Reasoning Ability

Directions (1-5): Study the following information carefully and answer the questions given below:

There are eight persons A, B, C, D, E, F, G and H who live in an eight-storey building. The ground floor is numbered one and the topmost floor is numbered eight. Each of them is preparing for different competitive exam viz. IAS, SSC, Bank, GATE, PCS, RRB, CAT and NET but not necessarily in the same order.
There is only one floor between the A and the one who is preparing for NET exam. The one who prepares for NET does not live on first floor. D lives just below B. The one who is preparing for IAS exam live on even-numbered floor and just above the floor on which the person who is preparing for PCS exam lives. The one who is preparing for RRB exam lives on an even-numbered floor but not on the 8th floor. Neither D nor H lives on the 1st floor. Only one person lives between the one who is preparing for CAT and D. A lives on an odd-numbered floor and E lives just above A. B lives on the fourth floor. Only two persons live between the one who is preparing for RRB and A. F lives just below the one who is preparing for PCS. D is preparing for neither PCS nor NET. The one who prepares for Bank exam does not live on an odd-numbered floor. G does not prepare for SSC. There are two floors between the H and the one on which E lives. Only two persons live between the one who is preparing for GATE and the one who is preparing for Bank.

Directions (6-10): In each question below is given a group of letters followed by four combinations of digits/symbols numbered (a), (b), (c) and (d). You have to find out which of combinations correctly represents the group of letters based on the following coding system and mark the number of that combination as the answer. If none of the four combinations correctly represents the group of letters, mark (e), i.e. ‘None of these’, as the answer.

Conditions:-

(1) If the first letter is a consonants and the last letter is vowel their codes are to be interchanged.

(2) If the both first and last letters is vowel both are to be coded as 0.

(3) If the both first and last letter is consonants, then their code are to be coded as first letter code.

(4) If the first letter is vowel and last letter is consonants then both are to be coded as the code for the last letter code.

Q6. KUNLEQ

(a) #$87%#

(b) #$57%#

(c) #$87%6

(d) #$8%7

(e) None of these

Q7. IKGFEM

(a) 9#2@%4

(b) 9#2@%9

(c) 4#2@%4

(d) 4#2@84

(e) None of these

Q8. JNLEQU

(a) 187%6#

(b) 18#67%

(c) $876%1

(d) $87%61

(e) None of these 

Q9. EIBQKU

(a) %956#$

(b) %965#$

(c) 0956#0

(d) 059#60

(e) None of these

Q10. BGKEQI

(a) 52#6%9

(b) 52#%69

(c) 92%#65

(d) 92#%65

(e) None of these

Solution(6-10):

S6. Ans.(a)
Sol. Since the first and last both letter are consonants, So both are coded as first letter code i.e. #$87%#

S7. Ans.(c)
Sol. Since first letter is vowel and last letter is consonants, so both are to be coded as last letter code i.e. → 4#2@%4

S8. Ans.(d)
Sol. Since first letter is consonant and last letter is vowel, so their codes are interchanged i.e. $87%61

S9. Ans.(c)
Sol. Since both first and last letter are vowel both are to be coded as 0 i.e. 0956#0

S10. Ans.(d)
Sol. Since first letter is consonant and last letter is vowel, so their code are interchanged i.e. 92#%65

Directions (11-15): In the following questions, the symbols @, ©, %, $ and * are used the following meaning as illustrated below:

‘A © B’ means ‘A is smaller than B’

‘A @ B’ means ‘A is either smaller than or equal to B’

‘A % B’ means ‘A is greater than B’

‘A $ B’ means ‘A is either greater than or equal to B’

‘A * B’ means ‘A is equal to B’

Now in each of these questions assuming the given statements to be true, find which of the two conclusions I and II given below them is/are definitely true? Give answer

(a) If only conclusion I is true

(b) If only conclusion II is true

(c) If either conclusion I or II is true

(d) If neither conclusion I nor II is true

(e) If both conclusion I and II are true

Q11. Statements: P @ R, T $ V, R % S, T @ S

Conclusions: I. R % V II. P % V

Q12. Statements: C $ D, D % E, F @ E, H © C

Conclusions: I. H © F II. H * F

Q13. Statements: M @ N, N © O, O * P, P % R

Conclusions: I. R % M II. P % M

Q14. Statements: T $ U, X @ W, U % X, Y % W

Conclusions: I. T $ X II. Y % U

Q15. Statements: R $ T, S * T, S % U, W @ U

Conclusions: I. U © T  II. W © R
