  • Question 1/10
    1 / -0.25
    If 2 * 3 * 7= 2349 & 1 * 3 * 5= 1325 then find 3 * 7 * 4= ?
    Solutions
    2 * 3 * 7 is operated as 1st two no. are written as it is, but 3rd or last no. is squared
    23 and square of 7 makes 2349
    1 * 3 * 5 = 1325
    3 * 7 * 4 = 3716
    Hence, option C is the correct answer.
  • Question 2/10
    1 / -0.25
    If in some language BOLLYWOOD is coded as “263375664” and HOLYWOOD is coded as “86375664”, then what is the code for TOLLYWOD?
    Solutions

    Considering the place value of letters we get,
    As,
    B(2),O(15),L(12),L(12),Y(25),W(23),O(15),O(15),D(4)
    ⇒ B(2),O(1+5),L(1+2),L(1+2),Y(2+5),W(2+3),O(1+5),O(1+5),D(4)
    ⇒263375664
    and
    H(8),O(15), L(12),Y(25),W(23),O(15),O(15),D(4)
    ⇒ H(8),O(1+5), L(1+2),Y(2+5),W(2+3),O(1+5),O(1+5),D(4)
    ⇒ 86375664
    Similarly, TOLLYWOD is coded as
    T(20),O(15),L(12),L(12),Y(25),W(23),O(15), D(4)
    ⇒ T(2+0),O(1+5),L(1+2),L(1+2),Y(2+5),W(2+3),O(1+5), D(4)
    ⇒ 26337564
    Hence, option D is the correct answer.
  • Question 3/10
    1 / -0.25
    In a certain code language, "MWS" is written as "ACBCAI". How is "PYX" written in that code language?
    Solutions

    Here, the pattern is:

    MWS → 132319 (M = 13, W = 23, S = 19)

    Now, take the obtained numbers and write the respective letters as per English Alphabetical order.

    132319 → ACBCAI (A = 1, B = 2, C = 3, I = 9)

    So, MWS → 132319 → ACBCAI

    Thus, MWS is coded as ACBCAI.

    Similarly,

    PYX → 162524 (P = 16, Y = 25, X = 24)

    162524 → AFBEBD (A = 1, B = 2, D = 4, E = 5, F = 6)

    So, PYX → 162524 → AFBEBD

    Thus , PYX is codded as AFBEBD.

    Hence, option B is the correct answer.

  • Question 4/10
    1 / -0.25
    If EFMIJ means DELHI, then find the last letter of IQBOS after decoding –
    Solutions
    E (-1) = D
    F (-1) = E
    M (-1) = L
    I (-1) = H
    J (-1) = I
    Similarly,
    I (-1) = H
    Q (-1) = P
    B (-1) = A
    O (-1) = N
    S (-1) = R 

    Thus, R is the last letter.
    Hence, option B is the correct answer.

  • Question 5/10
    1 / -0.25
    In a code language, ‘ACCOMMODATINGLY’ is written as ‘DDBNNPBEPOJUZMH’. How will ‘ACCESSIBILITIES’ be written as in that language?
    Solutions

    Hence, option B is the correct answer.

  • Question 6/10
    1 / -0.25
    If COMMENT is coded as 4171617102027 and SHARE is coded as 201042210, then how will LIKE be coded as?
    Solutions

    As,

    COMMENT= C(3)O(15)M(13)M(13)E(5)N(14)T(20)

    = C(3+1)O(15+2)M(13+3)M(13+4)E(5+5)N(14+6)T(20+7)

    = C(4)O(17)M(16)M(17)E(10)N(20)T(27)

    =4171617102027

    And

    SHARE= S(19)H(8)A(1)R(18)E(5)

    = S(19+1)H(8+2)A(1+3)R(18+4)E(5+5)

    = S(20)H(10)A(4)R(22)E(10)

    =201042210

    Similarly,

    LIKE= L(12)I(9)K(11)E(5)= L(12+1)I(9+2)K(11+3)E(5+4)

    =L(13)I(11)K(14)E(9)

    =1311149

    Hence, option A is the correct answer.

  • Question 7/10
    1 / -0.25
    If each of the letters of the English alphabet is assigned an odd numerical value beginning with A = 1, B=3 and so on, what will be the total value of the letters of the word RADICAL?
    Solutions

    The pattern is:

    R = 35

    A = 1

    D = 7

    I = 17

    C = 5

    A = 1

    L = 23

    R + A + D + I + C + A + L

    35 + 1 + 7 + 17 + 5 + 1 + 23 = 89

    Hence, option C is the correct answer.

  • Question 8/10
    1 / -0.25
    In a certain code language,
    '134' means nice and tasty
    '478' means 'look nice pictures' and
    '729' means 'pictures are colourful'.
    Which of the following digits stands for look
    Solutions
    In the first and second statements, the common code digit is 4 and the common word is nice. Thus, 4 stands for nice. In the second and third statements, the common code digit is '7' and the common word is 'pictures'. Thus, '7' means 'pictures'. Thus, in the second statements, '8' means 'look'.
  • Question 9/10
    1 / -0.25
    In a code language, VIBRANT is written as CJWSUOB. Then, how ELASTIC will be coded as?
    Solutions

    Hence, option A is the correct answer.

  • Question 10/10
    1 / -0.25
    In a Code language CAT is written as BDZBSU, How will LION be written in that Language.
    Solutions

    Here we can see that each alphabet is replaced with its former and latter alphabet. “c” is coded as “BD” , ‘A’ Is coded as ‘ZB’ and so on.


    Therefore, ‘LION’ will be coded as ‘KMHJNPMO’.


    Hence, option C is the correct answer.
