Question

In what time rs 800 amount to rs 882 at 5% per annum compound annually.

Answer 1

Answer:

principal= rs 800

amount= rs 882

rate of interest= 5% p. a

let time be n years.

A= P ( 1 +r/100)n

882 = 800(1 + 5/ 100)n

882/800= (1+5/100)n

441/400= (21/20)n

(21/20)∧2 = (21/20)∧n

now, since the bases are same

equating powers,

2=n

hence, time is 2 years
