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)
SB760 : PY530 :: AR1040 : XO810 :: FK840 : ?
Show answer & explanation
Correct answer: C
Explanation
SB760 : PV530 :: AR1040 : XO810 :: FK840 : ?
Just as
SB760 : PV530
SB → PV
S(19) → P(16) = −3
B(2) → V(22) = −6
760 → 530
760−230=530
And
AR1040 : XO810
AR → XO
A(1) → X(24) = −3
R(18) → O(15) = −3
1040 → 810
1040−230=810
Similarly
FK840 : ?
F(6) − 3 = C
K(11) − 3 = H
840−230=610
Number = 610
Correct answer: CH610
