T=20, R=18, A=1, N=14, Q=17,U=21, I=9, L=12 => 20181141720912
Similarly: P=16, E=5, R=18, P=16, L=12, E=5, X=24 => 165181612524
A=1        B=2        C=3        D=4        E=5         F=6         G=7        H=8        I=9          J=10       K=11      L=12       M=13

The series follow the rule of +1, -2, +1, -2, +1, -2,… V+1=W, I-2=G, S+1=T, I-2=G, O+1=P, N-2=L =>WGTGPL

Similarly, M+1=N, I-2=G, S+1=T, S-2=Q, I+1=J, O-2=M, N+1=O =>NGTQJMO

A=1        B=2        C=3        D=4        E=5         F=6         G=7        H=8        I=9          J=10       K=11      L=12       M=13 N=14     O=15     P=16      Q=17     R=18      S=19      T=20      U=21     V=22      W=23    X=24      Y=25      Z=26

The series follow the rule of +1,-2,+3,-4,+5,-6,… T+1=U, R-2=P, O+3=R, P-4=L, H+5=M, Y-6=S =>UPRLMS

W+1=X, A-2=Y, L+3=O, K-4=G => XYOG

Similarly, C+1=D, R-2=P, E+3=H, A-4=W, T+5=Y, E-6=Y =>DPHWYY

A=1        B=2        C=3        D=4        E=5         F=6          G=7        H=8        I=9          J=10       K=11      L=12       M=13 N=14     O=15     P=16      Q=17     R=18      S=19      T=20      U=21     V=22      W=23    X=24      Y=25      Z=26

Add the numeric equivalent alphabets and then reverse the result. S=19, M=13, A=1, L=12 =>19+13+1+12+12=57 =>75 (Swapping the places of unit 7 10's place digit ).

C=3, L=12, A=1, Y=25 =>3+12+1+25=41

=>14 (Swapping the places of unit 7 10's place digit ).

Similarly, C=3, R=18, I=9, M=13, E=5 => 3+18+9+13+5 = 48

=>84 (Swapping the places of unit 7 10's place digit ).

A=1        B=2        C=3        D=4        E=5         F=6         G=7        H=8        I=9          J=10       K=11      L=12    M=13 N=14     O=15     P=16      Q=17     R=18      S=19      T=20      U=21     V=22      W=23    X=24      Y=25      Z=26

12*9=108 =>1+0+8=9 ,

15*7=105 =>1+0+5=6,

17*8=136 =>1+3+6=10,

16*9=144 => 1+4+4=9

8*9=72 => 72 + (8+9) = 89,

11*12= 132 + (11+12) = 155,

4*6=24= 24 + (4+6) = 34.

Solution: Given, SUBSTITUTION is written as ITSBUSNIOTUT. First, the first six letters and then the last six letters are written in reverse order to obtain the code.

Option(B) Explanation J + 2 = L O + 2 = Q C + 2 = E K + 2 = M Y + 2 = A Therefore, the code for CRAZY is C + 2 = E R + 2 = T A + 2 = C Z + 2 = B Y + 2 = A

 

A*B=40 : 5*8=40

=> A=5, B=8 B*C=96 : 8*12=92

=> B=8, C=12 A*C=60 : 5*12=60

=> A=5, C=12 D*C=108 : D*12=108

=>D=9
