let principal(p) be x
SI = (p*r*t)/100
where r is rate, t is time and SI is simple interest
amount = SI + principal (p)
SI = (x* 5*2)/100=x/10
Amount = 330 = x+ x/10
10x+x=3300
11x=3300
x=300
ans: principal (p)=300
SI = (p*r*t)/100
where r is rate, t is time and SI is simple interest
amount = SI + principal (p)
SI = (x* 5*2)/100=x/10
Amount = 330 = x+ x/10
10x+x=3300
11x=3300
x=300
