Answer:

Time= [tex]10[/tex] years

Step-by-step explanation:

Let total time[tex]=t[/tex]

Initial Amount[tex]=5000[/tex]

Final Amount[tex]=10000[/tex]

Total interest = Final Amount - Initial Amount

                      [tex]=10000-5000\\=5000[/tex]

Simple Interest [tex]=\frac{Initial Amount\times time\times rate}{100} \\\\5000=\frac{5000\times t \times 10}{100}\\\frac{t}{10} =1\\t=10 \ years[/tex]
