Question
What is the area of the hall? I: Total cost
(Labour + Material) of flooring the hall is Rs. 29,000 II: Labour cost of flooring the hall is Rs. 6,000. III: Material cost of flooring per sq. metre is Rs. 250. In each of the following questions, a question is followed by information given in three statements. You have to study the question along with the statements and decide that the information given in which of the statements is necessary to answer the question.Solution
Let the area of the hall be x m2. Then, total material cost = Rs. 250x Labour cost = Rs. 6000 Therefore, Total cost = 250x + 6,000 = 29,000 From this we get the value of x. Hence, all the three statements are required.
