Question

3. In what time will a sum of Rs.8000
become Rs. 9261 at the rate of 5% p
compounded annually.​

Answer 1

Answer:

P=8000

A=9261

R=10%

T=?

(A/Q- Interest compounded semi-annually)

A=P(1+R/200)^2T

9261 = 8000 (1+10/200)^2T

9261/8000 = (21/20)^2T

(21/20)^3 = (21/20)^2T

==> 2T = 3

T= 3/2

ANSWER :- 1 & 1/2 yrs.

or 18 months.
