The common word in the first two statements is ‘old’ = 5

And the common word in the first and last statements is ‘books’ = 3

Now, the only word left in 1st statement is “are” = 2

=> Ans – (B)

The common word in the first two statements is ‘is’ = 4

And the common word in the first and last statements is ‘blue’ = 8

=> Ans – (A)

The pattern followed is that in each word, the first letter is replaced by the next alphabet in the English alphabetical series, and rest of the letters are written as it is.

Eg :  L (+1 letter) = M and UTE = UTE, thus LUTE <=> MUTE

and G (+1 letter) = H and ATE = ATE, thus GATE <=> HATE

Similarly, B (+1 letter) = C and LUE = LUE, thus BLUE <=> CLUE

=> Ans – (A)

APPLE stands for ETTPI

The pattern followed is :

Similarly, for DELHI :

=> Ans – (A)

Given : CUSTOM is written as UCTSMO

The pattern is that in groups of 2 letters (from either side), both letters are swapped.

Eg = CU : UC , ST : TS , OM : MO

Similarly, for PA RE NT : AP ER TN

Thus, PARENT is written as APERTN

=> Ans – (D)

Given : FRACTION is written as FNAITCOR

The pattern followed is that the letters are odd positions (from left side) are in the same position but letters in even position are written in reversed order.

Letters at odd position = FATO : FATO

Letters at even position = RCIN : NICR

Similarly, for QUANTITATIVE,

Letters at odd position = QATTTV : QATTTV

Letters at even position = UNIAIE : EIAINU

Thus, final answer after merging letters at both position : QEAITATITNVU

=> Ans – (D)

Expression : 8 × 6 +2 =22

(A) : +,× , 2 and 6

$\equiv8+2\times6=22$

L.H.S. = $8+12=20\neq$ R.H.S.

(B) : +, ×, 2 and 8

$\equiv2+6\times8=22$

L.H.S. = $2+48=50\neq$ R.H.S.

(C) : +, ×, 6 and 8

$\equiv6+8\times2=22$

L.H.S. = $6+16=22=$ R.H.S.

=> Ans – (C)

(A) : 50 × 5 ÷ 2 – 30 + 25 = 25

$\equiv50\div5\times2+30-25=25$

L.H.S. = $10\times2+5$

= $20+5=25=$ R.H.S.

=> Ans – (A)

The pattern followed is that all the numbers are added and twice of the middle number is subtracted from the sum to obtain final result.

Eg : 2 × 4 × 6 = $(2+4+6)-(2\times4)=12-8=4$

and 9 × 3 × 7 = $(9+3+7)-(2\times3)=19-6=13$

and 4 × 7 × 6 = $(4+7+6)-(2\times7)=17-14=3$

Similarly, 9 × 7 × 8 = $(9+7+8)-(2\times7)=24-14=10$

=> Ans – (A)

The product of the first two numbers is added to the sum of last two numbers.

Eg : $(3\times5)+(7+2)=15+9=24$

and $(2\times4)+(6+8)=8+14=22$

Similarly, $(4\times4)+(8+9)=16+17=33$

=> Ans – (A)

TRIPPLE is written as SQHOOKD

The pattern followed is :

Similarly, for DISPOSE :

=> Ans – (A)

Given : TRANSFER is coded as RTNAFSRE

The pattern is that in groups of 2 letters (from either side), both letters are swapped.

Eg = TR : RT , AN : NA , SF : FS , ER : RE

Similarly, for EL EP HA NT : LE PE AH TN

Thus, ELEPHANT is written as LEPEAHTN

=> Ans – (B)

Given : MONKO is coded as 57637

Thus, I = 1 , J = 2 , K = 3 , L = 4 , M = 5 and so on.

Similarly, KLJMN = 34256

=> Ans – (B)

The number is the sum of the place values of the alphabets.

H = 8

HAT = 8 + 1 + 20 = 29

=> BOX = 2 + 15 + 24 = 41

=> Ans – (D)

(D) : $64\times8-9-8=64$
L.H.S. = $512-17=495\neq$ R.H.S.
