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: C
Explanation
1) KLMN50
K=11, L=12, M=13, N=14
Sum = 11 + 12 + 13 + 14 = 50
2) QRST74
Q=17, R=18, S=19, T=20
Sum = 17 + 18 + 19 + 20 = 74
3) CDEF28
C=3, D=4, E=5, F=6
Sum = 3 + 4 + 5 + 6 = 18, but given 28
4) VWXY94
V=22, W=23, X=24, Y=25
Sum = 22 + 23 + 24 + 25 = 94
Only option 3 does not apply to the rule.
Hence, option 3 is different.
