Question

ER 32 is related to DS 34 in a certain way. In the same way, XW 54 is related to WX 56. To which of the given options is ZB 78 related, following the same logic?

• A. YC 80
• B. YA 78
• C. YA 80
• D. YA 79

Answer 1

Answer:

A. YC 80

Look at the pattern:

ER 32 → DS 34

• E → D (−1)

• R → S (+1)

• 32 → 34 (+2)

XW 54 → WX 56

• X → W (−1)

• W → X (+1)

• 54 → 56 (+2)

So the rule is:

• First letter −1

• Second letter +1

• Number +2

Now apply to ZB 78:

• Z → Y (−1)

• B → C (+1)

• 78 → 80 (+2)

Answer: YC 80
