PD420 : ? :: RX128 : SY156 :: VL500 : WM528
Show answer & explanation
Correct answer: B
Explanation
PD420 : ? :: RX128 : SY156 :: VL500 : WM528
Just as:
RX128 : SY156
RX → SY
R → S (+1)
X → Y (+1)
128 → 156 (+28)
And:
VL500 : WM528
VL → WM
V → W (+1)
L → M (+1)
500 → 528 (+28)
Similarly:
PD420 : ?
P → Q (+1)
D → E (+1)
420 + 28 = 448
Final Answer: PD420 : QE448
