Verified Answer
A bag contains ₹510 in the form of 50 paise,25 paise and 20 paise coin...
Let the ratio be x.

Number of coins be 2x, 3x, 4x respectively.

(2x * 50P) + (3x * 25P) + (4x * 20P) = 510.

(2x * 0.50) + (3x * 0.25) + (4x * 0.20) = 510.

2.55x = 510.

x = 200.

So,

Number of 50P coin = 2 * 200 = 400.

Number of 25P coin = 3 * 200 = 600.

Number of 20P coin = 4 * 200 = 800.

A bag contains ₹510 in the form of 50 paise,25 paise and 20 paise coin...
Given:
- The bag contains ₹510.
- The bag contains 50 paise, 25 paise, and 20 paise coins.
- The ratio of the coins is 2:3:4.

To Find:
- The number of coins of each type.

Solution:

Step 1: Assign variables:
- Let's assume the number of 50 paise coins as 2x.
- Let's assume the number of 25 paise coins as 3x.
- Let's assume the number of 20 paise coins as 4x.

Step 2: Convert the ratio to the actual value:
- The value of 50 paise coins = 2x * 0.50 = 1x.
- The value of 25 paise coins = 3x * 0.25 = 0.75x.
- The value of 20 paise coins = 4x * 0.20 = 0.80x.

Step 3: Set up the equation:
- The total value of the coins = ₹510.
- Therefore, 1x + 0.75x + 0.80x = 510.
- Combining like terms, we get 2.55x = 510.

Step 4: Solve for x:
- Dividing both sides of the equation by 2.55, we get x = 200.

Step 5: Calculate the number of coins:
- The number of 50 paise coins = 2x = 2 * 200 = 400.
- The number of 25 paise coins = 3x = 3 * 200 = 600.
- The number of 20 paise coins = 4x = 4 * 200 = 800.

Answer:
- The number of 50 paise coins is 400.
- The number of 25 paise coins is 600.
- The number of 20 paise coins is 800.
