GS-1 Physical Sciences Question 30

[abdshukair1376]

Is it advisable to not use an equation for this problem?
If you draw out a diagram, you see that it is impossible to add weight to the left of the fulcrum. Also, it is not a stretch to see that the 75 kg mass must be FURTHER than the 100 kg mass.

It might save time. Are the questions on the MCAT similar is difficulty?

Sometimes you can reason your way to a solution on the MCAT, and when it works, that's great. However, you need to know the relevant equations and how to apply them otherwise you could get burned on a more difficult question.

Are there "easy" questions on the real MCAT? Of course! In fact, at least 1/3 of real MCAT's this year will have some straight up question like what is the pH of 0.001 M HCl? If you can't calculate that it 0.2 seconds then you haven't studied chemistry. So the real MCAT has some give-aways but an average student ends up with an average score because most questions are not that simple.
