Answers & Solutions:
1) Answer (B)
“BLADE” $\rightarrow$ “LBAED” the position of “A” remains the same where as “B” and “L” interchange their positions and “D” and “E” interchange their positions. Similarly “TABLE”$\rightarrow$
keep “B” as it is, interchange “T” and “A” and “L” and “E” which would form “ATBEL”. Hence OPTION B is the answer
2) Answer (B)
$\left[B\right] \rightarrow \left[W\right]\left(difference -5 \right)$
$\left[R\right] \rightarrow \left[M\right]\left(difference -5 \right)$
$\left[I\right] \rightarrow \left[D\right]\left(difference -5 \right)$
$\left[C\right] \rightarrow \left[X\right]\left(difference -5 \right)$
$\left[K\right] \rightarrow \left[F\right]\left(difference -5 \right)$
similarly “GOLDS” $ \rightarrow$ “BJGYN”
3) Answer (C)
number corresponding to the letter of the alphabet
$\left[S\right] \rightarrow \left(19 \right)$
$\left[H\right] \rightarrow \left(8 \right)$
$\left[O\right] \rightarrow \left(15 \right)$
$\left[E\right] \rightarrow \left(5 \right)$
$\left[S\right] \rightarrow \left(19 \right)$
“SHOES” $ \rightarrow $”19815519″
similarly
$\left[S\right] \rightarrow \left(19 \right)$
$\left[E\right] \rightarrow \left(5 \right)$
$\left[E\right] \rightarrow \left(5 \right)$
$\left[D\right] \rightarrow \left(4 \right)$
“SEED” $ \rightarrow $”19554″
similarly “CHAIR” $ \rightarrow $ “381918”
4) Answer (C)
In the given code, A = 1, B = 2,…Z = 26.
RAM is coded as R + A + M – 1. i.e. 18 + 1 + 13 – 1 = 31
FAN is coded as F + A + N – 1. i.e. 6 + 1 + 14 – 1 = 20
COR: C + O + R -1 = 3 + 15 + 18 -1 = 35
Therefore, Option C is correct.
5) Answer (C)
The given code follows the addition of corresponding numbers of the alphabets. i.e.
In COW ; C =3; O = 15;W= 23.
so, 3+ 15+ 23 =41
Similarly, PIG ; P= 16;I=9;G=7
so, 16+9+7 = 32
Similarly, CUP will be coded as C=3; U=21;P=16;
CUP = 40.
6) Answer (D)
The given code follows the replacement of its previous digits at a gap of three alphabets from right to left. i.e. R is replaced by N ; O is replaced by K. and so on.
Hence, code for CURTAIN is JWPNQY
7) Answer (A)
The given word is replaced by addition of a consecutive terms i.e. S is replaced by T then T is replaced by V(addition of 2) and so on.
Hence, COWARD will be replaced by DOZEWJ
8) Answer (A)
R corresponds to 8 , O corresponds to 2 ,C corresponds to 6 , K corresponds to 4 , S corresponds to 9
similarly M-0, E -1, N-5, T-7, R-8
now
T-7
R-8
O-2
M-0
N-5
9) Answer (D)
‘MOTHER’
divide it into 2 parts “MOT” and “HER”
now write each of the parts in Reverse order
“MOT” becomes “TOM”
“HER” becomes “REH”
combine the 2 parts we get “TOMREH”
following the above pattern
‘STORME’
divide it into two parts “STO” and “RME”
now reverse each of the parts
we get “OTS” and “EMR”
combine them we get “OTSEMR”
10) Answer (C)
The letters of alphabet is written corresponding to the number{A-1,B-2,C-3,D-4,E-5,F-6 ……………………… X-24,Y-25.Z-26}
‘DRAUGH’ is written as ‘LKYEVH’
now add 4 to each numerical value of each letter
D(4) + 4 = 8 (H) { we know H is 8}
R(18) + 4 = 22(V)
A(1) + 4 = 5 (E)
U(21) +4 = 25 (Y)
G(7) + 4 = 11 (K)
H(8) + 4 = 12 (L)
we obtained “HVEYKL” now reverse this to get the answer “LKYEVH”
following the same pattern
MAHTOS
adding 4 to each letter
M(13) + 4 = 17(Q)
A(1) + 4 = 5(E)
H(8) + 4 = 12(L)
T(20) + 4 = 24(X)
O(15) + 4 = 19(S)
S(19) + 4 = 23(W)
we get “QELXSW” now reverse it we get
WSXLEQ
11) Answer (C)
In a certain code language, ‘JAN’ is written as ‘25’, ‘WED’ is written as ‘32’. What is the code for ‘SEP’ in that code language?
Put numbers corresponding to the letters of alphabet ( A-1,B-2 , C-3 ……………… X-24,Y-25,Z-26)
now J-10, A-1, N-14
adding 10+1+14 = 25
similarly W-23, E-5, D-4 adding 23+5+4 = 32
now
S-19, E-5, P-16
adding 19+5+16 = 40
12) Answer (A)
letters of the alphabet corresponding to the number ( A – 1, B -2 , C -3 , D -4 …………… X- 24, Y-25 , Z- 26)
difference between letters between (R ,L) is -6 similarly
difference between letters between (A, U) ,(P,J) , (I,C) and (D, X) is -6
{ if we get answer in negative integer add 26 to it to get the letter for example A= 1 – 6 = -5
-5+26 = 21 (U)}
following the pattern
13) Answer (C)
As per english alphabets,for LIP, L=12; I=9; P=16, to the sum of these values add 3.
i.e., 12+9+16 = 37
37 + 3 = 40.
for GILT, G = 7; I = 9; L = 12; T = 20
7+9+12+20 = 48
48 + 3 = 51
In the same way for ROPE, R = 18; O = 15; P=16; E=5.
18+15+16+5 = 54
54 + 3 = 57.
Therefore the answer is 57.
14) Answer (C)
Pattern followed,
Using this pattern, CREATE can be written as RCAEET
15) Answer (B)
