Official UPSC Answer KeyUPSC Prelims 2008 • General Knowledge (1995-2010)

Correct Answer: Option (C) — 183 × 10⁷ nanometres

Concept & Option Breakdown

Standard Reference Verified

1 foot = 30.48 cm = 0.3048 m. 6 feet = 6 × 30.48 cm = 182.88 cm = 1.8288 m. Since 1 m = 10⁹ nanometres, 1.8288 m = 1.8288 × 10⁹ nm = 182.88 × 10⁷ nm ≈ 183 × 10⁷ nanometres.
