Answer
Correct Answer: 3, 1, 4, 5, 6, 7, 2
Explanation
Introduction / Context:Reordering the visible spectrum by VIBGYOR is a common GK check. Given differently numbered colours, you must translate the mnemonic to the provided indices.
Given Data / Assumptions:
- Mapping: V(3), I(1), B(4), G(5), Y(6), O(7), R(2).
- Order sought: V → I → B → G → Y → O → R.
Concept / Approach:Write VIBGYOR using the provided index mapping, then transcribe the index sequence directly.
Step-by-Step Solution:
Sequence: V(3), I(1), B(4), G(5), Y(6), O(7), R(2).Hence: 3, 1, 4, 5, 6, 7, 2.Verification / Alternative check:Confirms standard spectrum order and consistent mapping to indices.
Why Other Options Are Wrong:They misplace one or more colours relative to the standard spectrum.
Common Pitfalls:Interchanging orange and red at the end.
Final Answer:3, 1, 4, 5, 6, 7, 2
