If the compound interest (compounded Yearly) on a certain sum for 2 years at 3% is Rs.101.50 then what will be the corresponding simple interest?

a. Rs.98.25
b. Rs.100.00
c. Rs.90.00
d. Rs.95.50

• Ans is Option b.100
  simple interest=50+50
  compound interest=50+(50+50*0.3)=101.50

  HERE X IS PRINCIPLE
  101.50=X(1+3/100)^2 - X
  101.50=X(103/100)^2-X
  101.50=X[(103/100) -1]
  X=1015000/609.
  
  SI=PTR/100...............=(1015000*2*3)/(100*609).
  SI=100 EXACTLY.

• Ans. B
  
  years=2
  3%of 50= (50*(3/100))=Rs.1.5
  Simple Interest =50+50=100
  Compound Interest=50+50+1.5=101.5
