A sum was put at simple interest at a certain rate for 10 years. Had it been put at 5% higher rate, it would have fetched Rs.600 more. What was the Sum? A. Rs.1500 B. Rs.1400 C. Rs.1300 D. Rs.1200 Answer Workspace Report Discuss Answer with explanation Answer: Option D Explanation At 5% more rate, the increase in S.I for 10 years = Rs.600 (given) So, at 5% more rate, the increase in SI for 1 year = 600/10 = Rs.60/- i.e. Rs.60 is 5% of the invested sum So, 1% of the invested sum = 60/5 Therefore, the invested sum = 60 × 100/5 = Rs.1200 Workspace
