38. If STRONG is written as RTSONG in a code, what is the code for BRIGHT?

• A. RBIHTG
• B. RBIHGT
• C. RBITGH
• D. RBIGHT (Correct)

Explanation: Pattern: positions 1&2 are swapped, rest unchanged. S↔T→TS, T→R... STRONG: S-T swapped→TS, R,O,N,G = TSRONG? Let us try: STRONG→RTSONG means S and R swap positions (1st and 3rd). BRIGHT: B,R,I,G,H,T → swap B(1st) with I(3rd) → I,R,B,G,H,T = IRBGHT... alternate: positions 1&2 swap and 2&3 swap: S→R,T→T,R→S,O,N,G = RTSONG ✓. Apply to BRIGHT: B→R,R→B,I→I,G,H,T = RBIGHT .
