Answer 1

$\mathfrak{Answer:}$

10 years.

$\mathfrak{Step-by-step\:explanation:}$

Given :

• Principle = Rs. 7320.
• Amount = Rs. 13176.
• Rate = 8% p.a.

Let the time be n years.

We know that ,

$\boxed{\bold{Amount-Principle=SI=\dfrac{Priniple \times Time \times Rate}{100}}}\\\\\\\implies\bold{13176-7320=\dfrac{7320 \times n \times 8}{100}}\\\\\\\implies\bold{5856=\dfrac{7320 \times n \times 8}{100}}\\\\\\\implies\bold{n=\dfrac{5856 \times 100}{7320 \times 8}=10.}\\\\\\\boxed{\boxed{\bold{Time=n=10\:years.}}}$
