Explanation:

- You have a bat and a ball with a price ratio of 9:5.

- This means if the ball costs 'x' rupees, the bat costs '9/5 * x' rupees.

- According to the problem, the bat costs Rs. 380 more than the ball.

- Form the equation: $(9/5)x=x+380$.

- Solve it: $9x=5x+1900$.

- Simplification gives: $4x=1900$.

- Solve for x: $x=475$.

- Option 3: Rs. 475 is the correct price of the ball.
