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)
LW72 : UJ215 :: CA93 : YA278 :: FX103 : ?
Show answer & explanation
Correct answer: B
Explanation
LW72 : UJ215 :: CA93 : YA278 :: FX103 : ?
Just as
LW72 : UJ215
LW → UJ
L(12) → U(21) = +9
W(23) → J(10) = −13
72 → 215
72 × 3−1 = 215
and
CA93 : YA278
CA → YA
C(3) → Y(25) = −4
A(1) → A(1) = 0
93 → 278
93 × 3−1 = 278
Similarly,
F(6) → V(22)
X(24) → D(4)
103 × 3−1 = 308
Final answer: VD308
