An economy consists of three workers, Larry, Moe, and Curly. Each works ten hours a day and can produce two services: mowing lawns and washing cars. In an hour, Larry can either mow one lawn or wash one car; Moe can either mow one lawn or wash two cars; and Curly can either mow two lawns or wash one car. Scenario 1: All three spend all their time mowing lawns. Then lawns will be mowed and cars will be washed. Scenario 2: All three spend all their time washing cars. Then lawns will be mowed and cars will be washedScenario 3: All three spend half their time on each activity. Then lawns will be mowed and cars will be washed. Scenario 4: Larry spends half his time on each activity, while Moe only washes cars and Curly only mows lawns. Then lawns will be mowed and cars will be washed. Exactly one of the scenarios above is inefficient. That is Scenario:

Larry spends half his time on each activity, while Moe only washes cars and Curly only mows lawns. Then lawns will be mowed and cars will be washed

Explanation:

In a hour :

Larry can ; wash 1 car or mow 1 lawn

Moe can ; mow 1 lawn or wash 2 cars

Curly can ; mow 2 lawns or wash 1 car

The inefficient scenario is  Larry spends half his time on each activity, while Moe only washes cars and Curly only mows lawns. Then lawns will be mowed and cars will be washed. this is because Larry can either wash 1 car or mow 1 lawn every hour and if Moe only washes cars and Curly only mows Lawns there will still be Cars and Lawns left to be washed and Mowed since Larry does not work at full capacity like Moe and Curly who could wash 2 cars or mow 2 lawns every hour

it's actually a very difficult task, due to not many people can make 2 million dollars in 2 years. besides that, to the not-so-realistic ideas, you can create a business. it could be practically anything, but make it into a business that isn't that known yet, you get me? also, lets not forget about stock market. that's where all the good stuff happens. use investments at the beginning and begin to raise up your business or whatever you're going to do. as this is a very non-realistic idea, it's still worth the shot!
