1.  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.
2.  A. I and II only B. II and III only C. All I, II and III D. Any two of the three E. None of these

Explanation :

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.

$$\frac {5 A} { 2 }$$=11000 A =$$[ \frac { 11000 *2} {5 } ]$$=4400 m2.

Thus, all I, II and III are needed to get the answer.
