Question

Question :- Simple interest of Rs 500 at the rate of 5% is Rs 100. This interest is of the time.

Answer 1

Given :-  

• Simple interest of Rs 500 at the rate of 5% is Rs 100.  

Find :-  

• Time period for which it was invested  

Solution :-  

~Here, we’re given the principal amount , rate of interest and Simple interest. We need to find the time for which the principal amount was invested. We can easily find the time by putting the values in the formula of simple interest ( SI ) .

_____________

As we know that ,  

$\boxed{\sf{ \maltese \;\;SI = \dfrac{P \times r \times T}{100}}}$

Where,  

• P is the principle amount [ Rs. 500 ]  
• r is the rate of interest [ 5 % ]  
• SI is the simple interest [ Rs. 100 ]  
• T is time which we need to find  

Finding the Time :-  

$\sf \implies 100 = \dfrac{ 500 \times 5 \times T }{100}$

$\sf \implies 100 = 5 \times 5 \times T$

$\sf \implies 100 = 25T$

$\sf \implies T = \dfrac{100}{25}$

$\sf \implies T = 4$

Hence,  

• The amount was invested for 4 years

Answer 2

Step-by-step explanation:

Simple Interest(SI)=500

Rate(R)=5% per annum

Principle(P)=₹100

Time=?

Formula:-

Time=SI×100

P×R

Time=500×100

100×5

=100 yrs.
