Rs 16,000 / 16,000 रुपये
3.
Rs 17,000 / 17,000 रुपये
4.
Rs 18,000 / 18,000 रुपये

Correct Answer: Rs 18,000 / 18,000 रुपये

For 2 years, CI − SI = P × (r/100)². So P = 180 ÷ (0.10)² = 180 ÷ 0.01 = 18,000. / 2 वर्षों के लिए, चक्रवृद्धि ब्याज − साधारण ब्याज = P × (r/100)²। अतः P = 180 ÷ (0.10)² = 180 ÷ 0.01 = 18,000।
