Answer 1

IN bank = 2360-2000  = 360

T= 3 yrs  

simple interest per annum = 360/3 = 120

IN post office = 2480-2000 = 480

T= 3 yrs  

simple interest per annum = 480/3 = 160

Ratio = 120/160 = 3:4

Answer 2

Step-by-step explanation:

interest by bank = 2360-2000=360 for 3 years

interest % = 360 x 100/(2000 x 3)= 6%

interest by bank = 2480-2000=480 for 3 years

interest % = 480 x 100/(2000 x 3)= 8%
