(d)8%​

Answer 1

Answer:

b= 10%

Step-by-step explanation:

let us assume the

amount =p

time =10 .....given

interest = p ......as given becomes amount

in simple interest

I=PTR/100

so

p=p*10*R/100

R=10

therefore the interest is 10

Answer 2

Answer:

(b) 10%

Step-by-step explanation:

Let the principal be P.

Amount = 2P

Simple Interest (S.I.) = 2P - P = P

Time (T) = 10 years

S.I. = PRT/100

=> P = P x R x 10 / 100

=> R = 10%
