Total sales Rs. 20,00,000; Fixed expenses Rs. 4,00,000; P/V Ratio 40%; Break-even capacity in percentage is .a.50% .b.40% .c.60% .d.45%.

The break-even point is the point at which total revenue equals total costs, resulting in neither profit nor loss. To calculate the break-even point in terms of capacity, we need to know the fixed costs and the contribution margin ratio (also known as the P/V ratio).

Here are the steps to calculate the break-even capacity:

1. First, calculate the contribution margin ratio. In this case, it is given as 40% or 0.40.

2. Next, calculate the break-even point in terms of sales. This is done by dividing the fixed costs by the contribution margin ratio. So, Rs. 4,00,000 / 0.40 = Rs. 10,00,000.

3. To find the break-even capacity as a percentage, divide the break-even sales by the total sales and multiply by 100. So, (Rs. 10,00,000 / Rs. 20,00,000) * 100 = 50%.

So, the break-even capacity in percentage is 50%. Therefore, the answer is .a.50%.
