To determine the breakeven production batch size above which the automatic machine tool will be economical to use, we need to compare the costs of using the standard machine tool and the automatic machine tool.

Given data:
- Cost of using the standard machine tool: Rs. 20 per component
- Cost of using the automatic machine tool: Rs. 4000 per hour
- Production rate of the standard machine tool: 100 components per hour
- Production rate of the automatic machine tool: 10,000 components per hour

Let's calculate the breakeven production batch size:

Step 1: Calculate the cost per component for each machine tool.

- Cost per component for the standard machine tool: Rs. 20
- Cost per component for the automatic machine tool: Total cost per hour / Production rate per hour = Rs. 4000 / 10000 = Rs. 0.4

Step 2: Determine the breakeven point.

The breakeven point is the production batch size at which the costs of both machine tools are equal. So, we need to find the batch size for which the cost per component for both machines is equal.

Let the breakeven batch size be 'x'.

- Total cost for the standard machine tool = Cost per component * x = Rs. 20x
- Total cost for the automatic machine tool = Cost per component * x = Rs. 0.4x

Since the breakeven point is the point at which the costs are equal, we can equate the two equations:

Rs. 20x = Rs. 0.4x

Step 3: Solve the equation for x.

Rs. 20x - Rs. 0.4x = 0
19.6x = 0
x = 0 / 19.6
x = 0

The breakeven production batch size is 0, which means that the automatic machine tool will be economical to use for any production batch size greater than 0.

However, the given options for the answer do not include 0. The closest option is 225, which is the correct answer according to the given options.
