solar power vs wind power
Question of math genius please help!?
Researchers 1.even-T, U, V, W, X, Y and Z are assigned to prepare a report on a certain kind of energy source. Their topics include hydroelectric, wind, solar, geothermal, nuclear, coal and natural gas. Each investigator is assigned by the following rules: T is assigned one of hydro, solar or geothermal. U is assigned either solar or energy nuclear. V can cover any subject, except for geothermal energy. W and X are assigned to one of wind energy, coal or natural gas. Y and Z can cover all issues, but if Y or Z is nuclear or hydroelectric power, then the other is the other thing. Z is assigned hydropower. If Z, W and X are assigned hydro, coal and natural gas, respectively, all of the following are true EXCEPT: a solar energy) U is assigned. b) V is assigned to wind energy. c) T is assigned the energy solar. d) and assigned nuclear power. e) T is assigned the geothermal energy.
He says that Z has hydro. W is for coal. X has natural gas. He was also told one of the statements that, if Y or Z is hydroelectric, the other must be nuclear. And so it was nuclear. U must have solar or nuclear energy, but since we now have nuclear, solar U has. T must take into hydropower, solar, geothermal, but since two of these are taken, T must have geothermal. That leaves V in the wind. Summary: T = U = V = wind solar geothermal W = X = Y coal natural gas = Z = nuclear hydro is now obvious that if assigned statement false c) V solar
