You would like to invest 100,000 which you have received from your grandparents after your graduation. You have two different companies in which you can invest. You consider only the following 3 different possibilities to distribute your money. 1. You can invest in shares of company A only. If the economy remains stable shares of company A will generate [last non-zero digit of MN] % return. If things go very well 5% on top of that, while in times of crisis shares will lose [second last non-zero digit of MN] %. 2. You can invest in shares of company B only, leading to most likely return of [second last non-zero digit of MN] % in normal times, twice as much in good times and minus [last non-zero digit of MN]% in bad times. 3. Or, you can invest 50% in each of these companies.
