Question

if 6400 is invested at a compound interest at the rate of 25/4%per annum the amount after 2 year​

Answer 1

Answer:

7225

Step-by-step explanation:

Principal ( P ) : 6400

Rate ( R ) : 25 / 4 %

Time ( n ) : 2 years

Amount = P ( 1 + R / 100 $)^{n}$

             = 6400 ( 1 + 25 / 400 $)^{2}$

             = 6400 x 17/16 x 17/16

             = 7225
