Direction : Study the following table chart carefully and answer the questions given beside.

The following table represents Maximum marks of five subjects and marks obtained by five students in five subjects.

 Students Physics (Out of 75) Mathematics (Out of 100) Chemistry (Out of 75) Biology (Out of 75) English (Out of 120) Ragini 56 65 45 38 95 Rohan 60 52 62 55 88 Sohan 50 78 70 58 88 Mohini 55 82 65 66 110 Mohan 42 96 64 72 104
Important for :
1
Marks obtained by Ragini in Chemistry and Biology together is what percent of the marks obtained by Mohini in Physics and Mathematics together?
» Explain it
B
Marks obtained by Ragini in Chemistry and Biology together = 45 + 38 = 83

Marks obtained by Mohini in Physics and Mathematics together = 55 + 82 = 137

 Reqd. % = 83 = 60.58% 137

Hence, option B is correct.
2
Find the respective ratio of the marks obtained by all the students in Mathematics and marks obtained by all the students in Chemistry.
» Explain it
B
Marks obtained by all the students in Mathematics = 65 + 52 + 78 + 82 + 96 = 373

Marks obtained by all the students in Chemistry = 45 + 62 + 70 + 65 + 64 = 306

Required ratio = 373 : 306

Hence, option B is correct.

3
Find the overall percentage of Sohan in all the subjects.
» Explain it
C
Total marks in all the subjects = 75 + 100 + 75 + 75 + 120 = 445

Marks obtained by Sohan in all the subjects = 50 + 78 + 70 + 58 + 88 = 344

 Reqd. % = 344 = 77.3% 445

Hence, option C is correct.
4
Find the difference between percentage of marks obtained by Mohan in English and that of Rohan in Physics.
» Explain it
A
Percentage of marks obtained by Mohan in English

 = 104 × 100 = 86.67% 120

Percentage of marks obtained by Rohan in Physics
 = 60 × 100 = 80% 75

Required difference = 86.67 – 80 = 6.67%

Hence, option A is correct.

5
Find the sum of marks obtained by Rohan in all the subjects.
» Explain it
D
Sum of marks obtained by Rohan in all the subjects = 60 + 52 + 62 + 55 + 88 = 317

Hence, option D is correct.

In this article we will discuss What is Data Interpretation, How its important for UGC NET Paper 1 Exam.

What is Data Interpretation and how its useful for UGC NET Paper 1.

In our day-to-day life, data is reported in the newspapers, on television, and in magazines. The data involves business, government, sports and many other topics. It is represented in an organized fashion, making it easy to interpret what you hear and read in the media. Those set of problems is being asked in different kind of form like Pie Chart di, Bar Chart di, Table Chart di, line chart di and info chart etc.

Now come back to the point data interpretation,  Data has to be well organized for it to be useful. This process of interpreting and analysing data to extract meaningful information from it is Data Interpretation. Solving Data Interpretation problems involves the use of basic formulas and manipulation of numbers.

Data Interpretation is calculation-intensive. It consists of a myriad of graphs, charts and tables form which you have to glean and analyse data. The key to cracking this area is to quickly identify the key pieces of data that you require to work on the questions asked.

Problems in Data interpretation are probably the closest in resemblance to the kind of problems you will be dealing with as a manager. They test your decision-making ability and speed using the minimum possible data. They help you to draw conclusions from collected data, support decision making, and contribute to better process, product, and quality models.

Data Sufficiency problems involve testing your quantitative concepts. They usually take the form of a logical puzzle. Instead of solving a data sufficiency problem, all you need to do is determine if the given information is enough to solve the problem. To solve Data Interpretation Questions & Answers for Teaching Exams like UGC NET Paper 1, UPTET, CTET, NET, SLET, SET, CSIR UGC NET, PRT, TGT, PGT you need to brush up your calculation skills; you need to perform calculations faster and accurately than others. The difficult Data interpretations should be solved within 10-12 minutes. The DI of moderate level should not consume more than 7-9 minutes of the time and easy DI's should be finished within 3.5-4 minutes.

In these Data Interpretation Quizzes, you familiarized yourself with the key concepts and improved your problem-solving abilities. At Smartkeeda you will get Easy level data interpretation to High level data interpretation at low cost. Practice and tests are important to optimize your preparation. First take the quizzes regarding your exams and take full mock test at Testzone to improve your problem-solving skills. Questions that have appeared in the previous UGC NET Paper 1 exams are also a part of these quizzes. Go through them you can understand where the focus lies in an examination environment. The detailed solutions of the questions may provide some alternate strategies that can help you improve your speed and accuracy.
