Data Sufficiency

Unwarranted Assumptions

With data sufficiency problems, be careful not to read any more into a statement than what is given. The main purpose of some difficult problems is to lure you into making an unwarranted assumption.If you avoid the temptation, these problems can become routine.

Example: Did Incumbent I get over 50% of the vote?

(1) Challenger C got 49% of the vote.

(2) Incumbent I got 25,000 of the 100,000 votes cast.

Solution:

If you did not make any unwarranted assumptions, you probably did not find this to be a hard problem. What makes a problem difficult is not necessarily its underlying complexity; rather a problem is classified as difficult if many people miss it. A problem may be simple yet contain a psychological trap that causes people to answer it incorrectly. The above problem is difficult because many people subconsciously assume that there are only two candidates. They then figure that since the challenger received 49% of the vote the incumbent received 51% of the vote. This would be a valid deduction if C were the only challenger. But we cannot assume that. There may be two or more challengers. Hence, (1) is insufficient.

Now, consider (2) alone. Since Incumbent I received 25,000 of the 100,000 votes cast, I necessarily received 25% of the vote. Hence, the answer to the question is ‘No, the incumbent did not receive over 50% of the vote.’ Therefore, (2) is sufficient to answer the question. The answer is B.

GATE Overview

What is GATE :

The Graduate Aptitude Test in Engineering (GATE) is an all-India examination administered and conducted in eight zones across the country by the GATE Committee comprising faculty from Indian Institute of Science, Bangalore and seven Indian Institutes of Technology on behalf of the National Coordinating Board - GATE, Department of Education, Ministry of Human Resources Development (MHRD), Government of India.


Objective:

To identify meritorious and motivated candidates for admission to Post Graduate Programmes in Engineering, Technology, Architecture and Pharmacy at the National level. To serve as benchmark for normalisation of the Undergraduate Engineering Education in the country.

Why should we take GATE:

  1. M.Tech degree leads to specialization and furthering of interest in a certain area which may lead to Ph.D .
  2. M.Tech degree is best for those wishing to apply for Faculty/Research positions in educational Institutes/R&D centers.

Important Dates:

  1. Availability of GATE forms: October, 1st week
  2. Last Date for filling up forms: November, 1st week
  3. Exam Date: 2nd Sunday of February
  4. Results: March 3rd week

Examination Details:

  1. The examination is a single paper of 3 hours duration and generally consists of Section A (Objective Type) which is of 75 marks and Section B (Problem Type) which is of 75 marks. Total: 150 marks.
  2. You have to opt for your subject and study as per the syllabus mentioned in the GATE brochure.
  3. The subjects of our interest are Computer Science and Engineering, Electronics & Communication Engineering., Electrical Engineering and Instrumentation Engineering. Other subjects are also available such as Mathematics, Physics, etc.
  4. Results of qualified candidates in GATE will give All India Rank and indicate percentile score. For example, a percentile score of 99 means you are in the top 1% category of the candidates who appeared for GATE.
  5. Candidates who get less than 70 percentile get no score card.
  6. GATE scores are valid for 2 years. You may reappear the GATE exam if you are not satisfied with the earlier score and the new score (if better than the old one) will be used for admission purposes.

Note: Validity of GATE 2009 Score will be for a period of ONE YEAR  ONLY from the date of announcement of results.


After the Exam, what next:

  1. After publication of GATE results, students must apply to individual Institutes to get their application forms.
  2. Institutes advertise M.Tech admissions in leading newspapers from 1st April till end July. However some Institutes do not advertise and therefore students have to get the forms themselves.
  3. In the application forms, you have to mention your GATE score alongwith other details.
  4. The concerned Institute may conduct written test and/or interview for the purpose of admission.
  5. General thumb rules: If your GATE score in Computer Science is 96 percentile or more then you can try for IITs, if between 85 - 96 percentile, then apply for top RECs, JADAVPUR, SHIBPUR, ROORKEE, etc. If less than 85, you have to look for appropriate institutes.

Scholarship:

During the pursuit of M.Tech, you are paid a scholarship of Rs. 5000.00 per month by the Government of India. This amount is enough for living expenses including purchase of books, etc. The scholarship is paid for the entire 18 months M.Tech period.


SPECIAL:

It is always better for  3rd year students to also appear GATE alongwith Final Year students since:

  1. GATE score is valid for 1 years.
  2. The syllabus as required by GATE is generally over by 5th semester.
  3. Anyway, it will be a good try ! If it is a bad score you can always try again.
