Pls explain the below que -

58.Consider the following relations, R and S, defined on the set A = {1, 2, 3}:

R = {(1, 1), (1, 3), (2, 2), (3, 1), (3, 3)}
S = {(1, 1), (1, 2), (2, 2), (2, 1), (2, 3), (3, 2), (3, 3)}

Which of the following statements is/are true?

a)Both R and S are equivalence relations

b)R ∩ S is an equivalence relation.

c)R  S is an equivalence relation.

d)Both (B) and (C).

VENN DIAGRAM ::  Last Set Qs 21-24 AIMCAT 1708

"The number of students in Class 8 who like only Mathematics is the same as the number of students in Class 9 who like both Science and Social."

The solution provided by TIME transforms this statement to a8  = f9 + g9 where a8 is students ho took only mathsin class 8 , f9 is students who study science and social in class 9 while g9 is students who study maths, science and social in class 9.

Query - Shouldn't a8 = f9 only? Why is g9 included here?

P.S- I am finding the statements in Venn Diagram quite confusing. Most of the times, this edge case- to select the common area of 3 parameters- is to be taken or not is causing issues.

Need some expert opinion here....

yes, same here. The sentence construction is vague

DIRECTIONS for questions 5 to 8: The passage given below is followed by a set of four questions. Choose the best answer to each question.

In Lewis Carroll’s Through the Looking-Glass, Alice meets the White Queen, who lives in both directions of time. The Queen is shouting and shaking her finger in pain:

“What IS the matter?” [Alice] said, “Have you pricked your finger?”

“I haven’t pricked it YET,” the Queen said, “but I soon shall – oh, oh, oh!”

“When do you expect to do it?” Alice asked.

“When I fasten my shawl again,” the poor Queen groaned out: “the brooch will come undone directly. Oh, oh!” The brooch flew open, and the Queen clutched wildly at it, and tried to clasp it again.

“Take care!” cried Alice. “You’re holding it all crooked!” And she caught at the brooch; but it was too late: the pin had slipped, and the Queen had pricked her finger.

Reversing the relative direction of time never happens in the actual, non-imaginary world. The psychological arrow of time is the direction in which we feel time passes, where we remember the past but not the future. None of us has met a character like the White Queen, who remembers what we think of as “the future” rather than (or in addition to) “the past.”

What does it mean to say that time has a direction, an arrow pointing from the past to the future? Think about watching a movie played in reverse or seeing something running the “wrong way” in time. A classic example is a diver and a pool. If the diver dives, and then there is a big splash, followed by waves bouncing around in the water, all is normal. But if we see a pool that starts with waves, which collect into a big splash, in the process lifting a diver up onto the board, we know the movie is being played backward. Incidentally, F. Scott Fitzgerald’s short story “The Curious Case of Benjamin Button” features a protagonist who is born as an old man and gradually grows younger.

Certain events in the real world always happen in the same order. It’s dive, splash, waves; never waves, splash, spit out a diver. Take milk and mix it into a cup of black coffee; never take coffee with milk and separate the two liquids. Sequences of this sort are called irreversible processes.

Irreversible processes are at the heart of the arrow of time. Events happen in some sequences, and not in others. Furthermore, this ordering is perfectly consistent throughout the observable universe. Someday we might find a planet in a distant solar system that contains intelligent life, but nobody suspects that we will find a planet on which the aliens regularly separate (the indigenous equivalents of) milk and coffee with a few casual swirls of a spoon. Why isn’t that surprising? It’s a big universe out there; things might very well happen in all sorts of sequences. But they don’t. For certain kinds of processes, there seems to be an allowed order that is somehow built into the very fabric of the world.

The arrow of time is the brute fact about our universe; the fact that things happen in one order and not in the reverse order is deeply ingrained in how we live in the world. Why is it like that? Why do we live in a universe where X is often followed by Y, but Y is never followed by X?

The answer lies in the concept of “entropy”. Like energy or temperature, entropy tells us something about the particular state of a physical system; specifically, it measures how disorderly the system is. The entropy of a cup of coffee along with a separate teaspoon of milk is low, because there is a particular orderly segregation of the molecules into “milk ” and “coffee,” while the entropy of the two mixed together is comparatively large. All of the irreversible processes that reflect time’s arrow – we can turn eggs into omelets but not omelets into eggs, perfume disperses through a room but never collects back into the bottle, ice cubes in water melt but glasses of warm water don’t spontaneously form ice cubes – share a common feature: Entropy increases throughout, as the system progresses from order to disorder. Whenever we disturb the universe, we tend to increase its entropy. The reason why entropy wants to increase is deceptively simple: There are more ways to be disorderly than to be orderly, so (all else being equal) an orderly arrangement will naturally tend toward increasing disorder. And if everything in the universe evolves toward increasing disorder, it must have started out in an exquisitely ordered arrangement. This whole chain of logic, purporting to explain why you can’t turn an omelet into an egg, apparently rests on a deep assumption about the very beginning of the universe: It was in a state of very low entropy, very high order.

Which of the following can be inferred from the passage?

Aliens are more intelligent than humans and can make irreversible things happen.
Aliens, no matter how intelligent, cannot make irreversible processes reversible
The laws governing irreversible processes are the same throughout the universe.
Humans are not capable of imagining aliens that are capable of reversing irreversible processes.

With my body temperature 4 degrees above normal, I foolishily continued giving the mock and ended up with my worst rank of the season. Nevertheless, thank God this wasn't the Day!

Ques 56 QA:

circle C1, C2 and PQ and XY joining centres...they wanted minimum possible area...why can't X or Y coincide with P or Q.....line joining centres cuts the circles...can't d point of intersection nd d centre b same point??

dey had no option matching dis....any help pointing my fault???

Nope. PQ = 2cm and Radius was 3cm. So the intersection point cannot pass through the center.
