What is the area of the hall?I. Material cost of flooring per square m...
I. Material cost = Rs 2.50 per m2
II. Labour cost = Rs 3500
III. Total cost = Rs 14,500
Let the area be A sq. metres.
∴ Material cost = Rs (14500 – 3500)
= Rs 11,000
∴ 5A/2 = 11000
A = (11000 × 2)/5 = 4400 m2
Thus, all I, II and III are needed to get the answer.
∴ Correct answer is (c).
II. Labour cost = Rs 3500
III. Total cost = Rs 14,500
Let the area be A sq. metres.
∴ Material cost = Rs (14500 – 3500)
= Rs 11,000
∴ 5A/2 = 11000
A = (11000 × 2)/5 = 4400 m2
Thus, all I, II and III are needed to get the answer.
∴ Correct answer is (c).

What is the area of the hall?I. Material cost of flooring per square m...
Given information:
The problem gives us three statements:
I. The material cost of flooring per square meter is Rs 2.50.
II. The labor cost of flooring the hall is Rs 3500.
III. The total cost of flooring the hall is Rs 14,500.
To find:
We need to find the area of the hall.
Explanation:
Let's analyze each statement one by one:
Statement I:
The material cost of flooring per square meter is Rs 2.50.
This statement provides information about the cost of flooring material per square meter but doesn't give any information about the area of the hall. Therefore, this statement alone is not sufficient to find the area of the hall.
Statement II:
The labor cost of flooring the hall is Rs 3500.
This statement provides information about the cost of labor for flooring the hall but doesn't give any information about the area of the hall. Therefore, this statement alone is not sufficient to find the area of the hall.
Statement III:
The total cost of flooring the hall is Rs 14,500.
This statement provides information about the total cost of flooring the hall but doesn't give any information about the area of the hall. Therefore, this statement alone is not sufficient to find the area of the hall.
Combining the statements:
From statements I, II, and III, we can conclude that the total cost of flooring includes both the cost of materials and the cost of labor. However, without any information about the cost per square meter or the labor cost per square meter, we cannot determine the area of the hall.
Conclusion:
None of the statements alone provide sufficient information to find the area of the hall. Therefore, the correct answer is option C - All I, II, and III.
