Question

ram gave rupee 5000 to Shyam at interest rate 12% per annum, after some time shyam returned rupee 8000 to ram, after how many year ram got his money back

Answer 1

given P=Rs.5000
Rate=12%
amount=8000
simple interest=8000-5000=3000
now SI =(P×R×T)/100
3000=(5000×12×T)/100
5000×12×T=3000×100=300000
T= 300000÷(5000×12)
=5
