(2) 8 %
(3) 7 %
(4) 6%
show step by step​

Answer 1

Answer:

(4) 6%

Step-by-step explanation:

let Rate is R

interest on 800 = 800 * R * 2 / 100

= 16R

and interest on 500= 500* R *2 / 100

= 10R

given that interest on 800 is more than interest on 500 by 36

hence , 16R = 10 R + 36

6R = 36

R = 36/6 = 6 %
