Answer 1

______✨ HEY MATE ✨______

===========
SOLUTION :-
===========

P = Rs. 3300 
A = Rs. 3399
R = 6% per annum
Let the time be n years.
Compound interest is taken half-yearly.
A = P*[1+ (R/2*100)]2n
3399 = 3300(1+3/100)2n
(1.03)2n = 3399/3300
(1.03)2n = (1.03)1
Thus, 2n = 1 year
n = 1/2 year = 6 months.

So , Option (A) is the right answer ✔️
