Correct answer: C. 24
Explanation
597 × 10²² = 5.97 × 10²⁴ and 73.5 × 10²¹ = 0.0735 × 10²⁴. Adding, y = (5.97 + 0.0735) × 10²⁴ = 6.0435 × 10²⁴. So n = 24.597 × 10²² = 5.97 × 10²⁴ तथा 73.5 × 10²¹ = 0.0735 × 10²⁴। जोड़ने पर y = (5.97 + 0.0735) × 10²⁴ = 6.0435 × 10²⁴। अतः n = 24।More Mathematics & Numerical Ability questions
