Answer is B (14%).

I think in the 1st line of the question, the word ‘who’ should be inserted between ‘interns’ and ‘receive’ as it is given in later part of the question that 80% of interns receive less than 6 hours of sleep. Hence, 20% of interns receive 6 or more hours of sleep.

Interns complaining of fatigue = 75% of 80% of total interns = 60% of interns

Hence, interns who don’t complain of fatigue = 70% of (balance 20% of total interns) = 14% of interns

C & B.

PS: Let m be the no. of males and f be the no. of females last year.

So, total members last year = m + f

Total members this year = 1.1 (m+f)

Now, it is given that 1.1 (m+f) = 1.05 m + 1.2 f

Hence, 0.05 m = 0.1 f

or m = 2f

Fraction of females to total members of soccer league this year = 1.2f/(1.1m+1.1f)

Substituting m=2f, we get the desired fraction as = 1.2f/3.3f = 1.2/3.3 = 12/33 = 4/11

So, answer is B.

SC: E &

Problem solving: C (0.8)

Solving, we get a(b+10a)+b(a+10b)=2b(b+10a)

or ab+10a^{2+ab+ 10b}2=2b^2+20ab

or 10a2+8b^2-18ab=0

Dividing the equation by ab, we get:

10a/b+8b/a-18=0

Let a/b=k, we get:

10k+8/k-18=0, or

10k2-18K+8=0, or

5k^2-9k+4=0

Solving for k, i.e a/b, we get k = a/b = 0.8

Sentence Completion: E.

Quantitative Comparison: B. It is easier once Col. B is rewritten as 6/30 or (1/30 + 1/30 + 1/30 + 1/30 + 1/30 + 1/30). As 1/30 > any of the 6 individual elements in Col.A, 6/30 or 1/5 will naturally be > sum of the 6 elements in Col.A.

great inspirational poem! it’s all really inside! thanks for posting it!

Thanks for your comments and I agree with your useful input!

Great compilation of phobias! but the list can never be said to be complete as i think there could be as many phobias as there are things or ideas in the world – real as well as imaginary!

Dear Suresh, the alternative approach given by you is also good. Actually, i think it mostly depends on the person which approach seems easier to him.

great tips Rabindra! thanks for posting them.

I think this may be an easy manner to solve the above problem -

(A+B+C)’s one day’s output = 1/15, hence their 2 days’ output = 2/15 ——(1)

C’s one day’s output = 1/75, C’s 40 days’ output = 40/75 = 8/15

Hence, balance work done by B & C (in 10 days) = 1- (2/15) – (8/15) = 5/15 = 1/3

Hence, per day output of (B + C) = (1/10) x (1/3) = 1/30 — (2)

From (1) & (2) above, we get per day output of A alone = (1/15) – (1/30) = 1/30

Hence, A can alone complete the whole work in 30 days.

In problem 2, ideally, no equation is required -

Work done by Ramya alone in 5 days = 5 x (1/30) = 1/6

Hence, balance work after 5 days = 5/6

Together, Ramya & Subha can complete the entire work in 12 days ( 1/(1/20+1/30) )

Hence, time required to complete balance work (5/6) together = 12×5/6 = 10 days

I partly agree with the views expressed here. As far as writing in one’s personal diary is concerned, one can afford to record in a more casual (at least i think so in my case) and brief manner some important events of one’s day to day or personal/social/professional life and occasional strong ideas/emotions that come to mind from time to time. Here, i believe, the main purpose is to just have a brief chronological record of events you consider personally important to you, for your own reference (i occasionally refer :)) at a later stage and not for publicity.

I agree that it is another matter that such record of events could serve as a very important guide to facilitate creation of more serious creative works, including but not limited to writing one’s own autobiography, which may or may not be intended for general/wider/limited publicity.

Thanks for posting this thought provoking story, Tiffany! I can understand and must appreciate the dilemma in your mind after reading this story as to what is real and what is not! Without going into any philosophical discussion, all I would say is that the way the humans behave, physically and emotionally, is no better or may be worse than how the robots have been shown to behave in the story AND as you rightly wonder, with technology and other material comforts, the situation is not becoming better as regards the human loneliness.

To be brief and not sounding too complicated, i would say, the situation above is so because of our seeking the pleasure and love in material things, outside of our own/real self that is self-fulfilling/luminous. The need to dive to the depths ‘within’ to discover that real self and real love, attaining which the reliance on the outside/fleeting things (including what one considers his own mind and intellect) will vanish, impliedly gets reaffirmed thru’ this story! Thanks again and God bless you.

My pleasure! Thanks.

I agree! I sort of become emotional, but encouraged, after being reminded of the deep thoughts and philosophy conveyed in this lovely prayer! Thanks a lot Eleonor for your comments.

Thanks for your kind encouragement, Tiffany.

Ok, i think that my concern has now been attended to some extent!

Thanks Suresh.

Don’t find IIT, Delhi in this list? Also, i believe that the list is not in the order of ranking of the College!

Interesting! Got this one from a friend. Here it goes -

Equation 1

Human = eat + sleep + work + enjoy

Donkey = eat + sleep

Therefore,

Human = Donkey + work + enjoy

Therefore,

Human – enjoy = Donkey + work

In other words,

Human that don’t know enjoy = Donkey that work

Equation 2

Men = eat + sleep + earn money

Donkeys = eat + sleep

Therefore,

Men = Donkeys + earn money

Therefore,

Men – earn money = Donkeys

In other words,

Men that don’t earn money = Donkeys

Equation 3

Women = eat + sleep + spend

Donkeys = eat + sleep

Therefore,

Women = Donkeys + spend

Therefore,

Women – spend = Donkeys

In other words,

Women that don’t spend = Donkeys

To Conclude:

From Equation 2 and Equation 3

Men that don’t earn money = Women that don’t spend.

So, Men earn money not to let women become Donkeys! (Postulate 1)

And, Women spend not to let men become Donkeys! (Postulate 2)

So, we have?

Men + Women = Donkeys + earn money + Donkeys + spend money

Therefore from Postulates 1 and 2, we can conclude,

Man + Woman = 2 Donkeys that live happily together!
