Question

3,000 amounts to 4,000 in 5 years at simple interest.​

Answer 1

Answer:

Step-by-step explanation:

Let the rate be r.

SI=P*T*r/100

1000=3000*5*r/100

1000/30*5=r

1000/150=r

20/3=r

Answer 2

Answer:

6.66% rate

Step-by-step explanation:

S.I= (P * R * T)/100   (where S.I = Amount - Principle )

4000 - 3000 = (3000 * 5 * R)/100

(1000 * 100) / (3000 * 5) = R

R = 6.6666
