A sum was put at simple interest at a certain rate for 6 years Had it been put at 4% higher rate, it would have fetched 144 more. Find the sum.	Choose the correct choice from the following options:  A) 500  B) 600  C) 700  D) 800  E) 900
Difference in S.I. = P×T/100(R1−R2)   ⇒ 144 = P×6x4/100(∵ R1 - R2 = 2)   ⇒ P = 144×100/6×4=600   Answer 600
