Question

₹400 का 2 वर्ष का चक्रवृद्धि मिश्रधन ₹441 हो तो वार्षिक चक्रवृद्धि ब्याज दर कितना है

Answer 1

Answer:

5%

Step-by-step explanation:

Using the formula

A= P(1+r/100)^t where t is the time period in years r is the rate, P is the principal and A is the amount so

441=400(1+r/100)^2

441/400=(1+r/100)^2

(21/20)^2=(1+r/100)^2

21/20–1=r/100

1/20=r/100 so

R=5%
