Answer 1

PLEASE MARK AS BRAINLIEST :)

Answer:

9680

Step-by-step explanation:

1st Case:

SI = 9200 - 8000 = 1200

t = 3

p = 8000

r = (SI * 100)/pt

or, r = (1200 * 100)/(8000 * 3)

or, r = 5

If r be 2% more i.e (5 + 2)= 7%

Then,

SI = (8000 * 7 * 3)/100

  = 1680

She would get = 8000 + 1680 = 9680
