Question

In how many years will a sum of Rs. 800 at 10%
per annum compounded semi- annually become
Rs. 926.10?​

Answer 1

Answer:

1.5 years

Step-by-step explanation:

(926.10/800) = (1+(5/100))^2n. compounded half yearly ....rate becomes half ...and number of years becomes 2 times.

(92610/80000) = (21/20)^2n

(21/20)^3. = (21/20)^2n

that is. 2n = 3

n= 3/2

n=1.5 years
