This Week's Punches

Critical Reasoning
Magazine ad: Men and women who run competitively learn that at least two of their human capabilities-physical stamina and breath control-can be stretched to higher and higher levels. The vigorous conditioning runners undergo is critical to their performance. Proper conditioning can also stretch another human capability-our minds. If you rigorously condition your mind, it can also attain higher and higher levels. Stretch and stimulate your mind! Join your local Puzzlemaster Club. This magazine ad uses which one of the followingstrategies in its approach?

(A) The ad relies on the results of experiments to suggest that joining a Puzzlemaster Club will have the effect of improving mental abilities.
(B) The ad ridicules people who don't join a Puzzlemaster Club by suggesting that they don't want to improve their minds.
(C) The ad explains why becoming a member of a Puzzlemaster Club will stretch and stimulate your mind.
(D) The ad supports or justifies its goal, i.e., that people join a Puzzlemaster Club, by carefully documenting the benefits of competitive running.
(E) The ad implies that because physical stamina, breath control and the mind are all human capabilities, our minds can be stretched to higher levels just as stamina and breath control can be stretched.

So,folks here are the correct answers

Critical Reasoning
The correct answer is E.

This magazine ad draws parallels between one human capability-the mind-and two other human capabilities-physical stamina and breath control. It suggests that because competitive runners who condition properly can stretch their stamina and breath control, proper conditioning can also stretch this third capability-the mind. Hence option (E) is the correct answer.

Quantitative Ability
The correct answer is B.

Since the HCF of x and y is 12, let x=12a and y=12b, where a and b are co-primes.
We have x+y=240 i.e. a+b=20.
Also, LCM of x and y will be 12ab, which is given as 1188.
Thus, 12ab=1188 i.e. ab=99
Finally, a+b=20 and ab=11 where a and b are co-primes.
Hence they must 11 and 9.
Thus the smaller number is 12×9 = 108.
