 Question 6
Among 150 faculty members in an institute, 55 are connected with each other through Facebook ® and 85 are connected through WhatsApp ® . 30 faculty members do not have Facebook ® or WhatsApp ® accounts. The number of faculty members connected only through Facebook ® accounts is ______________.

Discuss it

Question 6 Explanation:
Suppose n(F) : number of faculty connected through facebook n(W) : number of faculty connected through whatsapp n(F ∪ W) : number of faculty connected through either facebook and whatsapp n(F ∩ W) : number of faculty connected through both facebook and whatsapp n(F ∪ W) = (total faculty - faculty not connected to anything) = (150-30) = 120 From number theory: n(F ∪ W) = n(F) + n(W) - n(F ∩ W) n(F) - n(F ∩ W) = n(F ∪ W) - n(W) n(F) - N(F ∩ W) = (120-85) = 35 n(F)- n(F ∩ W) is the faculty that has only facebook account, Hence answer is 35. This explanation has been contributed by Dharmesh Singh.
 Question 7
Computers were invented for performing only high-end useful computations. However, it is no understatement that they have taken over our world today. The internet, for example, is ubiquitous. Many believe that the internet itself is an unintended consequence of the original invention. With the advent of mobile computing on our phones, a whole new dimension is now enabled. One is left wondering if all these developments are good or, more importantly, required. Which of the statement(s) below is/are logically valid and can be inferred from the above paragraph? (i) The author believes that computers are not good for us. (ii) Mobile computers and the internet are both intended inventions
 A (i) only B (ii) only C both (i) and (ii) D neither (i) nor (ii)

Question 7 Explanation:
ubiquitous - everywhere unintended - unplanned
```--> Author has not said anything against internet and mobile computing
but is talking about the surprising usage of these.

"Many believe that the internet itself is an unintended consequence of
the original invention."
--> The author says that many believe that 'internet itself' is unplanned
but actually both internet and mobile computers are unplanned(unintended)
inventions.

Question 8 Explanation:
Given statement doesn't say that - "All hill-stations have a lake" but any place having a lake is surely a hill station. ---> Ooty may or may not be a hill station Hence (i) is false ---> Here, it is not a compulsion that a place need to have exactly one lake to be a hill station. Hence (ii) is also false This explanation has been contributed by Mohit Gupta.
 Question 9
In a 2 × 4 rectangle grid shown below, each cell is a rectangle. How many rectangles can be observed in the grid?
 A 21 B 27 C 30 D 36
General Aptitude    GATE-CS-2016 (Set 2)
Discuss it

Question 9 Explanation:
To form a rectangle, we must choose two horizontal sides and two vertical sides. So, number of rectangles we can form is mC2 * nC2. Since there are three horizontal lines, we can choose the horizontal sides in 3C2 ways. Since there are five vertical lines, we can choose the vertical sides in 5C2 ways. The number of rectangles we can form is = 5C2 * 3C2 = {(5*4)/2}*{(3*2)/2} = 10*3 = 30 So, option (C) is correct.
 Question 10
Choose the correct expression for f(x) given in the graph.
 A A B B C C D D
GATE-CS-2016 (Set 2)
Discuss it

Question 10 Explanation:
Simply, there are two test cases: ---> In graph, at x = 1, f(x) = 2 Let's find the values at x = 1 in given options: A) f(1) = 1 - |1-1| = 1 - 0 = 1 B) f(1) = 1 + |1-1| = 1 + 0 = 1 C) f(1) = 2 - |1-1| = 2 - 0 = 2 D) f(1) = 2 + |1-1| = 2 + 0 = 2 Hence (A) and (B) are incorrect. Now, ---> In the graph, at x=0, f(x) = 1 Let's find the values at x = 1 in the remaining options, i.e. C and D. (c) f(0) = 2 - |0-1| = 2 - 1 = 1 (d) f(0) = 2 + |0-1| = 2 + 1 = 3 Hence, C is the correct answer. This explanation is contributed by Mohit Gupta.
