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 ______________.

  1. 35
  2. 45
  3. 65
  4. 90

Answer: A

Explanation:

Given,
Total faculty member = 150
The faculty member not connected to anything = 30
n(FB) : number of faculty member connected through Facebook = 55
n(WhatsApp) : number of faculty member connected through WhatsApp = 85

n(FB ∪ WhatsApp) = number of faculties connected through either Facebook and WhatsApp
= (Total faculty member - The faculty member not connected to anything)
= (150-30) = 120

n(FB ∩ WhatsApp): number of faculties connected through both Facebook and WhatsApp

Now, from number theory:
n(FB ∪ WhatsApp) = n(FB) + n(WhatsApp) - n(FB ∩ WhatsApp)
n(FB ∩ WhatsApp) = n(FB) + n(WhatsApp) - n(FB ∪ WhatsApp)
= 55 + 85 - 120 <=> 20
So, the faculty that has only Facebook account = n(FB) - n(FB ∩ WhatsApp)
= (55 - 20) <=> 35

Hence option (A) is the right answer.


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.

(i) The author believes that computers are not good for us.
(ii) Mobile computers and the internet are both intended inventions

  1. (i) only
  2. (ii) only
  3. both (i) and (ii)
  4. neither (i) nor (ii)

Answer: D

Explanation:

In the above passage, the author has not tried to say anything against the internet and mobile computing. He is only talking about the surprising way of computers are being used today. So, (i) statement does not follow.

According to this line "Many believe that the internet itself is an unintended consequence of the original invention." Thus (ii) statement does not follow.

Therefore option (D) will be the right answer.

Which of the statement(s) below is/are logically valid and can be inferred from the above sentences?

  1. (i) only
  2. (ii) only
  3. both (i) and (ii)
  4. neither (i) nor (ii)

Answer: D

Explanation:

Ooty is not a hill station. So, statement (i) is false.
