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 ______________.
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.

(i) The author believes that computers are not good for us. (ii) Mobile computers and the internet are both intended inventions
both (i) and (ii)
neither (i) nor (ii)

Question 9 Explanation:
5C2 * 3C2
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.
