Select the option that is related to the sixth letter-number cluster in the same way as the first letter-number cluster is related to the second letter-number cluster and third letter-number cluster is related to fourth 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)
SP120 : PY180 :: EB200 : BK300 :: ? : KP135
Show answer & explanation
Correct answer: A
Explanation
SP120 : PY180
Letter pattern:
S − 3 = P
P + 9 = Y
EB200 : BK300
E − 3 = B
B + 9 = K
Therefore, for ? : KP:
N − 3 = K
G + 9 = P
So, the letters are NG.
Number pattern:
120 × 3/2 = 180
200 × 3/2 = 300
Therefore:
? × 3/2 = 135
? = 135 × 2/3
? = 90
Hence, the required cluster is: NG90
