Select the option that is related to the fourth letter-number cluster in the same way as the first letter-number cluster is related to the second 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)
QV105 : RS385 :: ? : IT700 :: BT505 : CQ785
Show answer & explanation
Correct answer: A
Explanation
QV105 : RS385 :: ? : IT700 :: BT505 : CQ785
Just as:
QV105 : RS385
Q → R (+1)
V → S (-3)
385 − 280 = 105
And:
BT505 → CQ785
B → C (+1)
T → Q (-3)
785 − 280 = 505
Similarly:
? : IT700
I (9) − 1 = H
T (20) + 3 = W
? + 280 = 700
? = 700 − 280 = 420
