Question

at what rate percent will the interest be half the principal in 10 years​

Answer 1

Answer:

Let the principal be P

Then, according to the question let the simple interest be S.I= P/2

Let rate of interest be r

Here time, t= 10 years

We know, S.I = P*r*t/100

=> P/2= P*r*10/100

=> R= 5

Hence the rate of interest would be 5 %
