Discuss it


Question 1 Explanation: 
Here, part IV is incorrect. "was losing consciousness" shows continuous process of losing consciousness, but he was not in the process, rather he just lost consciousness. So, the correction is " was losing consciousness "  → " lost consciousness ".
 
Thus, IV is the correct choice.

Discuss it


Question 4 Explanation: 
Given series is 2,5,10,17,26,37,50,64.

Here total number of terms are 8..i.e. A(1) to A(8).

For the 1st 7 terms, you can observe the relationship 
between the terms which is 
A(n) = [ A(n-1) - {A(n-1) + A(n-2)} + 2 ] where n >= 3

Now for the 8th term i.e. A(8), this relationship violates.
According to the relationship,
A(8) = [A(7) + {A(7) - A(6)} + 2 ]
= [50 + {50 - 37} + 2 ]
= 50 + 13 + 2
= 65.
But in the series it is 64. Hence 64 doesn't belong to 
the series. 
Question 5
The table below has question-wise data on the performance of students in an examination. The marks for each question are also listed. There is no negative or partial marking in the examination. GATECS2014Q5 What is the average of the marks obtained by the class in the examination
A
1.34
B
1.74
C
3.02
D
3.91
General Aptitude    GATE-CS-2014-(Set-3)    
Discuss it


Question 5 Explanation: 
As you can see from each row that the total number of
students in the class are 44.

Now we have to find the total number of marks obtained
by the class.

Marks are given for correct answers only. 
No negative or partial marking.

For 1st question total marks obtained are : 2*21 = 42
For 2nd question total marks obtained are : 3*15 = 45
For 3rd question total marks obtained are : 2*23 = 46

hence total marks obtained by the class are = 42+45+46 = 133

Now, Average marks obtained = Total Marks/Total no of students
= 133/44
= 3.02
Hence C is the answer.
Question 6
A dance programme is scheduled for 10.00 a.m. Some students are participating in the programme and they need to come an hour earlier than the start of the event. These students should be accompanied by a parent. Other students and parents should come in time for the programme. The instruction you think that is appropriate for this is
A
Students should come at 9.00 a.m. and parents should come at 10.00 a.m.
B
Participating students should come at 9.00 a.m. accompanied by a parent, and other parents and students should come by 10.00 a.m.
C
Students who are not participating should come by 10.00 a.m. and they should not bring their parents. Participating students should come at 9.00 a.m.
D
Participating students should come before 9.00 a.m. Parents who accompany them should come at 9.00 a.m. All others should come at 10.00 a.m.

Question 6 Explanation: 
  • A is not the appropriate instruction as only the participating students and their parents have to come at 9.00 a.m. and other students along with their parents have to come at 10.00 a.m., while the statement in A says that all students should come at 9.00 a.m. and all the parents should come at 10.00 a.m.
  • B is the appropriate instruction and covers all the aspects of the information to be conveyed.
  • C is not the appropriate instruction as the non participating students have to come at 10.00 a.m. with their parents, while the statement in B says that these students have to come without their parents.
  • D is not the appropriate instruction as it states that the participating students have to come before 9.00 a.m. whereas they have to come at 9.00 a.m.
So B is Correct option.
Question 7
By the beginning of the 20th century, several hypotheses were being proposed, suggesting a paradigm shift in our understanding of the universe. However, the clinching evidence was provided by experimental measurements of the position of a star which was directly behind our sun. Which of the following inference(s) may be drawn from the above passage?
(i) Our understanding of the universe changes
    based on the positions of stars
(ii) Paradigm shifts usually occur at the
     beginning of centuries
(iii) Stars are important objects in the
      universe
(iv) Experimental evidence was important in
     confirming this paradigm shift 
A
(i), (ii) and (iv)
B
(iii) only
C
(i) and (iv)
D
(iv) only

Question 7 Explanation: 
Paradigm shift means a fundamental change in approach to something or change in the underlying assumptions in relation to something. This change, as per the question, was verified with the experimental measurements of the position of a star that was behind the sun. (i) is incorrect as it generalizes the experimental evidence of the star and assumes it to be always true, which may not be the case every time. (ii) is also incorrect. If there was a paradigm shift at the beginning of the 20th century, it does not necessarily means that all paradigm shifts usually occur at the beginning of centuries. (iii) is incorrect as it again generalizes an experimental statement. Stars proved to be important in the given case does not necessarily imply that they would be important every time. (iv) is correct as it is clearly understood from the given case conditions that this experimental measurements provided a clinching (solid/concrete) evidence to our understanding of the universe.   So, D is the correct choice as only (iv) is the correct statement.   Please comment below if you find anything wrong in the above post.
Question 8
The Gross Domestic Product (GDP) in Rupees grew at 7% during 2012-2013. For international comparison, the GDP is compared in US Dollars (USD) after conversion based on the market exchange rate. During the period 2012-2013 the exchange rate for the USD increased from Rs. 50/ USD to Rs. 60/ USD. India’s GDP in USD during the period 2012-2013
A
increased by 5 %
B
decreased by 13%
C
decreased by 20%
D
decreased by 11%

Discuss it


Question 8 Explanation: 
Suppose original GDP was x then its international
value is x/50. 

Now GDP becomes 107*x/100 and its international 
value becomes (107x/100)/60= 107x/6000.

The value has decreased by (x/50)-(107x/6000).  
Percentage approx 10.8% = 11%
Question 9
The ratio of male to female students in a college for five years is plotted in the following line graph. If the number of female students in 2011 and 2012 is equal, what is the ratio of male students in 2012 to male students in 2011? GATECS2014Q9
A
1:1
B

Question 9 Explanation: 
Number of female students in 2011 and 2012 are equal.
Suppose they are x.

Now,
Males students in 2011 = Female students in 2011 
                       = x (as the ratio is 1)

And in 2012, Male students / Female students = 
                                       1.5(Given)

Hence Male students in 2012 = 1.5 * Female students 
                            = 1.5 * x

Now ratio of Male students in 2012 to Male students
in 2011 = ( 1.5 * x ) / x
        = 1.5 / 1
i.e. 1.5 : 1

Hence C is the answer. 
Question 10
Consider the equation: (7526)8 − (Y)8 = (4364)8 , where (X)N stands for X to the base N. Find Y.

Discuss it


Question 10 Explanation: 
(X)N stands for X to the base N. 7526(8) - Y(8) = 4364(Y) Base 8(Octal) uses digits 0 to 7. Now Y(8) = 7526(8) - 4364(8) The subtraction of octal numbers follows the same rules as the subtraction of numbers in any other number system. The only variation is in borrowed number. In the decimal system, you borrow a group of 10(10). In the binary system, you borrow a group of 2(10). In the octal system you borrow a group of 8(10).
