Question

Prove that >
PRT/100=I​

Answer 1

Answer:

Rs 125

Step-by-step explanation:

S.I =( P X R X T / 100 ).

Here, P = Principle.

R = Rate per annul.

T = Number of years.

Formula:

In case S.I ( Simple Interest ), T ( Number of years ) and R (Rate per annul ) are given in Question then we can easily find the Principle or Sum.

P = ( S.I X 100 / R X T ).

Formula:

In case S.I ( Simple Interest ), T ( Number of years ) and P ( Principle ) are given in question then we can easily find the R (Rate per annul ).

R = ( S.I X 100 / P X T ).

Example 1:

Find the simple interest on Rs 500 for 5 years at 5 per cent ?

Answer :

SI = 500 x 5 x 5 / 100

Simple interest in 5 years is Rs 125
