Odd One Out (SSC CPO 2019 Tier – 1)

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.

Arranging the words in a meaningful order,
REAYBL → BARLEY
ETWAH → WHEAT
EZAMI → MAIZE
SEHCWA → CASHEW

Hence, Wheat, Barley, and Maize are cereals.

But,

Cashew is a dry fruit.

Hence, "SEHCWA" is the odd one.

(31 - 41), (61 - 71) & (83 - 97) are not consecutive prime numbers.

But,

73 and 79 are a pair of continuous prime numbers.

Hence, "(73 - 79)" is the odd one.

Except for Morose, all the other words are synonyms.

Hence, "Morose" is the odd one.

Corresponding letters are coded as the opposite letters.

But,

(OPR - JKL), As, J is not opposite to O and L is not opposite to R.

Hence, "(OPR - JKL)" is the odd one.

Except 178 all other are divisible by 16.

Hence, "178" is the odd one.

Corresponding letters are coded as the opposite letters.

But,

(QJR - JQH), As, R is not opposite to H.

Hence, "(QJR - JQH)" is the odd one.
