Detailed Solution

Given:
Weight of $100$ one rupee coin $= 485 g$

To find:
Weight of $10000$ coins

Calculation:
Weight of $1$ one rupee coin $= \frac{485}{100} = 4.85 g$

Weight of $10000$ coin $= 4.85 \times 10000 = 48500 g$

Since, $1 k g = 1000 g$ , we can write

Weight of $10000$ coin $= \frac{48500}{1000} = 48.5 k g$

Hence, correct answer is Option C.
