Explanation:

- Original Price Calculation: Let the original price be 'x.' The price increased by 4%, making the final price Rs832. So, \( x + 0.04x = 832 \) simplifies to \( 1.04x = 832 \).

- Solving the Equation: Divide both sides by 1.04 to find x. So, \( x = \frac{832}{1.04} = 800 \).

- Option 1: Rs940 is incorrect because 4% increase of this amount results in Rs977.60, which is not Rs832.

- Option 2: Rs900 is incorrect as a 4% increase results in Rs936.

- Option 3: Rs812 is incorrect since a 4% increase leads to Rs844.48.

- Option 4: Rs800 is correct because increasing 800 by 4% results in precisely Rs832.
