PUZZLE 1

Certain number of persons is living on the different floors of certain buildings that are in a row. The room numbers in each building are consecutive multiples of a room number, which is lowest of its own respective building. Each building has different number of floors and maximum number of floors a building can have is 7. Only one room is there on each floor and only one person lives on each floor. The maximum room number in which a person is living is 42. Only one room number is same for two rooms, which belong to different buildings. There are at most three buildings. There is no vacant floor in any of the buildings. No room number is 0. The heights of any floor of any of the building are same. The following information is known about them,

B, whose room number is 28, lives on a floor which is just below X’s floor, which is not adjacent to V’s floor. One of the person(s) who live(s) to the west of the floor of D, whose room number is 12, has room number as 21. E’s room number is 30 more than Q’s room number. Q lives on the floor just above E’s floor but not adjacent to F’s floor. V’s floor is to the west of A’s floor. A, whose room number is 21 lives on a floor that is four floors above D’s floor. F, whose room number is 20, is in the south-east of U and lives on the topmost floor of his building. R, whose room number is 9, lives on the floor that is two floors above T’s floor, whose room number is 6 more than that of D and 3 more than Y’s room number. Y is in north-east of U, who has lowest room number of his building. P has room number 30 and lives in the west of S. Y’s floor is immediately below or immediately above of Z’s floor, whose room number is not the lowest of his building. C’s floor is below W, whose floor is below the one, whose room number is 35.

PUZZLE 2

6 bank aspirants- P, Q, R, S, T and U prepared and practiced for a month. Before preparation, each of them took a note of their marks and after one month, they took a note of their respective marks. None of them has the same marks before or after preparation for the bank exam. It is known that:

P, who had more marks than both Q and R before preparation, had more marks than only one among Q and R after one month.

The rank difference of S and P is same. [Rank difference denotes the difference in rank when arranged according to marks, before preparation and after one month of an individual, where rank 1 is given to the highest scoring person and rank 6 is given to the lowest scoring person.]

Anyone who had more marks than U before preparation had not scored lesser than U after one month of preparation.

S, who scored more than R but lesser than T before preparation, had scored more than U after one month.

T scored neither the highest nor the lowest in both the cases (before and after preparation).

Q scored more than R before preparation.

After one month, exactly two persons among all the persons who scored less than U before preparation, scored more than U.

After one month of preparation, S scored lesser than all the persons, who scored lesser than S before preparation.

U did not score the highest before preparation or the lowest after one month of preparation.

P’s marks were not higher than S in both the cases together, though his marks may be lesser than S in both the cases.

PUZZLE 3

Eight boxes marked B01 to B08 are kept one above others in the form of stack, not necessarily in the same order. Each box is wrapped with different color viz.- Red, Cyan, Green, Black, Blue, Pink, Yellow and Brown. Each box also contains pens of different color viz.- Red, Cyan, Green, Black, Blue, Pink, Yellow and Brown. Number of pens in each box is multiple of position of box just above it between 1 to 60. None of the boxes contains same number of pens nor color of box and the color of pens are same.

For Example: If Box XYZ is kept at bottom, then it only contains number of pens multiple of 2 and box at top contains number of pens multiple of 9.

Two boxes are kept between the box B04 and the Cyan box, which contains 45 pens. Number of boxes above the box B07 is two more than the number of boxes below the box having Green pens. There are 16 Brown pens and kept three places from Black box. The box which contains 45 pens is kept just below Red box. Difference of the number of pens in the Blue box and the box B06 is 24. Black box is kept just above B07, which neither contains Red pen nor wrapped with Yellow. Two boxes are kept between the box which contains Blue Pen and the Pink box, which contains 21 pens. Number of boxes between the box B04 and the box B07 is same as number of boxes between the box B05 and Blue box. The box B05 neither contains odd number of pen nor kept adjacent to Green Box. Sum of the number of pens in the Blue box and Yellow box is equal to number of pens in the Red box. Pink box and Blue box are not kept together. The box B02 contains Red pen and is kept three places away from B03. Yellow box is kept at any place above the box having Pink Pen but below the box B08. Number of pens in the box B08 is cube number and is kept just above the Yellow Pen. Number of pens in the Brown box is half the number of Cyan pen. B05 is placed below B07.B05 is not placed a box which has a multiple of 2 and multiple of 5.

Critical reasoning:

6) Read the passage given below and select the inference(s) that hold true based on the facts in the passage.

