This blog post of mine focuses on the three types of questions asked in GATE – it tries to give an in-depth analysis of the type of questions you actually face in GATE. If you want to have an over-all idea on the pattern of GATE exam, please visit my earlier blog article titled: GATE 2013 Exam Structure/Pattern/Format
All the questions asked in GATE are multiple choice objective type questions. These objective questions can be classified into following three types:
1.0 Individual questions: Each question either 1 mark or 2 marks.
2.0 Common Data Questions: Each question 2 marks.
3.0 Linked answer questions: Each question 2 marks.
While you should not bother to learn too much about the Individual type questions (as you must have already come across them), you should take care to learn what are Common Data & Linked answer type questions.
These are usual MCQ (Multiple Choice Questions), each question is independent of other. For example – following was a question from GATE CE -2010 paper:
Q: Two coins are simultaneously tossed. The probability of two heads simultaneously appearing is
(A) 1/8 (B) 1/6 (C) 1/4 (D) 1/2
Common Data Questions:
In these types of questions, one problem statement/passage is given, which is followed by two questions. Both of these questions are independent of each other and hence the answer of one question is not required to find the answer of the other question.
Example: You can find below two Common Data question (Q50 & Q51) from actual GATE CE -2010 paper:
Statement: The moisture holding capacity of the soil in a 100 hectare farm is 18cm/m. the field is to be irrigated when 50 percent of the available moisture in the root zone is depleted. The irrigation water is to be supplied by a pump working for 10hours a day, and water application efficiency is 75%. Details of crops planned for cultivation are as follows:
Q50. The capacity of irrigation system required to irrigate crop X in 36 hectares is
(A) 83litres/sec (B) 67 liters/sec (C) 57 liters/sec (D) 53 liters/sec.
Q51. The area of crop Y that can be irrigated when the available capacity of irrigation
system is 40 liters / sec is
(A) 40hectares (B) 36 hectares (C) 30 hectares (D) 27 hectares
Linked answer questions:
These questions are very similar to Common Data Questions. One problem statement/passage is given, which is followed by two questions. But unlike Common Data Questions, in Linked answer questions, answer of one question is required to find the answer of the other question.
Example: You can find below two Linked answer questions (Q52 & Q53) from actual GATE CE -2010 paper:
Statement: A doubly reinforced rectangular concrete beam has a width of 300mm and an effective depth of 500mm. the beam is reinforced with 2200mm2 of steel in tension and 628mm2 of steel in compression. The effective cover for compression steel is 50mm. Assume that both tension and compression steel yield. The grades of concrete and steel used are M20 and Fe250 respectively. The stress lock parameters (rounded off to first two decimal places) for concrete shall be as per IS 456:200.
Q52. The depth of neutral axis is
(A) 205.30mm (B) 184.56mm (C) 160.91mm (D) 145.30mm
Q53. The moment of resistance of the section is
(A) 206.00kN-m (B) 209.20 kN-m (C) 236.80 kN-m (D) 251.90kN-m,
I am giving blow two simple graphics to show you the difference between Common Data Questions & Linked answer Questions:
Hope with above information of GATE Question type/Question Pattern you have got the required insight on the type of questions you are actually going to face in GATE. From time to time I would keep posting more prep materials for GATE. So keep visiting me.
