In the following question, select the odd letter-number cluster from the given alternatives.
(NOTE: Operations should be performed on the whole numbers, without breaking down the number into its constituent digits. E.g.13 – Operations on 13 such as adding/subtracting/multiplying etc. to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed)
Show answer & explanation
Correct answer: D
Explanation
1) GIKM40
G(7) + I(9) + K(11) + M(13)
= 7 + 9 + 11 + 13
= 40
2) PRTV76
P(16) + R(18) + T(20) + V(22)
= 16 + 18 + 20 + 22
= 76
3) TVXZ92
T(20) + V(22) + X(24) + Z(26)
= 20 + 22 + 24 + 26
= 92
4) OQSU82
O(15) + Q(17) + S(19) + U(21)
= 15 + 17 + 19 + 21
72 ≠ 82
But the option gives 82.
Therefore, the odd group is OQSU82
