Direction: Each of the questions below consists of a question and three statements numbered I, II and III given below it. You have to study the questions and decide the data in which of the statements are sufficient to answer the questions.
-
What is the cost of flooring a rectangular hall?
I. Perimeter of the hall is 76 m
II. Area of the hall is 336 m2.
III. Cost of flooring per square metre is $550.
-
- I and III only
- II and III only
- Any two of the three
- All I, II and III
- None of these
Correct Option: B
From above given statement , we can see that
I. Perimeter of the rectangular hall = 2 ( length + breadth ) = 76 m
⇒ 2 ( L + B ) = 76
∴ L+ B = 38
II. Area of the hall = 336 m2
⇒ length x breadth = 336 m2
III. Cost of flooring per square metre = $550.
Combining (II) and (III),
Total cost = Area of the hall x Cost of flooring per square metre
= 336 × 550 = $184800.
