**Problem Analysis**
We are given that Shivam has four times as many 5 rupee coins as 10 rupee coins. Let's assume that Shivam has N 10 rupee coins. We are required to find the number of 5 rupee coins he has.

**Plan**
To solve this problem, we can follow these steps:
1. Calculate the number of 5 rupee coins using the given information.
2. Write an equation to represent the relationship between the number of 5 rupee coins and the number of 10 rupee coins.
3. Solve the equation to find the number of 5 rupee coins.

**Step 1: Calculate the number of 5 rupee coins**
We are given that Shivam has four times as many 5 rupee coins as 10 rupee coins. Let's assume that Shivam has N 10 rupee coins. According to the given information, the number of 5 rupee coins will be 4 times N.

**Step 2: Write an equation**
Let's represent the number of 10 rupee coins as N and the number of 5 rupee coins as 4N. We can write the equation as:
Number of 5 rupee coins = 4 times Number of 10 rupee coins

Mathematically, this equation can be represented as:
4N = 40

**Step 3: Solve the equation**
To solve the equation, we can divide both sides by 4:
4N/4 = 40/4
N = 10

Therefore, Shivam has 10 rupee coins.

Now, let's substitute the value of N into the equation to find the number of 5 rupee coins:
Number of 5 rupee coins = 4N = 4 * 10 = 40

Therefore, Shivam has 40 5 rupee coins.

**Final Answer**
Shivam has 40 5 rupee coins.

Ans =

Shivam has four times as 5 rupee = 4 × 5 = 20 rupee.

Shivam has four times as 10 rupee = 4 × 10 = 40 rupee.
