Answer 2

Answer:

amount=24591.16, CI=6591.16

Step-by-step explanation:

principal=18000

rate=7%,12%,14%

time=3years

by using the formulae when the rate is at different %,

we get;

a=p(1+r1 by 100) ×(1+r2 by 100) ×(1+r3 by 100)

now by putting the value of r1,r2and r3, we get;

a=18000×107 by 100×112 by 100×114 by 100

by cancelling we get

a=3073996 by 125

a=24591.16

Ci=a-p

Ci=24591.16-18000

CI=6591.16
