A sum was put at simple interest at a certain rate for 7 years Had it been put at 2% higher rate, it would have fetched 140 more. Find the sum.
Select the correct option
A) 500  B) 750  C) 1000  D) 1250  E) 1500
Difference in S.I. = P×T/100(R1−R2)   ⇒ 140 = P×7x2/100(∵ R1 - R2 = 2)   ⇒ P = 140×100/7×2=1000   Answer 1000
