'RX-21' is related to 'UU-11' in a certain way. In the same way, 'PM-39' is related to 'SJ-29'. To which of the following is DP-17 related, following the same logic?

Question

Accepted Answer

Step 1: Analyze the letter pairs and numbers in the given examples.

Example 1: RX-21 → UU-11
Letters: R(18), X(24) → U(21), U(21)
Numbers: 21 → 11

Check the letter changes:
- R(18) to U(21): +3
- X(24) to U(21): -3 (since 24 - 3 = 21)

Number change: 21 to 11 → 21 - 10 = 11

Example 2: PM-39 → SJ-29
Letters: P(16), M(13) → S(19), J(10)

Letter changes:
- P(16) to S(19): +3
- M(13) to J(10): -3

Number change: 39 to 29 → 39 - 10 = 29

Pattern observed:
- First letter: +3 positions in alphabet
- Second letter: -3 positions in alphabet
- Number: subtract 10

Step 2: Apply the same logic to DP-17
Letters: D(4), P(16)

- First letter: D(4) + 3 = G(7)
- Second letter: P(16) - 3 = M(13)

Number: 17 - 10 = 7

So, DP-17 → GM-7

Hence, the correct answer is GM-7.
