Explanation:

- Let's first determine the number of each type of coin. If the ratio of the Rs2, Rs5, and Rs10 coins is 1:2:3 and there are 300 coins in total, we can set it up as:

- Rs2 coins = 1x

- Rs5 coins = 2x

- Rs10 coins = 3x

- Total coins equation: 1x + 2x + 3x = 300

- Solving for x gives x = 50.

- Now, calculate the number of each coin:

- Rs2 coins = 50

- Rs5 coins = 100

- Rs10 coins = 150

- Calculate the total amount of money:

- Amount from Rs2 coins = 50 * 2 = Rs100

- Amount from Rs5 coins = 100 * 5 = Rs500

- Amount from Rs10 coins = 150 * 10 = Rs1,500

- Total amount = Rs100 + Rs500 + Rs1,500 = Rs2,100

- Option 1: Rs2,100 is the correct answer.
