  • Question 1
    1 / -0
    If in a certain code, O is written as E, A as C, M as I, S as O, N as P, E as M, I as A, P as N and C as S, then how will COMPANIES be the written in that code?
    Solution
    As given: O is written as E, A as C, M as I, S as O, N as P, E as M, I as A, P as N and C as S
    Thus, we can write COMPANIES as: 
    C    O    M    P    A    N    I    E    S

    S    E    I    N    C    P    A    M    O
  • Question 2
    1 / -0
    In a certain code, SIKKlM is written as THLJJL. How is TRAINING written in that code?
    Solution
           S       I       K         K          I          M
    −1↓−1↓−1↓ −1↓ −1↓ −1↓-1\downarrow -1\downarrow -1\downarrow -1\downarrow -1\downarrow -1\downarrow
           T       H       L         J         J          L
    Clearly, the letters in the world SIKKIM are moved alternately one step forward and then one step backward to obtain the letters of the code.
    Similarly, TRAINING can be coded as 
           T       R       A         I          N          I           N        G
    −1↓−1↓−1↓ −1↓ −1↓ −1↓ −1↓ −1↓-1\downarrow -1\downarrow -1\downarrow -1\downarrow -1\downarrow -1\downarrow -1\downarrow -1\downarrow
           U       Q       B         H         O          H        O          F
  • Question 3
    1 / -0
    If HERCULES is codes as JCTAWJGQ then what is the code for APHORDITE?
    Solution
    Every alphabet at odd position is increased by 2 and every alphabet at even position is decreased by 2
    H→J\displaystyle H\rightarrow J            A→C\displaystyle A\rightarrow C
    E→C\displaystyle E\rightarrow C            P→N\displaystyle P\rightarrow N
    R→T\displaystyle R\rightarrow T            H→J\displaystyle H\rightarrow J
    C→A\displaystyle C\rightarrow A            O→M\displaystyle O\rightarrow M
    U→W\displaystyle U\rightarrow W            R→T\displaystyle R\rightarrow T
    L→J\displaystyle L\rightarrow J            D→B\displaystyle D\rightarrow B
    E→G\displaystyle E\rightarrow G            I→K\displaystyle I\rightarrow K
    S→Q\displaystyle S\rightarrow Q            T→R\displaystyle T\rightarrow R
                           E→G\displaystyle E\rightarrow G            
  • Question 4
    1 / -0
    In the following question, four numbers/pairs are given out of which three are alike in some manner while one is different. Choose the one which is different from the rest three.
    Solution
    Each of the word follow a pattern where every two consecutive letters differ by +3+3 in alphabetic order.
    But in KNRU, letter N and R differ by +4+4.
    Thus option B is different from others.
    Hence, (B) is the correct answer.
  • Question 5
    1 / -0
    In a coded language SHIFT is written as UFKDV, Then COVET may be written in coded language as -
    Solution
    Given, SHIFT is written as UFKDV. The coding pattern for the same is:
    S +2 → \underrightarrow { +2\quad  }  U
    H −2 → \underrightarrow { -2\quad  }  F
    I +2 → \underrightarrow { +2\quad  }  K
    F −2 → \underrightarrow { -2\quad  }  D
    T +2 → \underrightarrow { +2\quad  }  V
    Similarly, COVET is coded as follows:
    C +2 → \underrightarrow { +2\quad  }  E
    O −2 → \underrightarrow { -2\quad  }  M
    V +2 → \underrightarrow { +2\quad  }  X
    E −2 → \underrightarrow { -2\quad  }  C
    T +2 → \underrightarrow { +2\quad  }  V
    Hence, COVET is coded as EMXCV.
    Therefore, option (A) is the correct answer.
  • Question 6
    1 / -0
    Showing a lady, Suman said, 'She is the daughter of the mother of my father's mother-in-Iaw's only child'. How is the lady related to Suman?
    Solution
    Here, the term my father's mother-in-law's only child means the child of my maternal grandmother.
    Now, the term daughter of the mother means the daughter of my maternal grandmother or my mother herself.
    Therefore, the lady is the mother of Suman.
    Hence, option (B) is the correct answer.
  • Question 7
    1 / -0
    A woman walking with a boy to a market meets another woman and when asked how the boy is related to her, she says, 'My maternal uncle and his maternal uncle's maternal uncle are brothers'. How is the boy related to the woman?
    Solution
    Boy's maternal uncle is the brother of boy's mother. So, boy's maternal uncle's maternal uncle means boy's mother's maternal uncle. Boy's mother's maternal uncle and the woman's maternal uncle are brothers. Hence, the woman is either boy's mother or boy's mother's sister. Thus, the boy is either woman's son or her nephew. Since nephew is not in the given options, we can conclude that the boy is woman's son.
  • Question 8
    1 / -0
    In the following questions one number is wrong in the series Find out the wrong number in each case
    7, 15, 28, 59, 122, 233
    Solution
    Double the number and operate + 1, - 2, + 3, - 4, +5 etc
    Ans (C)
  • Question 9
    1 / -0
    In a certain code language 'CREATIVE' is written as 'BDSBFUJS.' How is 'TRIANGLE' written in that code?
    Solution
    The letters in first half and second half of the word are written in the reverse order and then in the group of letters so obtained the 1st, 3rd ,5th and 7th letters are each move one step forward while the 2nd, 4th, 6th and 8th letters are each moved one step backward to get the code.

  • Question 10
    1 / -0
    Anil introduces Mohan saying, 'He is the husband of the granddaughter of the father of my father'. How is Mohan related to Anil?
    Solution
    The relationship can be analysed as follows:
    (i) Father's father is grandfather.
    (ii) Grandfather's granddaughter is sister.
    (iii) Sister's husband is brother-in-law.
    Hence, Mohan is Anil 's brother-in-law.
