Explanation:
- The coins are in the ratio of 2:3:5 (for 50 p, 25 p, and 20 p respectively).
- Let the number of coins be 2x, 3x, and 5x.
- Money from 50 p coins: \(2x \times 0.50 = Rs. x.\)
- Money from 25 p coins: \(3x \times 0.25 = Rs. 0.75x.\)
- Money from 20 p coins: \(5x \times 0.20 = Rs. x.\)
- Total money: \(x + 0.75x + x = Rs. 2.75x = Rs. 550\).
- Solve for x: \(2.75x = 550\), \(x = 200\).
- Money from 50 p coins: Rs. 200.
- Money from 20 p coins: Rs. 200.
- Difference: Rs. 0.
- Correct Answer: Option 4, Rs. 0.
