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? Choose the correct choice from the following
A) 1200 B) 2877 C) 2779 D) 1770 E) 1887
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   1200nswer: 1200) Rs.1200
