Answer 1

Answer:

R = 8%

SI = 4000

Step-by-step explanation:

1)

We know,

SI = PTR/100

Given,

SI = 8000

Principal,P = 25000

Time,T = 4years

To find,

Rate of interest,R = ?

Let's substitute the given values in the formula :-

8000 = 25000 x 4 x R/100

R = 8000 x 100/25000 x 4

R = 8 x 100/25 x 4

R = 2 x 100/25

R = 2 x 4

R = 8

Hence,

Rate of interest,R = 8%

2)

Given,

P = 12500

T = 4 years

R = 8%

To find,

SI = ?

We know,

SI = PTR/100

SI = 12500 x 4 x 8/100

SI = 125 x 4 x 8

SI = 4000

Hence,

Simple interest,SI = 4000
