Answers & Solutions:

1) Answer (C)

If ‘P’ denotes’ multiplied by’, ‘T’ denotes ‘subtracted from’, ‘M’ denotes ‘added to and ‘B’ denotes ‘divided by’ then , the correct response of 12 P 6 M 15 T 16 B 4 will be
${12}\times{6}+{15}-{16}\div{4}$=83. option C.

2) Answer (D)

The required ratio is 90:75 = 6:5

3) Answer (B)

If each of the letters in the English alphabet is assigned odd numerical value beginning A = 1, B = 3 and so on, then
H=15
O=29
T=39
E=9
L=23 therefore HOTEL will be equal to 15+29+39+9+23=115

4) Answer (C)

If A=1,B=2 and so on then, each letter will be coded as twice the number assigned to it.
therefore FRANCE will be coded as:12 – 36 – 2 – 28 – 6 – 10. option C.

5) Answer (B)

Consecutive odd numbers are added to the numbers.0 + 3 = 33 + 5 = 88 + 7 = 1515 + 9 = 2424 + 11 = 35Also, the two consecutive letters are pair of opposite letters.=> Ans – (B) : w – 35

6) Answer (B)

If ‘>’ stands for ‘division’, v stands for ‘multiplication’, ‘-‘ stands for ‘greater than’, ‘×’ stands for ‘less than’, ‘<‘ stands for ‘addition’, ‘A’ stands for ‘subtraction’, ‘+’ stands for ‘equal to’, then
option B: 5 v 4 < 2 + 10 v 2 < 2 will be translated as 5$\times4$+2=10$\times2$+2 which is true.
therefore the correct answer is option B.

7) Answer (B)

option A: 8-5 +6 ÷10 =24, not true
option B: 8×5 ×6 ÷10 =24 , true
therefore the correct answer is option B.

8) Answer (B)

Given : MONKO is coded as 57637Thus, I = 1 , J = 2 , K = 3 , L = 4 , M = 5 and so on.Similarly, KLJMN = 34256=> Ans – (B)

9) Answer (B)

The codes of the each alphabet will remain same.Eg = C = 7 , I = 5 , P = 6 , N = 0Thus, PICNIC = 657057=> Ans – (B)

10) Answer (C)

The logic involved in coding of the word ‘WORD’ to ‘ZRUG’ is as represented below
W+3 – Z
O+3 – U
R+3 – R
D+3 – G
Similarly, the code for the word ‘WALLET’ is ‘ZDOOHW’.

11) Answer (B)

While coding a given word, the first letter is replaced by the next letter, the second letter is replaced by the previous letter and so on the pattern is followed.
I -> J
M -> L
A -> B
G -> F
I -> J
N -> M
E-> F
Thus the word IMAGINE is coded as JLBFJMF.

12) Answer (D)

Destroy and Create are opposite to one another.
So, ? should be opposite of Sound which is Silence.
Thus, D is the correct answer.

13) Answer (A)

Here, the first letter is replaced by next alphabet and second is replaced by previous alphabet and the same pattern is followed for the entire word.
ROCKSTAR will be coded as below.
R – >S
O -> N
C->D
K-> J
S-> T
T->S
A->B
R->Q
SNDJTSBQ is the code for ROCKSTAR

14) Answer (C)

For every alphabet at odd place, next alphabet is written, and for every alphabet at an even place, previous alphabet is written. Therefore, ESTABLISHMENT would be written as FRUZCKJRILFMU
Hence, the Option C is the answer

15) Answer (B)

G is 7th letter from the beginning while T is 7th from the end in English alphabets.
Similarly R is 18th from the beginning while I is 18th from the end. The same pattern has been followed for each of the other letters.
The letter at nth position from the beginning is replaced by the letter at the nth position from the end. Thus the code for CHAMPION would be XSZNKRLM.
