AD120 : ? :: BK220 : DN720 :: DL170 : FO670
Show answer & explanation
Correct answer: B
Explanation
AD120 : ? :: BK220 : DN720 :: DL170 : FO670
Just as:
BK220 : DN720
B → D (+2)
K → N (+3)
220 + 500 = 720
And:
DL170 : FO670
D → F (+2)
L → O (+3)
170 + 500 = 670
Similarly:
AD120 : ?
A → C (+2)
D → G (+3)
120 + 500 = 620
Correct Answer: B) CG620
