A sum was put at simple interest at a certain rate for 4 years Had it been put at 2% higher rate, it would have fetched 56 more. Find the sum. Choose the correct choice from the following answers
A) 500	B) 600	C) 700	D) 800	E) None of these
Difference in S.I. = P×T/100(R1−R2)   ⇒ 56 = P×4×2/100(∵ R1 - R2 = 2)   ⇒ P = 56×100/4×2=700   Answer 700
