Answer 1

Answer:

first we will find the rate of interest per annum

Rate = interest x 100/ principal time

= 800 x100/8000 x 1

= 10

rate = 10%

then find the compound interest of 2

years

C.I = A= 8000 ( 1+ 10/100 ) ( 1+ 10/100 )

= 8000x 11/10 × 11/10

= 9680

C.I = 9680 -8000

= 1680

let's find the compound interest of 3 years

C.I = A = 8000 ( 1+ 10/100 ) (1+ 10/100) (1 +

10/100 )

= 8000 x 11/10 x 11/10 x 11/10= 10648

C.I = 10648 - 8000

= 2648
