10. These questions are based on a certain code language. Understand the logic in the coding and

PROCESSOR is coded as D4F3C5C1E1S1S1E3C6

• Q1C7A1B2F6A1B7E4
• Q1D6A1B2F3A1B7E4
• Q1C7A1B2F3A1B7E4
• Q1C7A1D2C6A1B7E5

b. WINDOW

• W1E4B7B2E3W1
• W1C3B7B2E3W1
• W1C3B7B2C3W1
• W1C3G7B2E3W1

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.
