Multiple choice

Directions: Each question is followed by three statements. You have to study the question and all the three statements given and decide whether any information provided in the statement(s) is redundant and can be dispensed with while answering the questions. What is the area of the rectangle? A. Perimeter of the rectangle is 80 m. B. The total cost of flooring the rectangle at Rs. 2 per square metre is Rs. 750. C. Breadth of the rectangle is 15 m.

  1. Only B

  2. A and B together

  3. Either B alone or A and C together

  4. None

  5. A and C together
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Area = L * B. A (Perimeter) gives 2(L+B) = 80, so L+B = 40. B (Cost) gives Area * 2 = 750, so Area = 375. C gives B = 15. To find Area, we need L and B. B alone gives the area directly. A and C together give L+15=40, so L=25, and Area=25*15=375. Thus, either B alone or A and C together are sufficient.

AI explanation

Statement B gives the total flooring cost as Rs. 750 at Rs. 2 per square meter, so dividing the cost by the rate directly gives the area as 375 square meters, making B sufficient alone. Statement A gives the perimeter as 80 meters and statement C gives the breadth as 15 meters, allowing the length to be found as 25 meters and the area to be calculated as 375 square meters. Therefore, either statement B alone or statements A and C together are required.
