Explanation:

- The motorcycle depreciates by 8% each year, meaning its value becomes 92% of the previous year's value.

- Let the present value be \( x \).

- After one year: \( 0.92x \)

- After two years: \( 0.92 \times 0.92x = 0.8464x \)

- According to the problem, after two years, the value will be Rs 84,640.

- Set up the equation \( 0.8464x = 84640 \).

- Solve for \( x \):

- \( x = \frac{84640}{0.8464} \)

- \( x = 100000 \)

- Option 4: 100000 is the correct answer.
