Answer 1

Here is your answer
P = Rs 12800
R = 15/2% pa =15/4% half yearly
T = 1 year = 2 = n for half yearly

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

= 12800 (1+15/4x 100)*2

= 12800(415/400)*2

= 12800 x415x415/400x400

= 128x415x415/1600

= 13778

CI = A - P. = 13778 - 12800

= 978

Amount = RS 13778

Compound Interest = Rs 978

Hope it helps you
