Disabuse : Error

Detailed Solution for BITSAT Logical Reasoning Test - 10 - Question 4

The first word leads to elimination of the second word. 'Disabuse' means to free someone of 'error', misconception, or fallacy and 'discredit' means to deprive one of one's reputation. Option 2 shares the same relation and is the correct answer.
(1) - 'Persevere' means to continue in a course of action even in the face of difficulties. 'Dereliction' means shameful failure to fulfil one's obligations.
(3) - 'Exonerate' means to absolve (someone) from blame for a fault or wrongdoing. 'Addiction' is an unrelated word.
(4) - 'Asperse' means to attack or criticize someone's reputation or integrity. 'Imperfection' is an unrelated word.
(5) - 'Parry' means to ward off (a weapon or attack) with a countermove. 'Blitz' means an intensive or sudden military attack.

Six roads lead to a country. They are indicated by letters X, Y, Z and digits 1, 2, 3. When there is a storm, Y is blocked. When there are floods, X, 1 and 2 will be affected. When road 1 is blocked, Z is blocked as well. At a time when there are both floods and storms, which road(s) can be used?

Detailed Solution for BITSAT Logical Reasoning Test - 10 - Question 7

Due to the storm, road Y is blocked.
Due to the floods, roads X, 1 & 2 are affected.
Hence, road Z also gets blocked.
At a time when there are both floods and storms, X, Y, Z, 1 and 2 can not be used.
So, only road 3 can be used.

BITSAT Logical Reasoning Test - 10 - Question 8

Seven men, A, B, C, D, E, F and G are standing in a queue in that order. Each one is wearing a cap of a different colour like violet, indigo, blue, green, yellow, orange and red not particularly in that order. D is able to see in front of him green and blue but not violet. E can see violet and yellow, but not red. G can see caps of all colours other than orange, if E is wearing an indigo coloured cap, then the colour of the cap worn by F is

Detailed Solution for BITSAT Logical Reasoning Test - 10 - Question 9

A person can see caps of all persons standing in front of him but can't see his own cap and caps of persons standing behind him.

Given that E wears indigo cap.
D is able to see in front of him green and blue, but not violet which means the people in front of D i.e., A or B or C wore green or blue and people after D and including himself i.e., D or E or F or G wore violet. E can see violet and yellow but not red.

Clearly, D is wearing violet cap and A/B/C wore green/blue/yellow not necessarily in that order. G can see caps of all colours other than orange which means he is the last person in the row, he can see all caps except his. So, we can say G is wearing orange cap.

So, we can summarise all this information in a table

Finally, we are left with red cap which means F is wearing it.

No person can serve on more than one committee.
H must serve on the entertainment committee.
C and D must serve on the same committee.
A and B cannot serve on the same committee.
E cannot serve on the same committee as I.
F must serve on the committee as B or H or both B and H.

If B and G serve on the Game Committee, which of the following must serve on the Food Service Committee?

Detailed Solution for BITSAT Logical Reasoning Test - 10 - Question 10


Left Members are ADEC and I.
Now A and B should be separate. Let us assume that A is in Entertainment committee and C and D have to be together so we place them in food committee. E and I have to be separate so we can place E in entertainment committee.
Hence D is in the food committee

BITSAT Logical Reasoning Test - 10 - Question 11

A, B, C, D and E are standing in a line facing north. C stands in the middle. B and E cannot stand with C. A is not standing to the right of C. Who is standing second from the left end?

From the above table, it is clear that A likes to go the clubs on Tuesday whereas B goes on Friday, C on Wednesday, D on Saturday, E on Sunday, F on Thursday and G on Monday. So, the required answer is A as per this above table and he/she  has Mahindra car.

BITSAT Logical Reasoning Test - 10 - Question 16

On the basis of two figures of dice, you have to tell what number will be there at the bottom, if 5 is at the top?

Detailed Solution for BITSAT Logical Reasoning Test - 10 - Question 16

In this question, we have given two dices. Now, we have to find out the number on the opposite side of the number given in the question.
From the figure, first observed the common number between two dices.
Hence, 2 is the common number between the two dices, so arrange the number by rotating the numbers in the clockwise direction from the common number e.g 2. And the other two pairs thus formed will be the opposite.
Now,
From figure 1 − 2 4 1
From figure 2 − 2 6 3
Here, 4 is opposite to 6 and 1 is opposite to 3.5 is the only number left so if 5 is at the top then 2 is at the bottom.
Hence, the correct answer is option B.

BITSAT Logical Reasoning Test - 10 - Question 17

The given two positions are of the same dice whose each surface bears a number among 1, 2, 3, 4, 5, and 6. What number is at the opposite of 3 in the figure shown below?

Detailed Solution for BITSAT Logical Reasoning Test - 10 - Question 17

In this question, we have given two dices.
We have to find out the number on the opposite side of the number given in the question.
From the figure, observed the common number between two dices.
5 is the common number between the two dices, so arrange the number by rotating the numbers in the clockwise direction from the common number e.g 5.
The other two pairs thus formed will be the opposite.
Now,
From figure 1 − 5 6 2
From figure 2 − 5 1 4
Here, 3 will be the opposite of 5.
So, 5 is the correct option.
Hence, the correct answer is option C.

BITSAT Logical Reasoning Test - 10 - Question 18

Which number is on the face opposite to face having number 1?

Detailed Solution for BITSAT Logical Reasoning Test - 10 - Question 18

In this question, we have given three dices.
Now, we have to find out the number on the opposite side of the number given in the question.
From all the figure, we made a complete figure by taking one of the figures, which satisfy all three figure.

Thus 2 is opposite to 6. (from the first and second figure).
4 is opposite to 5. (from the first and last figures).
Hence, 1 is opposite to 3.
So, the correct answer is option B.
Thus, the option B is the correct answer.

BITSAT Logical Reasoning Test - 10 - Question 19

Which alphabet will come on the opposite surface of which alphabet F will appear?

Detailed Solution for BITSAT Logical Reasoning Test - 10 - Question 19

In this question, we have given three dices. Now, we have to find out the letter on the opposite side of the letter given in the question.
From all the three-figure, we took first as a reference figure and made the main figure as follows.

Using 1st and 3rd figure we get A opposite to D.
Using the second and third figure we get E opposite to B.
Hence, C comes opposite to F.
So, the correct answer is option C.

BITSAT Logical Reasoning Test - 10 - Question 20

Two positions of a dice are shown below. Identify the number at the bottom when the top is 3?

Detailed Solution for BITSAT Logical Reasoning Test - 10 - Question 20

In this question, we have given two dices. Now, we have to find out the number on the opposite side of the number given in the question.
From the figure, first observed the common number between two dices.
Hence, 6 is the common number between the two dices, so arrange the number by rotating the numbers in the clockwise direction from the common number e.g. 6. And the other two pairs thus formed will be the opposite.
Now,
From figure 1−6 4 5
From figure 2−6 1 3
Here, 4 is opposite to 1 and 5 is opposite to 3. So, if 3 is at the top then 5 is at the bottom.
Hence, this is the correct answer.
