The compound interest on a certain amount for 2 years at the rate of 8 p.c.p.a. is Rs.312. What will be the simple interest on the same amount and at the same rate and same time?

• S.I= 200
  ---------- * C.I
  200+r
  = 200
  -------- * 312
  200+8
  = 300 r.s

• given ,t=2 years,r=8%,c.i=312,
  as we know, the formula C.I.=Amount-Principal
  then
  312=P(1+R/100)^2-P
  312=P(1+8/100)^2-P
  312=P(108/100)^2-P
  312=P(11664/10000)-P
  312+P(11664/10000-1)
  312=P(1164/10000)
  312*10000=1164P
  3120000/1164=P
  P=1875
  S.I.=P*R*T/100
  1875*8*2/100
