Answer:

  • Rate of interest = 5 %.
  • Compound interest = Rs. 630.5

Step-by-step explanation:

Given that,

  • Principal (P) = Rs. 4000
  • Amount (A) = Rs. 4630.50
  • Time (t) = 3 years

As we know,

↪ A = P(1 + R/100)^t

[ Putting values ]

↪ 4630.50 = 4000(1 + R/100)³

↪ 9261/2 = 4000(1 + R/100)³

↪ 9262/8000 = (1 + R/100)³

↪ (21/20)³ = (1 + R/100)³

↪ 21/20 = 1 + R/100

↪ 105 = R + 100

↪ R = 105 - 100

R = 5 %

No, we know,

↪ Compound interest = Amount - Principal

↪ Compound interest = Rs. (4630.50 - 4000)

Compound interest = Rs. 630.5

Answer:

r=5%

p=4000

a=4630.50

t=?

a=p(1+r/100)

Step-by-step explanation:

4630.50 = 4000(1+5/100)

=4630.50×2/4000×2

=9261/8000

=(21/20)³ = (21/20)

= 21 cancel by 21

=20 cancel by 20

= reamanig 3

Ans:- 3 year is your answer
