Answer 2

Given:

A sum of RS. 4000 will yield a simple interest of Rs. 1200 at 12% per year

To find:

The time period

Solution:

To solve the given problem we will use the following formula of simple interest:

$\boxed{\bold{Simple\:Interest = \frac{PRT}{100} }}$

 

According to the given question, we have

P = Principal = Rs. 4000

R = Rate of interest  = 12 %

T = Time period = need to find

S.I. = Rs. 1200

Now, substituting the given values in the formula of simple interest, we get

$1200 = \frac{4000\:\times \:12\:\times \:T}{100}$

$\implies 120000 = 4000\:\times 12\: \times \: T$

$\implies T = \frac{120000 }{48000}$

$\implies \bold{T = 2.5 \:years}$

   

Thus, the time in which a sum of Rs. 4000 will yield a simple interest in Rs. 1200 at 12% per year is 2.5 years.
