Answer 1

Answer:

Compound Interest = P(1+ \frac{R}{100})^n - PP(1+

100

R

)

n

−P

Compound interest =Rs. 6655 , Principal amount = Rs. 5000 , rate of interest = 10%pa.

Substituting in the formula , we get

6655 = 5000(1+ \frac{10}{100})^n - 50005000(1+

100

10

)

n

−5000

6655 + 5000= 5000 (1.1)^n(1.1)

n

11655 = 5000 (1.1)^n(1.1)

n

(1.1)^n(1.1)

n

= 11655 / 5000

(1.1)^n(1.1)

n

= 2.331

(1.1)^n(1.1)

n

= (1.1)^3(1.1)

3

On comparing both sides , we get

n = 3

Therefore , the time period is 3 years.
