Question

In what time will Rs 8000 amount to Rs 8360 at 6% per annum simple interest?

a) 3/5 year
b) 1/5 year
c) 3/4 year​

Answer 1

Step-by-step explanation:

Simple interest = 8,360 - 8,000

= 360

I = 3/4

Answer 2

Answer:

The time period is $\frac{209}{12}$ years.

Step-by-step explanation:

Given : Principle amount = Rs. $8000$

          Simple interest = Rs. $8360$

          Rate of interest = $6$%

To find : Time period = ?

Solution :

• Here, it is given that  Principle amount = Rs. $8000$

                                 Simple interest = Rs. $8360$

                                 Rate of interest = $6$%

• We have to find the time period for which the interest was paid.
• We have a formula for simple interest,

      Simple interest = $\frac{P*r*t}{100}$

                   ∴ $8360=\frac{8000*6*t}{100}$

           ∴ $8360*100 = 48000*t$

                 ∴ $\frac{836000}{48000} = t$

                       ∴ $t = \frac{209}{12}$

• ∴ The time period is $\frac{209}{12}$ years.
