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

FromTheMoon [43]

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