​

years=5/2

We know that,

R=(100×SI)/(P×T)

=(100×975)/(5200/×(5/2))

=(100×975×2)/(5200×5)

=(1×975×2)/(52×5)

=(195×1)/(26×1)

=(195/26)

=7.5

=7

Answer 2

Given: principle= 5200

simple interest= 975

time= 5/2years

To find: rate =?

Solution:

We will solve the question with the help of the formula of simple interest which is given below:

Simple Interest= Principle×rate×time

Now, putting the values given to the formula

we will get,

Simple interest= 5200×rate×(5/2)

975=5200×rate×(5/2)

rate=975/(5200×5/2)

rate=0.075

or, rate= 0.075×100= 7.5%

Hence, the rate is 7.5%
