Question 3
1 / -0

Direction:In the following question assuming the given statements to be true, find which of the conclusion among the given conclusions is/ are definitely true and then give your answers accordingly.

Statements: G ≥ M = P > C; Q < R = B < C

Conclusions:

I. M > R

II. G ≥ B

A
Only I follows

B
Only II follows

C
Both I and II follow

D
Either I or II follows

E
None of these

Solution

Given statements: G ≥ M = P > C; Q < R = B < C

On combining above two statements: G ≥ M = P > C > B = R > Q

Conclusions:

I. M > R → True ( as M = P > C > B = R)

II. G ≥ B → False ( as G ≥ M = P > C > B → G > B)

Therefore only conclusion I follows.

Question 4

1 / -0

Direction: Question below consists of a question and two statements numbered I and II given below it. You have to decide whether the data provided in the statements are sufficient to answer the question.

Six friends - A, B, C, D, E and F had meeting on either 15th or 18th of three different months – January, March and April. But not necessarily in the same order. Whose meeting is on March 15th?

Statement I: Four people had meeting between E and F. Two people had meeting between B and F, who did not have meeting on January 15th.

Statement II: A had meeting before D and C. D had meeting immediately before C.

If the Question can be answered By the Statement I alone but not by the statement II alone.

If the Question can be answered by the Statement II alone but not by the Statement I alone.

If the Question can be answered by using either statement alone.

If the Question can be answered by using both the statements together, but cannot be using either Statement alone.

If the Question cannot be answered even by using both the statements together.

Solution

According to the given information,

Names of person: A, B, C, D, E and F

Date's of meeting: 15th or 18th of three different months – January, March and April.

Statement I: Four people had meeting between E and F. Two people had meeting between B and F, who did not have meeting on January 15th.

(Here, as four people have meeting between E and F, and F did not have meeting on January 15th. So, F will have meeting on April 18th. Two people had meeting between F and B, so B has meeting on March 15th)

Month	Date	Person
January	15th	E
January	18th
March	15th	B
March	18th
April	15th
April	18th	F

So, the Question can be answered By the Statement I.

Statement II: A had meeting before D and C. D had meeting immediately before C.

Arrangement is not possible in this case.

So, the Question can be answered By the Statement I alone but not by the statement II alone.

Solution
Question 7
1 / -0

Direction: In the question below are given two statements followed by two conclusions I and II. You have to take the given statements to be true even if they seem to be at variance from commonly known facts. Read all the conclusions and then decide which of the given conclusions logically follows from the given statements disregarding commonly known facts.

Statements:

Some electricians are plumbers.

Only a few plumbers are mechanics.

Conclusions:

I. At least some mechanics are not plumbers is a possibility.

II. All electricians are mechanics is a possibility.

A
Only II follows

B
Only I follows

C
Both I and II follow

D
Either I or II follows

E
Neither I nor II follow

Solution

The least possible Venn diagram for the given statements is as follows,

Conclusions:

I. At least some mechanics are not plumbers is a possibility → True (Only a few plumbers are mechanics)

II. All electricians are mechanics is a possibility → True (Possibility is true as shown below)

Thus, both conclusions I and II follow.
Question 8
1 / -0

Direction: In the following question assuming the given statements to be true, find which of the conclusion among the given conclusions is/are definitely true and then give your answers accordingly

Statement: P ≤ R = D > L = N; H A > C ≥ P

Conclusions:

I. L L = N; H A > C ≥ P

On combining above two statements: H A > C ≥ P ≤ R = D > L = N

Conclusions:

I. L A > C ≥ P ≤ R = D > L, so no clear relation can be established between L and R)

II. L ≤ I → False ( as I > A > C ≥ P ≤ R = D > L, so no clear relation can be established between L and R)

Therefore, none of the two conclusions follow.
Question 9
1 / -0

Direction: In each question below are given three statements followed by two conclusions numbered I and II. You have to take the given two statements to be true even if they seem to be at variance with commonly known facts and then decide which of the given conclusions logically follows from the statements, disregarding commonly known facts.

Statements:

Some bananas are soaps.

Some powders are soaps.

All detergents are powders.

Conclusions:

I. Some soaps are detergents.

II. No soaps are detergents.

A
Only I follows

B
Only II follows

C
Either I or II follows

D
Neither I and II follows

E
Both I and II follows

Solution

The least possible Venn diagram for the given statements is as follows.

Conclusions:

I. Some soaps are detergents → False (It is possible but not definite)

II. No soaps are detergents → False (It is possible but not definite)

Here some + not condition form a complementary pair.

Therefore, Either conclusion I or II follows.
Question 10
1 / -0

Directions For Questions

Direction: Study the given information carefully and answer the following questions below.

8 different boxes named as B, F, J, O, S, U, W and Z are placed in the shelves, but not necessarily in the same order. Only one box is placed in each shelf. There is a number written on each shelf from 1 to 8. Number 1 is written on the lowermost shelf, number 2 is written on the shelf which is immediately above the shelf 1 and others are accordingly. There are at least 5 shelves above the box Z. There are three boxes between box J and Z. Box B is placed two places above the box J. There are four boxes between the box B and F. There are three shelves between the box O and W. Box W is neither placed at the bottom nor on the top. Box S is placed on one of the shelves which is below the box U but not at even number.

...view full instructions

Which of the following is the correct position of box S?

A
Immediately above box Z

B
Immediately below box W

C
Two places below box U

D
Three places above box F

E
Placed at shelf 5

Solution

8 boxes: B, F, J, O, S, U, W and Z.

8 shelves: 1 to 8 (from bottom to top).

We can solve this question step by step,

1) There are at least 5 shelves above the box Z.

2) There are three boxes between box J and Z.

Case – 1

3) Box B is placed two places above the box J.

This condition doesn’t satisfy in case 1. Thus, case 1 gets eliminated.

4) There are four boxes between the box B and F.

Case – 2

5) There are three shelves between the box O and W.

6) Box W is neither placed at the bottom nor on the top.

Case – 2

7) Box S is placed on one of the shelves which is below the box U but not at even This number.

This condition doesn’t satisfy in case 2.

Thus, case 2 gets eliminated and we have the final arrangement as follows:

Case – 3

Since box S is placed immediately below box W.

So, ‘immediately below box W’ is the correct answer.
