Question

The rate of interest at which amount of rs 5000 on simple interest. becomes rs 5800 in 2 years is

Answer 1

Amount= 5800
Principal= 5000
SI= 5800 - 5000
Si= 800

Si = p.r.t/100
800 = 5000.r.2/100
80000/5000 = 2r
2r = 16
R = 16/2
R = 8%
Hence rate is 8%

Answer 2

Answer:

Step-by-step explanation:

Amount= 5800

Principal= 5000

SI= 5800 - 5000

Si= 800

Si = p.r.t/100

800 = 5000.r.2/100

80000/5000 = 2r

2r = 16

R = 16/2

R = 8%
