A sum of Rs 468.75 was lent out at simple interest and at the end of 1 year and 8 months, the total amount of Rs 500 is received. find the rate of interest.

• Here P=468.75 which is the principle.
  Amount=Rs 500
  Amount =SI+P
  500=[468.75*(20/12)*R]/100 + 468.75
  31.25=156.25*5R/100
  R=4%

• 1 year 8 months=1(8/12)=1(2/3)=5/3 years he invest his money
  
  then S.I for 5/3 years
  
  given that p=468.75 A=500
  
  so S.I=500-468.75=31.25
  
  then r=S.i*100/p*t
  =31.25*100*3/468.75*5
  =4%

• 1 year 8 months=20 months.so increased in 20 months =31.25.so for 12 month 31.25*12/20=18.75.so rate of interest=18.75*100/468.75=4%

• Here P=468.75
  and total amount after 3 years is 500...so for the SI==Amount -P=31.25
  R=SI x 100 / P x Time
  Time= 1 year + 8/12=5/3
  so R= 31.25 x 100/468.75 x 5=== 4% ans

• P=468.75
  SI=500-468.75=31.25
  Using formula,
  SI=(p*r*t)/100
  here, t=(1+2/3) years
  so,31.25=(468.75*r*5/3)/100
  r=5%

• R=(100x3x31.25)/(468.75x5)
  R=4%
