Answer 1

Answer:3.5%

Step-by-step explanation:

solution:

here,

p = 200

amont= 221

interest= p- amount

= 221-200

21

Now,

I = (p*t*r)/100

or, 21= (200*3*r)/100

or, r = 3.5%

Answer 2

Step-by-step explanation:

S.I = p*r*t/100

s.i= 200 -221

= 21

21 = 200*r*3/100

21 = 600*r/100

21 = 6r

21/6 = r

3.5% = r
