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?	Options: A) Rs.1200 B) Rs.1300 C) Rs.1400 D) Rs.1500 E) Rs.1600
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 Rs.1200nswer: Rs.1200
