Question

At what time the sum Rs. 5000 will be doubled at the interest
of 10% per annum?​

Answer 1

Answer:

Time= $10$ years

Step-by-step explanation:

Let total time$=t$

Initial Amount$=5000$

Final Amount$=10000$

Total interest = Final Amount - Initial Amount

                      $=10000-5000\\=5000$

Simple Interest $=\frac{Initial Amount\times time\times rate}{100} \\\\5000=\frac{5000\times t \times 10}{100}\\\frac{t}{10} =1\\t=10 \ years$
