750*10,000 sq.cm = 37,50,000 sq.cm.
- The cost of flooring 100 sq.cm is Rs.45. So, the cost of flooring 37,50,000 sq.cm will be (37,50,000/100)*45 = Rs.16,87,500.
Conclusion:
- Statement I gives us the breadth of the hall, which is required to find the area of the hall.
- Statement II gives us the perimeter of the hall, which is required to find the length of the hall.
- Statement III gives us the cost of flooring an area of 100 sq.cm, which is required to find the cost of flooring the entire hall.
- Therefore, all three statements are required to answer the question. So, the answer is option 'c' - Only II.
