Answer 2

Answer: 8 years

Step-by-step explanation: Simple interest is given by

$S.I. =\dfrac{P\times R\times T }{100}$ where S.I. is simple interest, P is principal, R is rate of interest and T is time in years.

Now, given that P= 2000  A= 3600 R = 10

S.I. =Amount (A) - Principal = 3600-2000= 1600

Therefore:

$\Rightarrow1600=\dfrac{2000\times 10\times T}{100}\\\\\Rightarrow\dfrac{1600\times 100}{ 2000\times 10 } =T\\\\\Rightarrow8=T$

Hence, the answer is 8 years
