Select the option that is related to the second letter-number cluster in the same way as the third letter-number cluster is related to the fourth letter-number cluster and fifth letter-number cluster is related to sixth 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)
? : KM300 :: AI220 : GR395 :: DK310 : JT485
Show answer & explanation
Correct answer: A
Explanation
Just as:
AI220 → GR395
A → G (+6)
I → R (+9)
220 +175 → 395
And:
DK310 → JT485
D → J (+6)
K → T (+9)
310 +175 → 485
Similarly:
? → KM300
We must reverse the process:
K − 6 = E
M − 9 = D
300 − 175 = 125
Correct Option: ED125
