     PROCESSOR is coded as D4F3C5C1E1S1S1E3C6

     a. QUADRANT

  • Q1C7A1B2F6A1B7E4

  • W1E4B7B2E3W1

  • W1C3B7B2C3W1
  • W1C3G7B2E3W1

 

Answer & Explanations

 

1. Exp:  Word:  M      U       S       E       U        M

          Logic: -1      -2      -3      -4       -5       -6

          Code:   L      S        P       A        P        G

 

   Similarly, the code for PALACE is

         Word:  P       A        L       A       C        E

         Logic: -1      -2       -3       -4       -5      -6

         Code:  O       Y        I        W       X       Y

2. Exp: The alphabets are coded as follows:

 

        D   E   L   H   I    C   A   U   T

        7    3   5    4   1    8    2    9    6

 

  So, in CALICUT, C is coded as 8, A as 2, L as 5, U as 9 and T as 6. Thus, the code for  CALICUT is 
  8251896.

3. Exp: The code for the word DANCE is 21211.

4. Exp: Number of letters in the word CONTRACT = 8 and 8 x 7 = 56.

          Number of letters in the word GROWTH = 6 and 6 x 5 = 30.

         Similarly, DISTRIBUTION => 12 and 12 x 11 = 132.

5. Exp: In this product of the digits in the place-values of the letters as per the alphabet is obtained
   first and then added i.e, BLOCK

   => B = 2

        L = 12 => 1 x 2 = 2

        O = 15 => 1 x 5 = 5

        C = 3

        K = 11 => 1 x 1 = 1

        Now (2 + 2 + 5 + 3 + 1) = 13.

       So, BLOCK = 13.

      Similarly, SCIENCE = 38.

6. Exp: In this coding, the letters from either end of the word are written, first a letter from the right
   end and then a letter from the left end of the word and so on. Hence DISTANCE is coded as
   EDCINSAT.

   Similarly, ACQUIRE is coded as EARCIQU.

7. Exp: It is given that 28 + 14 = 50 => (2 + 8) x (1 + 4)

    => 10 x 5 = 50 and 36 + 43 = 63 => (3 + 6) x (4 + 3)

    => 9 x 7 = 63 then  44 + 52 => (4 + 4) x (5 + 2) => 8 x 7 = 56.

8. Exp: 14 x 15 = 14 + 15 = 29 and 29 – 4 = 25.

           26 x 42 = 26 + 42 = 68 and 68 – 4 = 64.

           Similarly, 73 x 31 = (73 + 31) – 4 = 104 – 4 = 100.

9. Exp: In the first and second statements, the common code word is ‘kew’ and the common word is
           ‘she’. So, ‘kew’stands for ‘she’.        

         In the first and third statements, the common code word is ‘deko’ and the common word is
         ‘apples’. So, ‘deko’stands for ‘apples’.

10. a. Exp: PROCESSOR =>

            P = 16 and D4 => 4 x 4 = 16 = P

            R = 18 and F3 => 6 x 3 = 18 = R

            O = 15 and C5 => 3 x 5 = 15 = O and so on.

          Hence, PROFESSOR is coded as D4F3C5C1E1S1S1E3C6.

          QUADRANT is coded as Q1C7A1B2F3A1B7E4.

    b. Exp: WINDOW is coded as W1C3B7B2E3W1.
