Given:
There are three types of coins Rs. 5, Rs. 10 and Rs. 20 coins
Total number of Rs. 20 coins = 7
Calculation:
Total number of Rs. 20 coins = 7
∴ The total amount of Rs. 20 coins = 7 × 20 = Rs. 140
The number of Rs. 20 coins are half of that of Rs. 10 coins.
Total number of Rs. 10 coins = 7 × 2 = 14
∴ Total amount of Rs. 10 coins = 14 × 10 = Rs. 140
The number of Rs. 5 coins is thrice that of Rs. 10 coins.
Total number of Rs. 5 coins = 14 × 3 = 42
∴ Total amount of Rs. 5 coins = 42 × 5 = Rs. 210
Total amount of the Rs. 5, Rs. 10 and Rs. 20 coins = (210 + 140 + 140) = Rs. 490
∴ Vaishnavi will have in total of Rs. 490.

Total number of Rs. 20 coins = 7
Calculation:
Total number of Rs. 20 coins = 7
∴ The total amount of Rs. 20 coins = 7 × 20 = Rs. 140
The number of Rs. 20 coins are half of that of Rs. 10 coins.
Total number of Rs. 10 coins = 7 × 2 = 14
∴ Total amount of Rs. 10 coins = 14 × 10 = Rs. 140
The number of Rs. 5 coins is thrice that of Rs. 10 coins.
Total number of Rs. 5 coins = 14 × 3 = 42
∴ Total amount of Rs. 5 coins = 42 × 5 = Rs. 210
Total amount of the Rs. 5, Rs. 10 and Rs. 20 coins = (210 + 140 + 140) = Rs. 490
∴ Vaishnavi will have in total of Rs. 490.

To solve this problem, let's use the given information step by step:
Step 1: Let's assume the number of Rs. 10 coins as 'x'.
So, the number of Rs. 5 coins would be 3x (as given in the question).
And the number of Rs. 20 coins is half of that of Rs. 10 coins, which means it is x/2.
Step 2: Now, we need to find the total amount Vaishnavi will have in her collection.
The value of each Rs. 5 coin is 5 rupees, each Rs. 10 coin is 10 rupees, and each Rs. 20 coin is 20 rupees.
Step 3: Calculate the total amount for each type of coin and then add them up.
Total amount from Rs. 5 coins = (value of each Rs. 5 coin) × (number of Rs. 5 coins) = 5 × (3x) = 15x
Total amount from Rs. 10 coins = (value of each Rs. 10 coin) × (number of Rs. 10 coins) = 10 × x = 10x
Total amount from Rs. 20 coins = (value of each Rs. 20 coin) × (number of Rs. 20 coins) = 20 × (7) = 140
Step 4: Add up the total amounts to find the total amount she will have in her collection.
Total amount = Total amount from Rs. 5 coins + Total amount from Rs. 10 coins + Total amount from Rs. 20 coins
Total amount = 15x + 10x + 140
Step 5: Simplify the expression.
Total amount = 25x + 140
Step 6: Substitute the given value of x into the expression.
Since the question doesn't provide the value of x, we cannot determine the exact total amount. However, we can conclude that the total amount will be a multiple of 25 (since it is multiplied by 25x).
Therefore, the answer cannot be determined with the given information.
Step 1: Let's assume the number of Rs. 10 coins as 'x'.
So, the number of Rs. 5 coins would be 3x (as given in the question).
And the number of Rs. 20 coins is half of that of Rs. 10 coins, which means it is x/2.
Step 2: Now, we need to find the total amount Vaishnavi will have in her collection.
The value of each Rs. 5 coin is 5 rupees, each Rs. 10 coin is 10 rupees, and each Rs. 20 coin is 20 rupees.
Step 3: Calculate the total amount for each type of coin and then add them up.
Total amount from Rs. 5 coins = (value of each Rs. 5 coin) × (number of Rs. 5 coins) = 5 × (3x) = 15x
Total amount from Rs. 10 coins = (value of each Rs. 10 coin) × (number of Rs. 10 coins) = 10 × x = 10x
Total amount from Rs. 20 coins = (value of each Rs. 20 coin) × (number of Rs. 20 coins) = 20 × (7) = 140
Step 4: Add up the total amounts to find the total amount she will have in her collection.
Total amount = Total amount from Rs. 5 coins + Total amount from Rs. 10 coins + Total amount from Rs. 20 coins
Total amount = 15x + 10x + 140
Step 5: Simplify the expression.
Total amount = 25x + 140
Step 6: Substitute the given value of x into the expression.
Since the question doesn't provide the value of x, we cannot determine the exact total amount. However, we can conclude that the total amount will be a multiple of 25 (since it is multiplied by 25x).
Therefore, the answer cannot be determined with the given information.
