Question

Simple interest on 1500 rupees at 7% per annum for a certain period is 210 rupees. Find the time period?

Answer 1

Answer:

2 years

Step-by-step explanation:

principal=rupees 1500

rate=7%

simple interest=principal*time*rate/100

210=1500*7*time/100

time=210/15*7

time=2 years

Answer 2

Given : Simple interest on 1500 rupees at 7% per annum for a certain period is 210 rupees.

To find : The time period.

Solution :

We can simply solve this mathematical problem by using the following mathematical process. (our goal is to calculate the time period)

Now, we know that :

Simple interest = (Principal amount × Rate of interest per annum × Time period)/100

In this case,

• Simple interest = Rs. 210
• Principal amount = Rs. 1500
• Rate of interest per annum = 7%
• Timer period = Let, t years

By, putting the available data in the above mentioned mathematical formula, we get :

210 = (1500 × 7 × t)/100

210 = 15 × 7 × t

15 × 7 × t = 210

105 × t = 210

t = 2

So, the time period = t years = 2 years

(This will be considered as the final result.)

Hence, the time period is 2 years
