6 Alexander turned his attention towards India, since he had conquered Persia.

Which one of the statements below is logically valid and can be inferred from the above sentence?

 

  1. Alexander would not have turned his attention towards India had he not conquered Persia.

The head of newly formed government desires to appoint five of the six selected members P, Q, R, S, T and U to portfolios of Home, Power, Defense, Telecom, and Finance. U does not want any portfolio if S gets one of the five. R wants either Home or Finance or no portfolio. Q says that if S gets Power or Telecom, then she must get the other one. T insists on a portfolio if P gets one.

Which is the valid distribution of portfolios?

 

  1. P-Home, Q-Power, R-Defense, S-Telecom, T-Finance
  2. R-Home, S-Power, P-Defense, Q-Telecom, T-Finance
  3. P-Home, Q-Power, T-Defense, S-Telecom, U-Finance
  4. Q-Home, U-Power, T-Defense, R-Telecom, P-Finance

“U does not want any portfolio if S gets one of the five”

So, S and U cannot come together. Option C eliminated.

“R wants either Home or Finance or no portfolio”

So, options A and D eliminated.

So, answer is B. 

Just to confirm:

Q says that if S gets Power or Telecom, then she must get the other one

In B, S gets Power and Q gets Telecom

“T insists on a portfolio if P gets one”

In B, T is getting a portfolio.

Choose the most appropriate equation for the function drawn as thick line, in the plot below.

 

  1. x=y|y|x=y−|y|
  2. x=(y|y|)x=−(y−|y|)
  3. x=y+|y|x=y+|y|
  4. x=(y+|y|)

When y is -1, x is 2.

When y is positive x is 0.

So, x=(y|y|)

Most experts feel that in spite of possessing all the technical skills required to be a batsman of the highest order, he is unlikely to be so due to lack of requisite temperament. He was guilty of throwing away his wicket several time after working hard to lay a strong foundation. His critics pointed out that until he addressed his problem, success at the highest level will continue to elude him.

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

  1. He was already a successful batsman at the highest level.
  2. He was to improve his temperament in order to become a great batsman.
  3. He failed to make many of his good starts count.
  4. Improving his technical skills will guarantee success.

 

  1. iii and iv
  2. ii and iii
  3. i, ii and iii
  4. ii only

explanation:

“possessing all the technical skills” –  iv is false

“throwing away his wicket several time after working hard to lay a strong foundation” – iii is true

“he is unlikely to be so due to lack of requisite temperament” – ii is true

“success at the highest level will continue to elude him” – i is false

So, B.
