Show answer & explanation

Correct answer: A. ₹ 170,000

Explanation

Extra simple interest = P × (extra rate) × time /100 = P × 1 × 3/100 = 3P/100. Setting 3P/100 = 5100 gives P = 5100 × 100 ÷ 3 = ₹1,70,000.अतिरिक्त साधारण ब्याज = P × (अतिरिक्त दर) × समय /100 = P × 1 × 3/100 = 3P/100। 3P/100 = 5100 रखने पर P = 5100 × 100 ÷ 3 = ₹1,70,000।
