DILR DPP 2 - Road Construction Stats – Top 10 Firms (NH, SH, OR)

Directions for questions 1 to 4: The instructions given below is followed by a set of four questions. Choose the most appropriate answer to each question.


The Ministry of Road Transport and Highways was analyzing the length (in km) of roads constructed per day by ten road construction companies in the last financial year. Roads were classified into three categories National Highways (NH), State Highways (SH) and Other Roads (OR) as shown in the bar graph below. These nine belong to the top ten companies in terms of total length (in km) of roads construction per day. The remaining company (in the top ten) is J, which constructed National Highways of 29 km per day.


The table below shows the ranks of the above ten companies among all road construction companies in India in
terms of total length (in km) of roads constructed per day in each of the three categories of roads.

The company(ies) constructing the largest length of road in a particular category is ranked 1 in that category, the company(ies) constructing second largest length of road is ranked 2 and so on. In case two or more companies construct equal lengths of roads in the same category, all those companies get an equal rank in that category.

For example, let us say that in a particular category there are only 4 companies; companies X and Y constructed equal lengths of roads and companies P and Q constructed roads of length larger than that of both X and Y, then
Case 1: If P = Q > X = Y, then Both P and Q will be ranked 1 and both X and Y will be ranked 2.
Case 2: If P > Q > X = Y, then P will be ranked 1, Q will be ranked 2, and both X and Y will be ranked 3.
Missing ranks in the table are denoted by ‘–’.
