Persons: Mano, Nisha, Ovya, Pami, Jamu, Kavi, Guna, and Hari

1. Ovya is sitting 2nd to the right of Kavi who is sitting opposite to the one who is an immediate neighbour of Hari who sits on the smaller side of the table.

2. Pami sits immediate left of Nisha and vice versa. So, Case 3 is eliminated.

3. Guna faces one of the immediate neighbours of Mano.

4. Ovya is not an immediate neighbour of Mano.

5. Jamu neither sits opposite to Nisha nor sits on the smaller side of the table. So, Case 2 and Case 1a is eliminated.

The final arrangement is,

Thus, Both I and III is the answer.

Given Names: Si, Ki, Te, To, Bi, Ci, and Ai

1. Only one person types faster than Ai but Ai types slower than Si. 

Si > Ai > ___ > ___ > ___ > ___ > ___

2. Not more than two persons types faster than Bi.

Si > Ai > Bi > ___ > ___ > ___ > ___

3. At least three persons type slower than Ci.

Si > Ai > Bi > Ci > ___ > ___ > ___

4. Ki types slower than at least four people.

Case 1:

Si > Ai > Bi > Ci > Ki > ___ > ___

Case 2:

Si > Ai > Bi > Ci > ___ > Ki > ___

Case 3:

Si > Ai > Bi > Ci > ___ > ___ > Ki 

5. Ki types faster than To but slower than Te.

(By this statement Case 1 and Case 3 are eliminated)

The final arrangement will be as follows:

Si > Ai > Bi > Ci > Te > Ki > To

Hence, ‘Si’ type fastest among all.

Given Names: Si, Ki, Te, To, Bi, Ci, and Ai

1. Only one person types faster than Ai but Ai types slower than Si. 

Si > Ai > ___ > ___ > ___ > ___ > ___

2. Not more than two persons types faster than Bi.

Si > Ai > Bi > ___ > ___ > ___ > ___

3. At least three persons type slower than Ci.

Si > Ai > Bi > Ci > ___ > ___ > ___

4. Ki types slower than at least four people.

Case 1:

Si > Ai > Bi > Ci > Ki > ___ > ___

Case 2:

Si > Ai > Bi > Ci > ___ > Ki > ___

Case 3:

Si > Ai > Bi > Ci > ___ > ___ > Ki 

5. Ki types faster than To but slower than Te.

(By this statement Case 1 and Case 3 are eliminated)

The final arrangement will be as follows:

Si > Ai > Bi > Ci > Te > Ki > To

Hence, ‘To’ types the slowest.

Given Names: Si, Ki, Te, To, Bi, Ci, and Ai

1. Only one person types faster than Ai but Ai types slower than Si. 

Si > Ai > ___ > ___ > ___ > ___ > ___

2. Not more than two persons types faster than Bi.

Si > Ai > Bi > ___ > ___ > ___ > ___

3. At least three persons type slower than Ci.

Si > Ai > Bi > Ci > ___ > ___ > ___

4. Ki types slower than at least four people.

Case 1:

Case 2:

Si > Ai > Bi > Ci > ___ > Ki > ___

Case 3:

Si > Ai > Bi > Ci > ___ > ___ > Ki 

5. Ki types faster than To but slower than Te.

(By this statement Case 1 and Case 3 are eliminated)

The final arrangement will be as follows:

Si > Ai > Bi > Ci > Te > Ki > To.

Hence, 69 wpm is the typing speed of Bi.

Now, as per the given information in the question we get the following direction diagrams:

1. F is 12 km to the west of G. U is situated exactly in the middle of F and G. Combining these two statements, we get-

2. U is 7 km to the south of S. S is 12 km to the east of O. Combining these two statements we get-

3. L is 7 km to the north of H. O is 6 km to the west of H. Combining these two statements we get the final direction diagram as follows-

From the above direction diagram, we see that branches F, U and G are located to the south-east of O and branch L is located to the north-east of O.

Hence, branch S is not located to the south-east or north-east of branch O.

Now, as per the given information in the question we get the following direction diagrams:

1. F is 12 km to the west of G. U is situated exactly in the middle of F and G. Combining these two statements, we get-

2. U is 7 km to the south of S. S is 12 km to the east of O. Combining these two statements we get-

3. L is 7 km to the north of H. O is 6 km to the west of H. Combining these two statements we get the final direction diagram as follows-

From the above direction diagram, we see that-

The distance between branch L and branch F is = 7+7 = 14 km

The distance between branch U and branch G is= 6 km

Therefore, the ratio between the two distances is 14 km: 6 km.

Hence, the required ratio between the two distances is 7:3.

Now, as per the given information in the question we get the following direction diagrams:

1. F is 12 km to the west of G. U is situated exactly in the middle of F and G. Combining these two statements, we get-

2. U is 7 km to the south of S. S is 12 km to the east of O. Combining these two statements we get-

3. L is 7 km to the north of H. O is 6 km to the west of H. Combining these two statements we get the final direction diagram as follows-

From the above direction diagram, we check the correctness of the given statements as follows:

Statement I states that branch L is located to the north-west of branch U. This statement is true.

Statement II states branch H is situated exactly in the middle of branch O and branch S. This statement is true.  

Statement III states that branch G is located to the north-east of branch S. This statement is false.

Hence, both Statements I and II are not false.
