Letter Series Involving Triplets

The English alphabet contains 26 letters, as shown : A,B,C,D,E,F,G,H,I,J,K,L,M,N,O,P,Q,R,S,T,U,V,W,X,Y,Z.

We should know the code of every alphabet as mentioned before. Letter series includes group of letters and we need to find the relation between the letters. 

Triplets are the groups of letters which include only 3 letters in a group whether its vowel or consonant. For example ABC, DEF............ So, ABC is a Triplet which includes 3 letters. 

Illustration 1 : Find the next triplet.

ABC, EFG, IJK, ?

(a) LMN   (b) MNO   (c)  NOP   (d) PQR

Answer : (b)

Explanation :  In the above series ,we need to find the relation between the letters in a triplet. A is 1, B is 2, c is 3. So, there is difference of 1 in the letters of a triplet. But last letter of first triplet is C(3) and first letter of second triplet is E(5) ,  The difference is 2.

Now, it is clear that the difference between the letters of a triplet is 1 and the difference between the last letter of the triplet and first letter of next triplet is 2.  A(1) , B(2) , C(3)

E(5) , F(6) , G(7)

I(9) , J (10) , K(11)

M(13), N(14) O(15)

So, the answer is MNO.

Illustration 2 :  Find the next triplet.

BDF, HJL, NPR,  ?

(a) UVW    (b) VWX   (c)  TVX  (d)  XYZ

Answer : (c)

Explanation : In the above series ,we need to find the relation between the letters in a triplet. B is 2, D is 4, F is 6. So, there is difference of 2 in the letters of a triplet. But last letter of first triplet is F(6) and first letter of second triplet is H(8) ,  The difference is 2. Now, it is clear that the difference between the letters of a triplet is 2 and the difference between the last letter of the triplet and first letter of next triplet is  also 2.

B (2)  D (4)   F(6)   ,

H (8)    J(10)   L(12)

N (14)    P(16)   R(18), 

T  (20)   V (22)   X (24)

So, the answer is TVX.

Illustration 3 :  Find the next triplet.

AZZ , CXW, EVT , ?

(a) UVW  (b) VWX   (c) GTQ   (d) None of these

Answer : (c)

Explanation :  In the above series ,we need to find the relation between the letters in a triplet. A is 1, Z is 26,  Z is 26. So, there is no exact relation between the letter of the triplet. So , the relation between the first letter of first and second triplet is difference of 2 . Similarly, the relation between the second letter of first and second triplet is difference of 2 but in descending order. And also the  the relation between the third letter of first and second triplet is difference of The difference is 3 but in descending order. 

A (1)    Z (26)    Z (26)

C (3)   X (24)    W(23)

E (5)   V (22)    T (20)

G (7)   T (20)    Q (17)

So, the answer is GTQ.
