SK -1 is related to OO in a certain way. In the same way IA 2 is related to EE 6. To which of the following is EO 5 related, following the same logic ?

AAS 9

BAS 1

CAS -1

DAT 9

Answer:

A. AS 9

Read Explanation:

Observe carefully:

1. SK −1 → OO

  • S (19) → O (15) ⇒ −4

  • K (11) → O (15) ⇒ +4

2. IA 2 → EE 6

  • I (9) → E (5) ⇒ −4

  • A (1) → E (5) ⇒ +4

So the letter rule is consistent:

  • First letter → −4

  • Second letter → +4

    Apply to EO 5:

  • E (5) → 5 − 4 = 1 → A

  • O (15) → 15 + 4 = 19 → S

So letters → AS

Now the number pattern:

Check:

  • −1 → (−1) + 0? → no visible number

  • 2 → 6 ⇒ +4

So rule: Add 4 to the number

Apply:

  • 5 + 4 = 9

    Final Answer:

AS 9
