Question

7. In what time will 64,000 amount to 68,921 at
5% per annum, interest being payable half-yearly?

Answer 1

Answer:

$1 \frac{1}{2} years$

Step-by-step explanation:

===>CA = P (1+R/100)2t.

===>69821 = 64000(1+5/100)2t.

===>69821/6400=(41/40)2t.

===>(41/40)3 =(41/40)2t.

===>3= 2t.

===>t = 3/2.

===>t =3/2.

===>Hence the required time is :-

$1 \ \frac{1}{2}$
