A SUM DOUBLES ITSELF IN 10 YEARS AT SIMPLE INTREST,WHAT IS THE P,C,P,A RATE OF INTREST

• Rate of interest=10 %
  Sum doubles when interest=principal or sum
  For the sum to double in 10 years r*10=100 -> r=10

• If p is principal and r is rate of interest in PCPA, then
  p*r*10/100 = P
  r= 10 pcpa
• 11 years agoHelpfull: Yes(1) No(3)
• simple interest s.i=p*t*r/100
  so,r=s.i*100/p*t
  let s.i=x,p=2x,t=10
  r=x*100/2x*10
  r=5%,so rate is 5%

• r=n-1/t*100
  n=2,t=10
  r=2-1/10*100=10
  r=10%
