Reasoning Ability Practice Questions for IBPS Clerk – Set 12
Directions (1 – 5): Study the following information carefully and answer the questions given beside.
Eight people – Mukesh, Nandi, Om, Prakash, Qutub, Rajni, Sonu and Teenu are sitting in a straight line with equal distances between each other, but not necessarily in the same order. Some of them are facing north and some are facing south.
Mukesh sits at one of the extreme ends of the row. Only three persons sit between Mukesh and Sonu. Qutub sits exactly between Mukesh and Sonu.
Teenu sits third to the right of Qutub. Nandi is an immediate neighbor of Teenu and faces south. Om sits second to right of Rajni. Om is not an immediate neighbour of Sonu.
Immediate neighbours of Sonu face opposite directon (i.e. if one neighbor faces north then the other neighbour faces south and vice-versa.) Immediate neighbours of Rajni face opposite directions.
Mukesh and Prakash face the same direction as Qutub. Both the immediate neighbours of Qutub face south.

Solutions:
(1 – 5):
1. B)   2. A)   3. C)   4. B)   5. A)  
6. C) From S1: Some girls are smart. Converse of it will be - Some smarts are girls. 
Now, if some smarts are girls, what are the other smarts? They may be girls as well or they may not be girls. 
If they are also girls, 'All smarts are girls' would be true and if they are not girls, 'Some smarts are not girls' would be true. It means either the former or the latter conclusion follows. Clearly, either C1 or C3 follows. 
From S2: Similarly, 'Some girls may not be books' is also a possibility. Hence, C2 follows as well.
From S1 and S2: As the middle term 'girls' is not distributed even once, we can't deduce a definite relationship between the classes of 'Smart' and 'books'. C4 doesn't follow.
7. E) From S2 and S1: Some banks are mobiles + All banks are wallets = I + A = Some mobiles are wallets. Using this conclusion we can deduce that 'All mobiles being wallets is a possibility' and the converse of 'Some mobiles are wallets' will also give us - Some wallets are mobiles. Hence, both C1 and C2 follow and if C2 definitely follows, C3 doesn't follow. 
From S2: Converse of 'Some banks are mobiles' - Some mobiles are banks. Hence, C4 follows as well. Clearly, conclusions I, II and IV follow.
8. C) From S2: Converse of 'All nurses are patients' - Some patients are nurses. Hence C1 follows. 
From S1: We are not sure of the elements of the class 'nurses' here. Clearly, 'Some nurses may be patients'. Hence, C2 follows as well.
From S1: From the same statement, we can observe that if some doctors are not nurses, what are the rest of the doctors? They may be nurses or they may not be nurses. Clearly, 'Some doctors may be nurses' is true.
From S2: Converse of 'All nurses are patients' - Some patients are nurses. Clearly, C4 doesn't follow. 
Hence, out of 4 given conclusions, only C4 doesn't follow.
9. B) From 1: C1 is invalid as of the statements, none mentions 'Urban people' or 'literate people. C1, hence, doesn't follow.
From 2: Some villagers are rustic + All rustic people are illiterate = I + A = Some villagers are illiterate. So, if some villagers are illiterate, what are the rest of the ones, what are they? They could be illiterate too or they could not be illiterate. 
Following the logic, we can deduce that it's possible that some villagers are not illiterate. C2, hence, follows.
From S1: Converse of 'Some villagers are rustic' - Some rustic people are villagers. Following the same logic, we can say that 'All rustic people can be villagers'. C3 follows too.
Now, we have already derived the conclusion between S1 and S2 - Some villagers are illiterate. So, the given conclusion 'No illiterate person is a villager' doesn't follow. 
Clearly, C1 and C4 don't follow among all.
10. A) From S2 and S1: Converse of S2 - Some serious people are fit for the job + Concerse of S1 - No fit for the job people are you = I + E = Some serious people are not you. Hence, C4 follows but C2 doesn't. 
From S2: Converse of S2 - Some people who are fit for the job are serious = Some serious people are fit for the job. Clearly, C1 doesn't follow.
From S1: None of you is fit for the job. Even if we consider its converse, we won't be getting any possibility between 'You' and 'fit for the job people'. C3, hence, doesn't follow.
Clearly, C1, C2 and C3 are not following.
11. B) Combining the equations to find the relationship between D and Z, we get
D = F = R ≤ K = B ≤ A < Z
Clearly, the common sign of inequalities between D and Z is of '<'. Conclusion D < Z is hence stays true. C1, hence, follows.
Similarly, combining equations to find the relationship between X and S, we get
X < Y ≤ T < B = K ≥ R = F = D > S
Clearly, the signs are getting reversed and hence we can't define a relationship between X and S. C2, hence, doesn't follow.
12. C) Combining equations to find the relationship between T and L, we get
T ≤ S = P = Q ≤ D ≤ E = R = L
Here, the common sign of inequalities between T and S is of '≤' and the given conclusion is T < L. C1, hence, doesn't follow.
Similarly, combining equations to find the relationship between K and P, we get
K > L = R = E ≥ D ≥ Q = P
Here, the common sign between K and P is of '>' and the conclusion is K > P. C2, hence, follows.
13. E) Combining equations to find the relationship between R and 5, we get
R = 0 > 6 ≥ 3 > 8 > 9 ≠ 5 = 4
Clearly, we can't find a definite relationship between R and 5.
Same goes with in case of 0 and 4. But when observe we find that
R = 0 and 4 = 5
Therefore, in any scenario, R or 0 must be either greater than, equal to or less than 4 or 5.
Clearly, either C1 or C2 follows.
14. C) Combining both the equations to find the relationship between O and Y, we get
O ≤ G = E ≤ P < Q ≤ K ≤ T < Y
Clearly, the common sign of inequalities between O and Y is of '<' and the given conclusion is O < Y. C1, hence, follows.
Similarly, for K and G, we get
K ≥ Q > P ≥ E = G
Clearly, the common sign between K and G is of '>' and the given conclusion is K > G. C2, hence, follows as well.
15. B) Combining equations to find the relationship between 2 and 7, we get
2 > 3 > 4 > 8 = 7
Clearly, the common sign of inequalities between 2 and 7 is of '>' and the conclusion given is 2 > 7. C1, hence, follows.
Similarly, for 9 and 3 we get,
9 ≤ 7 = 8 < 4 < 3
Here, the common sign of inequalities is of '<' whereas the conclusion given is 9 ≤ 3. C2, hence, doesn't follow.
