Question

A certain principal yeilds a simple interest equal to th of the principal after 2 years . Find the
rate of interest.

Answer 1

Given

Time= 2 years

To find = Rate of interest

solution:

Let the Principal be - X

As per question, S.I= P= X

we know that

S.I = (P*R*T)/100

X= (X*R*2)/100

R= 100X/2X

R= 50

Therefore, the required rate of interest is 50%. A certain principal yields a simple interest equal to that of the principal after 2 years at the rate of interest of 50%.
