Select the option that is related to the fifth letter-number cluster in the same way as the second letter-number cluster is related to the first letter-number cluster and fourth letter-number cluster is related to third letter-number cluster.
(NOTE: Operations should be performed on the whole numbers, without breaking down the numbers 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)
AMR10 : CPM99 :: BKP13 : DNK168 :: RTW25 : ?
Show answer & explanation
Correct answer: B
Explanation
AMR10 : CPM99 :: BKP13 : DNK168 :: RTW25 : ?
Just as:
AMR → CPM
A → C = +2
M → P = +3
R → M = -5
10² − 1 = 100 − 1 = 99
And:
BKP → DNK
B → D = +2
K → N = +3
P → K = -5
13² − 1 = 169 − 1 = 168
Similarly:
RTW25 : ?
R +2 = T
T +3 = W
W -5 = R
25² − 1 = 625 − 1 = 624
