Question

Q18.Find time period if simple interest=Rs1050, rate=7%, principal= Rs5000 ​

Answer 1

Answer:

Step-by-step explanation:

Given,

          Rate of interest = 7%

          Principal = 5000

          Simple interest = 1050

To find,

          The time

Solution,

          S.I = $\frac{PRT}{100}$

          1050 = $\frac{5000*7*T}{100}$

            T = $\frac{1050*100}{5000*7}$

            T = 3

Therefore, the time period is 3 years

Answer 2

Answer:

Time period is $3$ years .

Step-by-step explanation:

To find : time period .  

Given: Simple interest = $Rs. 1050$  Principal amount = $Rs . 5000$ , Rate = $7\ \%$  ,

Solution :

• As per given data we know that , Simple interest is $Rs. 1050$ , Principal amount is $Rs . 5000$ , Rate is  $7\ \%$   .
• We know that , the simple Interest of an amount is calculated by multiplying the interest rate by the principal amount and the time period divided by $100$ .  

          SI Formula  : $S.I = \frac{P\times R\times T}{100}$

•  So, putting the value in formula we can find time period .  

           $1050 = \frac{5000\times 7\times T}{100} \\\\ 1050 = 50\times 7\times T\\\\ 1050 = 350 \times T\\\\ T= \frac{1050}{350} \\\\ T = 3$
