Answer 1

Step-by-step explanation:

A = P ( 1 + R/100)^n

P = Rs. 12,800;

R = 15/2% p.a. = 15/4 % half-yearly

T = 1 year;

n = 2 ( 2 half-years make 1 year)

So,

A = 12,800 ( 1+ (15/4)/100) ^ 2

= 12,800 ( 1 + 15/400)^ 2

= 12,800(415/400)^2

= 12,800 * (1,72,225/1,60,000)

= Rs.13,778

C.I. = 13,778 - 12,800

= Rs.978