Passage: That truth matters to science is hardly news. For a long time, people have looked to science for truths about the world. The Scientific Revolution was nothing if not the triumph of Galileo’s scientific truth – hard-won through his telescopic observations – over centuries of dogma about the geocentric system. With its system of epicycles and deferents, Ptolemaic astronomy was at once sophisticated and false. It served to, at best, ‘save the appearances’ about how planets seemed to move in the sky. It did not tell the truth about planetary motion until the discovery of the Copernican explanation.

Inferences:

I). Science is based and works on truth.

II). Galileo’s scientific triumph helped deprecate Ptolemaic astronomy.

III). Copernican explanation uncovered the fallacy of Ptolemaic astronomy and the truth about planetary motion.

A) Only inference I is true.

B) Only inference II is true.

C) Both I and II are true.

D) All of them are true.

E) None of them is true

Directions (7): Read the passage given below and choose the correct option.

7) Passage: In a recently published report on the condition of health of women in India, it is reported that while sanitation in urban houses has improved by 70%, in rural areas, still unsanitary habits contribute greatly towards malnutrition which has retarded the growth of 50 million children in our country. 70% of the health-related problems faced by the children of primary schools are due to insufficient sanitation. Polluted air and unsanitary habits result in disease through which approximately 4 lakhs children die every year.

Assumption: India’s poverty is responsible for the spreading of disease.​

A) If the assumption is definitely true.

B) If the assumption is probably true.

C) If the assumption is definitely false.

D) If the assumption is probably false.

E) If the data are inadequate.

8) Passage: Pollution amounts to slow murder. Regular exposure to industrial and vehicular pollution leads to life-threatening diseases like asthma, heart problems, cancer and various other disorders. Therefore, nobody has the right to pollute, rich or poor. Industrial and vehicular pollution is growing rapidly across the country. It is not just the metropolitan centre’s that are heavily polluted today but also small and medium towns. Pollution is growing faster than the economy. This is because the western technological model, built on heavy use of energy and materials, is an inherently highly toxic model. It produces huge amounts of toxic pollution, which can be controlled only if there is a careful choice of technology and there is considerable discipline in its use.

Assumption: The pollution level in the western world is considerably more than that in India.​

A) If the assumption is definitely true.

B) If the assumption is probably true.

C) If the assumption is definitely false.

D) If the assumption is probably false.

E) If the data are inadequate.

Reverse syllogism

Directions (9-10): In the questions below are given some conclusions followed by five sets of statements. You have to choose the correct set of statements that logically satisfies given conclusions definitely .Assume the given statements to be true even if they seem to be at variance from commonly known facts.

9) Conclusions: 

Some dark is white.

Some black is not white.

Statements:

(a) Some black is green. No green is white. Some white is fair. All fair is dark. No dark is violet.

(b) Some black is white. All white is green. No green is fair. Some fair is dark. All dark is violet.

(c) Some fair is dark. All dark is violet. No violet is black. Some black is white. All white is green.

(d) Some fair is violet. All violet is dark. No dark is black. All black is white. Some black is green.

(e) None of these.

10) Conclusions:

Some wind is air.

Some air is sky.

Statements:

(a) Some sky is air. All airs are blue. Some blue is tree. All trees are wind. Some trees are nose.

(b) Some sky is tree. All trees are wind. Some wind is nose. All noses are blue. Some blue is air.

(c) Some sky is nose. All noses are blue. Some blue is air. All airs are tree. Some tree is wind.

(d) All sky is blue. Some sky is air. Some air is tree. All trees are wind. Some wind is nose.

(e) None of these.

BLOOD RELATION: 


4.E

5.D

6) Answer: D

The entire passage implies that science is governed by truth. Hence, inference I is true. The words ‘triumph’ and ‘over’ in the third statement suggests that Galileo’s scientific truth did help deprecate or devalue the geocentric system i.e. the Ptolemaic astronomy. Hence, inference II is also true. The last line in the passage says that Copernican explanation told the truth about planetary motion and uncovered that Ptolemaic astronomy was false. So, inference III is also true. Therefore, option d is the correct answer.

7) Answer: C

Option c is the correct answer. The passage talks about how unsanitary methods contribute to the deaths of approximately 4 lakh children every year. It does not mention poverty at all. Hence, the assumption is definitely false.

8) Answer: E

Option e is the correct answer. It is possible that Western countries practice discipline in the use of technology and choose it carefully. So nothing can be assumed about the pollution level in the western world on the basis of the given passage. Data are inadequate.
