The fixed cost if a small manufacturing company are #300000 .the variable costs, which are proportional to the sales are #1million.Calculate the total costs and the profit when the sales are #900000

To calculate the total costs, we need to add the fixed costs and the variable costs. The variable costs are proportional to sales, meaning that for every unit of sales, there is a constant ratio of variable costs.

Given:
Fixed costs = #300000
Variable costs = #1million (proportional to sales)
Sales = #900000

Total costs = Fixed costs + Variable costs

Variable costs = Constant ratio * Sales

Let's find the constant ratio first:
#1million = Constant ratio * #900000

Constant ratio = #1million / #900000
= 1.1111

Variable costs = Constant ratio * Sales
= 1.1111 * #900000
= #1000000

Total costs = Fixed costs + Variable costs
= #300000 + #1000000
= #1300000

To find the profit, subtract the total costs from sales:
Profit = Sales - Total costs
= #900000 - #1300000
= -#400000

The profit when the sales are #900000 is -#400000. Since the profit is negative, it means that the company incurs a loss of #400000.
