Question

A sum of 3200rupees becomes 3456rupee in two years at a certain rate of simple interest. What is the rate of interest per annum?​

Answer 1

Answer:

Interest I=3456-3200 =256

P=Rs3200

N=2

R = 100xl/PN

= 100x256/3200x2=4%

Rate of interest=4%

Answer 2

Answer:

Step-by-step explanation:

The answer is 3200+(3200×x×2/100)=3456

3200+64x=3456

64x=3456-3200

x =256/64

x = 4

So the rate of interest is 4%
