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)
TK80 : RG160 :: FR60 : DN140 :: ZW40 : ?
Show answer & explanation
Correct answer: A
Explanation
TK80 : RG160 :: FR60 : DN140 :: ZW40 : ?
Just as:
TK80 : RG160
TK → RG
T → R = −2
K → G = −4
80 → 160 = +80
And:
FR60 : DN140
FR → DN
F → D = −2
R → N = −4
60 → 140 = +80
Similarly:
ZW40 : ?
Z → X (−2)
W → S (−4)
40 + 80 = 120
Correct Answer = XS120
