4. Box P is placed immediately above box R.

 

5. The box just below box S is placed three positions below box V.

 

6. Box Q is placed below box T. 

This is our final arrangement,

 

Hence, the correct answer is Q.

Given: Seven boxes, namely, P, Q, R, S, T, U, and V, are stacked vertically, where position 1 is the bottom and position 7 is the top.

Given word: COVALENT.

Forward pair: LN

Backward pair: LO

Thus, there are two such pairs of letters in the word "COVALENT" which have as many letters between them as in the English alphabetical series (both in backward and forward directions).

Hence, the correct answer is two.

Given: A certain number of persons sit on a linear row facing towards north direction. 

1. R sits three places away from V who sits at the one of the end position.

2. Three persons sit between R and F.

3. One person sits between F and M who sits to the left of F.

4. Two persons sit between S and M who sits to the right of S.

5. S sits third to the right of Q. Therefore, case 1 is eliminated.

6. The number of persons sit to the left of Q is two less than that of to the right of F.                     

7. Q sits four places away from K.

8. K and S do not sit adjacent to each other. Hence, the final arrangement is as follows

Hence, nine persons sit between K and M.

Given: A certain number of persons sit on a linear row facing towards north direction. 

1. R sits three places away from V who sits at the one of the end position.

2. Three persons sit between R and F.

3. One person sits between F and M who sits to the left of F.

4. Two persons sit between S and M who sits to the right of S.

5. S sits third to the right of Q. Therefore, case 1 is eliminated.

6. The number of persons sit to the left of Q is two less than that of to the right of F.                     

7. Q sits four places away from K.

8. K and S do not sit adjacent to each other. Hence, the final arrangement is as follows

Since, K sits to the left of Q not to the right. Therefore, statement I is incorrect.

Five persons which is a prime number sit to the left of Q. Therefore, statement II is correct.

S sits exactly between M and Q. Therefore, statement III is correct.

Hence, the correct answer is only II and III.

Given: A certain number of persons sit on a linear row facing towards north direction. 

1. R sits three places away from V who sits at the one of the end position.

2. Three persons sit between R and F.

3. One person sits between F and M who sits to the left of F.

4. Two persons sit between S and M who sits to the right of S.

5. S sits third to the right of Q. Therefore, case 1 is eliminated.

6. The number of persons sit to the left of Q is two less than that of to the right of F.                     

7. Q sits four places away from K.

8. K and S do not sit adjacent to each other. Hence, the final arrangement is as follows

Hence, F sits fifth to the right of S.

The least possible diagram for the given statements is as follows

Conclusions:

I. No twitter is facebook. → False (It is possible but not definite)

II. Some twitter is facebook. → False (It is possible but not definite)

Both are complementary conclusions.

Hence, either I or II follows

The least possible Venn diagram is as follows,

Conclusions:

I. Some cats are not horses is a possibility → Possibility is true.

II. Some dogs are not rats → True.

Hence, both conclusions I and II follows.

The least possible Venn diagram is as follows:

Conclusions:

I. Some White are Gold → False (As there is no direct relation between White and Gold. It is possible but not definite. So, it is false)

II. Some Gold are Black → False (As there is no direct relation between Black and Gold. It is possible but not definite. So, it is false)

Hence, Neither conclusion I nor II follows.

1. Some Nest is Mouse → False (As All Bird is Nest, all part of Bird means Mouse is Nest. So, it is false)

2. Some Mouse is Bird → True (As All Mouse is Bird → Some Mouse is Bird. So, it is true)

3. All Rabbit is Mouse is possible → False (Some rabbit are not mouse. So, All Rabbit will not be Mouse. so, it is false)

Hence, Only conclusions 1 and 3 does not follow here.

Given series:

Left side ¥ R 6 # J K 4 @ 5 L 7 * 1 M N $ J H £ G 9 © right side

 As, left – left = left

9^th from the left – 5^th from the left = 4^th from the left

Clearly, 4^th from the left is #$.

Given series:

Left Side ¥ R 6 # J K 4 @ 5 L 7 * 1 M N $ J H £ G 9 © Right Side

1. Symbols which are immediately preceded by a number and followed by an alphabet:

¥ R 6 # J K 4 @ 5 L 7 * 1 M N $ J H £ G 9 ©

Hence, there is 1 symbol which is immediately preceded by number and followed by an alphabet: 6 # J

Given series:

Left Side ¥ R 6 # J K 4 @ 5 L 7 * 1 M N $ J H £ G 9 © Right Side

After removing the alphabets and symbols will get the series as 6 4 5 7 1 9

The ascending order is 1 4 5 6 7 9. Hence option 2 is correct$.

Given series:

Left Side ¥ R 6 # J K 4 @ 5 L 7 * 1 M N $ J H £ G 9 © Right Side

​1) If all the symbols are dropped:

R 6 J K 4 5 L 7 1 M N J H G 9

2. 10^th letter/number from the right end is 5.

Then, letter/ number that is tenth from right end is ‘5’$.

Given series:

Left Side ¥ R 6 # J K 4 @ 5 L 7 * 1 M N $ J H £ G 9 © Right Side

Symbols which are immediately followed by a number and preceded by a number:

 ¥ R 6 # J K 4 @ 5 L 7 * 1 M N $ J H £ G 9 ©.

Hence, there are two sets which are immediately followed by number and preceded by number.

Given: Seven individuals, namely, X, P, L, R, M, T, and Y, are planning a vacation to Canada, each traveling in a different month among March, April, May, June, July, August, and September, but not necessarily in this order.

1. R travels in a month that has 31 days.

Here, we have 3 Cases, i.e., Case 1, Case 2, Case 3, and Case 4.

 

2.  Exactly three people travel between R and Y.

 

3. There are two people between P and Y.

 

4. P travels earlier than R.

Now, we can eliminate Case 1 and Case 2.

 

5. Two people travel between R and L.

 

 

6. T travels immediately after L.

 

 

7. X does not travel in a month that has 30 days. 

 

8. X does not travel before P. 

Now, we can eliminate Case 4.

This is our final arrangement,

 

Hence, the correct answer is R.
