Given:
- The bag contains Rs 510 in the form of 50 paise, 25 paise, and 20 paise coins.
- The ratio of the number of coins is 2:3:4.
To Find:
- The number of coins of each type.
Approach:
1. Let's assume the number of 50 paise coins = 2x.
2. The number of 25 paise coins = 3x.
3. The number of 20 paise coins = 4x.
Calculating the Total Value:
1. The value of 2x 50 paise coins = 2x * Rs 0.50 = Rs (1x).
2. The value of 3x 25 paise coins = 3x * Rs 0.25 = Rs (0.75x).
3. The value of 4x 20 paise coins = 4x * Rs 0.20 = Rs (0.80x).
4. The total value of all the coins = Rs 510.
Equation:
1x + 0.75x + 0.80x = 510
2.55x = 510
x = 510 / 2.55
x = 200
Calculating the Number of Coins:
1. The number of 50 paise coins = 2x = 2 * 200 = 400.
2. The number of 25 paise coins = 3x = 3 * 200 = 600.
3. The number of 20 paise coins = 4x = 4 * 200 = 800.
Therefore, there are 400 coins of 50 paise, 600 coins of 25 paise, and 800 coins of 20 paise in the bag.
- The bag contains Rs 510 in the form of 50 paise, 25 paise, and 20 paise coins.
- The ratio of the number of coins is 2:3:4.

Therefore, there are 400 coins of 50 paise, 600 coins of 25 paise, and 800 coins of 20 paise in the bag.
