Euro-I, Euro-II, Euro-III norms are related to

Show Hint

These staged standards fix fuel quality and vehicle emission limits, adopted in India as the Bharat Stage norms.

  • computer chips
  • auto fuel
  • none of these

The Correct Option is C

Solution and Explanation

This question is about what the Euro emission norms actually cover. Let's check each option.

  1. Automobile engine: Engines are designed to comply with these norms, but the norms themselves are defined in terms of fuel quality and tailpipe emission limits, not engine design.
  2. Computer chips: This has nothing to do with vehicles or fuel, so it is clearly wrong.
  3. Auto fuel: The Euro norms, adopted in India as the Auto Fuel Policy and Bharat Stage norms, set limits on pollutants like sulphur, benzene and lead in petrol and diesel, and on vehicle emissions. This is the closest and correct match.
  4. None of these: Since auto fuel is a valid and correct option, this does not apply.

So Euro-I, Euro-II and Euro-III are auto fuel and emission quality norms.

Let's summarize:

  • Euro norms in India are implemented through the Auto Fuel Policy and Bharat Stage standards.
  • They mainly target fuel quality and vehicle emission limits, not chip design.

The correct option is (3), auto fuel.

Read the scenario and answer the question:
The upper hinge of a dataset is the median of all the values to the right of the median of the dataset in an ascending arrangement, while the lower hinge of the dataset is the median of all the values to the left of the median of the dataset in the same arrangement.
For example, consider the dataset 4, 3, 2, 6, 4, 2, 7. When arranged in the ascending order, it becomes 2, 2, 3, 4, 4, 6, 7. The median is 4 (the bold value), and hence the upper hinge is the median of 4, 6, 7, i.e., 6. Similarly, the lower hinge is 2. 
A student has surveyed thirteen of her teachers, and recorded their work experience (in integer years). Two of the values recorded by the student got smudged, and she cannot recall those values. All she remembers is that those two values were unequal, so let us write them as A and B, where A < B. The remaining eleven values, as recorded, are: 5, 6, 7, 8, 12, 16, 19, 21, 21, 27, 29. Moreover, the student also remembers the following summary measures, calculated based on all the thirteen values: 
Minimum: 2
Lower Hinge: 6.5 
Median: 12 
Upper Hinge: 21 
Maximum: 29

Read the following scenario and answer the questions that follow.
A T20 cricket match consists of two teams playing twenty overs each, numbered 1 to 20. The runs scored in any over is a non-negative integer. The run rate at the end of any over is the average runs scored up to and including that over, i.e., the run rate at the end of the kth over is the average number of runs scored in overs numbered \(1, 2, …, k,\) where \(1 \leq k \leq 20, k\) a positive integer.
The following table indicates the run rate of a team at the end of some of the overs during a T20 cricket match (correct up to 2 decimal places), where \(1 \leq N – 2 < N + 6 \leq 20\), N a positive integer. It is also known that the team did not score less than 6 runs and more than 15 runs in any over.
