Answer 1

Hlo

given in the question

principal = 12800

time = 1 year

rate = 7 and 1/2 % = 15/2%

find ci and amount semi annually

so 1 year = 2semi years

rate for semi year = (15/2)/2 = 15 /4

amount = p ( 1+r/100)n

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

= 12800 (1 + 3/80) 2

= 12800( 83/80)2

= 12800× 83/80×83/80

= 13778

so the amount is 13778 and the ci = a -p

13778- 12800 = 978

so the ci is 978
