Question

Rampal deposited * 25,000 in the bank for 4 years and obtained simple interest 8,000. What is the rate of simple interest? With the same rate and same period if he deposits amount 12,500, then how much interest he will get?​

Answer 1

Answer:

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 yes

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
