-
- 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% - 9 years agoHelpfull: Yes(33) No(7)
- 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% - 8 years agoHelpfull: Yes(23) No(1)
- 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 - 8 years agoHelpfull: Yes(2) No(0)
- 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% - 7 years agoHelpfull: Yes(1) No(6)
- R=(100x3x31.25)/(468.75x5)
R=4% - 7 years agoHelpfull: Yes(0) No(1)
