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 : PY530 :: AR1040 : XO810 :: FK840 : ?
Just as
SB760 : PY530
SB → PY
S → P (−3)
B → Y (−3)
760 → 530
760 − 230
And
AR1040 : XO810
AR → XO
A → X (−3)
R → O (−3)
1040 → 810
1040 − 230
Similarly
FK840 : ?
FK → ?
F − 3 = C
K − 3 = H
840 − 230 = 610
Correct answer = CH610
