Question

in how much time will be simple interest on a sum of money at 8%p.a. be 2/5 of the principal​

Answer 1

Answer:

Let the principal amount be X.

Then, SI=(2/5)of X= 2x/5.

Rate(R)=8%pa

To find: time(T)=?

We have SI= PTR/100

Or,T=SI×100/(PR)

= (2x/5)*100/(8x)

=200/40=5 years

Therefore, T= 5 years.
