'Hovercraft' task.

Question

I don't understand the task. How is it possible to have 'Loss' output for 5 hovercrafts if I spend 5*2mil+1mil=11mil and sell them for 5*3mil=15mil.
Profit: 4mil.

Answer 1

Read problem carefully. There they mentioned 10 hovercraft in a month.
Means they make 10 in a month with the cost of 2mil + 1mil so total cost will be 21mil but you sold 5 in a month with each 3mil so total selling cost will be 15mil.
So here is loss of 6mil.
