Select the option that is related to the third letter-number cluster in the same way as the second letter-number cluster is related to the first letter-number cluster and sixth letter-number cluster is related to fifth 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)
TSR60 : OQS90 :: ZVT80 : ? :: WKU100 : RIV150
Show answer & explanation
Correct answer: A
Explanation
TSR60 : OQS90 :: ZVT80 : ? :: WKU100 : RIV150
Just as:
TSR60 : OQS90
TSR → OQS
R → O = -3
S → Q = −2
T → S = −1
60 → 90 = +30
And:
WKU100 : RIV150
WKU → RIV
U → R = -3
K → I = −2
W → V = −1
100 → 150 = +50
Similarly:
ZVT80 : ?
ZVT :
T → Q (-1)
V → T (−2)
Z → Y (−3)
80 + 40 = 120
Final Answer: QTY120
