At what rat per cent per annum simple interest will rs 3625 amaunt to rs 4495 in 2 years?

Answer 1

Answer:

Step-by-step explanation:

Principle (P)=₹3625

Amount (A)=₹4495

Now, Simple interest(SI)=A-P

=>SI=4495-3625

=>SI=₹870

Let Rate of interest=R% per annum

Time(T)=2 years

Now,R=SI×100/P×T

R=870×100/3625×2

R=12

So,Rate of interest= 12% per annum
