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.100 more. What was the Sum?
Choose the correct option
A) s.350
B) s.700
C) s.200
D) s.600
E) s.500
At 5% more rate, the increase in S.I for 10 years = Rs.100(given)   So, at 5% more rate, the increase in SI for 1 year = 100/10 = Rs.10/-   i.e. Rs.10 is 5% of the invested sum   So, 1% of the invested sum = 10/5   Therefore, the invested sum = 10 × 100/5 = Rs.200 Answer: s.200
