(C) 10%

Answer 1

Answer:

a

Step-by-step explanation:

let us assume total 100 rs

it becomes 300 in 25 years

it means in 25 years we get 200 interest

so rate is actually total interset money we get in one year on rs 100

so if in 25 years we get 200 rs interest then in 1 year on rs 100 we will get 200/25 =8
