Birlasoft Reasoning Questions

DIRECTIONS for the question 1-2: Solve the following question and mark the best possible option.
  1. In a certain code BOARD is written as CNBQE. How is CRIME written in that code?
    1. DSJNF
    2. BQHLD
    3. DQJLF
    4. BSHND
    5. None of these

    Answer: Option C
    B O A R D
    +1 -1 +1 -1 +1
    C N B Q E
    Similarly,
    C R I M E
    +1 -1 +1 -1 +1
    D Q J L F
    Hence option C is the answer.
  2. If the positions of the first and the sixth letters in the word CULTIVATOR are reversed, the positions of the second and the seventh letters are reversed, and so on, which of the following will be the second from the right end after the rearrangement?
    1. T
    2. O
    3. L
    4. V
    5. None of these

    Answer: Option A
    If we will decode the word according to given pattern, we will get the following result
    C U L T I V A T O R => V A T O R C U L T I
    Hence, the second letter from right end in the new arrangement is ‘T’. Hence option A is the answer.
DIRECTIONS for the question 3: Given an input line; the machine arranges the words and numbers in steps in a systematic manner as illustrated afterwards : Study the pattern and answer the question that follows.
Given an input line, a coding machine rearranges the input following certain steps as explained below:
Input: 47 desert go 56 there often 32 12
Step I: there 47 desert go 56 often 32 12
Step II: there 12 47 desert go 56 often 32
Step III: there 12 often 47 desert go 56 32
Step IV: there 12 often 32 47 desert go 56
Step V: there 12 often 32 go 47 desert 56
  1. What will be the fourth step of an input having first step as ‘number game 54 23 always lacking 16 75’?
    1. number 16 lacking 23 game always 54 75
    2. number 16 lacking 23 always 54 game 75
    3. number 16 lacking 23 game 54 always 75
    4. Cannot be determined
    5. None of these

    Answer: Option E
    Step I: number game 54 23 always lacking 16 75
    Step II: number 16 game 54 23 always lacking 75
    Step III: number 16 lacking 23 game 54 always 75
    Since step III is the last step, fourth step can’t be possible
DIRECTIONS for the question 4: The question below contains four statements, followed by four conclusions numbered I, II, III & IV.
You have to take the given statements to be true even if they seem to be at variance with commonly known facts. Read all the conclusions and then decide which of the given conclusions logically follows from the given statements disregarding commonly known facts
  1. Statements:
    1. Some scales are weights.
    2. All weights are metals.
    3. Some metals are rings.
    4. All rings are bands.

    Conclusion:

    1. Some bands are scales.
    2. Some weights are bands.
    3. Some rings are scales.
    4. Some metals are scales.

    None of the conclusions follow

    1. All the conclusions follow
    2. Only I, III and IV follow
    3. Only II and III follow
    4. Only IV follow


    Answer: Option C
    BIG-BUll
    1. Some bands are scales : This is not true as is clear from the above diagram.
    2. Some weights are bands : This is also false as is clear from the above diagram
    3. Some rings are scales : This conclusion also doesn't follow.
    4. Some metals are scales : We are given that 'Some scales are weights' and 'All weights are metals' , therefore, this conclusion follows.

    Hence, the correct answer is option E

DIRECTIONS for the question 5: The question below is followed by two statements marked I and II. Mark as your answer.
  1. if the data in statement I alone are sufficient to answer the question, while the data in statement II alone are not sufficient to answer the question.
  2. if the data in statement II alone are sufficient to answer the question, while the data in statement I atone are not sufficient to answer the question.
  3. if the data either in statement I alone or in statement II alone are sufficient to answer the question.
  4. if the data given in both the statements I and II together are not sufficient to answer the question; and
  5. if the data in both the statements 1 and II together are necessary to answer the question.
  1. How is M related to P?
    1. M's sister is married to R.
    2. R's brother is married to P's sister.

