What is the area of the hall?
I.
Material cost of flooring per square metre is Rs. 2.50
II.
Labour cost of flooring the hall is Rs. 3500
III.
Total cost of flooring the hall is Rs. 14,500.
Answer : Option C
Explanation :
I. Material cost = Rs. 2.50 per m^{2}
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.
\(\frac {5 A} { 2 } \)=11000 A =\([ \frac { 11000 *2} {5 } ]\)=4400 m^{2}.
Thus, all I, II and III are needed to get the answer.
Correct answer is (C).
