Odd One Out (SSC CPO 2019 Tier – 1)

11. Choose the odd one. [S.S.C CPO 12/12/2019 (Morning)]

(a) DGK
(b) MLY
(c) ENR
(d) QFW

Correct Answer: (c) ENR

Solution:The pattern followed here is :

Sum of alphabetical positions of 1^st and 2^nd letter = 3^rd letter

DGK → D(4) + G(7) = K(11)

MLY → M(13) + L(12) = Y(25)

QFW → Q(4) + F(6) = W(23)

But,

ENR → E(5) + N(14) = S(19) ≠ R(18)

Hence, "ENR" is the odd one.

12. Rearrange the given letters to form meaningful words and select the option which is different from the other three words. [SSC CPO 12/12/2019 (Evening)]

(a) REAYBL

Solution:Arranging the words in a meaningful order,