    Answer: Option D
    BIG-BUll
    statement I alone, is not sufficient because it lacks information regarding P. II alone is not sufficient because it lacks information regarding M. Now, from I and II, we get Still, we do not have clear picture and hence the relation can't be determined . So, the correct answer is option D.
DIRECTIONS for the question 6-7: Solve the following question and mark the best possible option.
'P # Q' means 'P is neither greater than nor equal to Q'.
'P © Q' means' P is neither equal to nor smaller than Q'.
'P % Q' means 'P is neither smaller than nor greater than Q’.
'P $ Q' means' P is not smaller than Q'.
'P @ Q' means 'P is not greater than Q'.

Now in each of the following questions, assuming the given statements to be true, find which of the three conclu¬sions I, II and III given below them is/are definitely true and give your answer accordingly.

  1. Statements: K#T,T$B,B@F
    Conclusions:
    1. F$T
    2. K#B
    3. T$F

    1. None is true
    2. Only I is true
    3. Only I and II are true
    4. Only II and III are true
    5. All are true

    Answer: Option A
    Here we have
    K< T…(i)
    T ≥ B….(ii)
    B ≤ F….(iii)
    From (ii) and (iii), we can’t relate F with T. Hence, conclusions I and III do not follow. Similarly, from (i) and (ii), we do not get any specific conclusion regarding B and K. Hence, conclusion II does not follow.
    Thus answer is A option
  2. Statements: R@D, D©W, B$W
    Conclusions:
    1. W#R
    2. B©D
    3. W$R
    1. None is true
    2. Only I is true
    3. OnlyIII is true
    4. Only either I or III is true
    5. All are true

    Answer: Option D
    Here we have
    R ≤ D…(i)
    D > W….(ii)
    B ≥ W….(iii)
    From (i) and (ii), we do not get any specific conclusion regarding R and W. Hence, neither conclusion I (W < R) nor conclusion III (W > R) follows. But these two conclusion make a complementary pair. Hence, either conclusion I or conclusion III follows. From (ii) and (iii), we can’t get any specific conclusion regarding B and D. Hence, conclusion II (B > D) does not follow.
    Now as I and III make a complementry pair i.e. one of them will definitely be true. Hence answer is D option. a;
DIRECTIONS for the question 8-9: Read the information given below and answer the question that follows.
Eight people J, K, L, M, N, O, P and Q are sitting around a circular table, facing the centre, not necessarily in the same order. O is sitting third to the right of M. There is only one person sitting between M and J. There are only three people between J and K. P is an immediate neighbour of J. There are only three people between P and L. N is second to the right of P.
  1. Which of the following is true regarding the given arrangement?
    1. M is an immediate neighbour of K
    2. N is an immediate neighbour of J
    3. P is second to the left of O
    4. There are four people between N and O
    5. None of these

    Answer: Option B
    BIG-BUll
    Hence N is immediate neighbour of J.
  2. Who is sitting second to the left of the one who sitting second to the left of Q?
    1. M
    2. K
    3. N
    4. L
    5. J

    Answer: Option A
    BIG-BUll
    The person sitting 2nd to the left of Q is K and person sitting 2nd to the left of K is M. So, answer is M
DIRECTIONS for the question 10: Solve the following question and mark the best possible option
  1. 'x * y λ z' means 'z is added to the product of x and y'
  2. 'x $ y % z' means 'y is subtracted from x and the resultant is divided by z;.
  3. 'x @ Y © z' means 'x is added to the resultant when y is divided by z'.

In the question below, a set of instruction se¬quences is given. You are required to find out the outcome which should come in place of the question mark (?) in each of the given sets of sequence.

    1. 14 $ 6 * 7 = m
    2. 12 @ m © 4 = ?
    1. 19
    2. 28/3
    3. 28
    4. Can't be determined
    5. None of these

    Answer: Option A
    We have (i) (6x7) - 14 = 28m
    ∴ m = 28
    Now (ii) 12+(28÷4) = 19
    ∴? = 19
    Hence option A
