Are we in agreement now StockMoose? Let me know whats on your mind... I agree with your logic using those numbers to solve the problems, but I still don't understand why when 25% of the shift time is cut, an equivalent rise in the time it takes the job doesn't occur. Since it takes 12 days using 2 ...

Forget the multiplication by 1.5 for the time being A 1 shift = 1/24 A 1/2 SHIFT = 1/48 1/24 + 1/48 = 1/16 which is the same as multiplying by 1.5 B 1 shift 1/30 B 1/2 SHIFT 1/60 1/30 + 1/60 = 1/20 which is the same as multiplying by 1.5 Therefore in 1 day they do 1/16+1/20 = 9/80 Therefore to do 1...

Re: Rate problem (math issue)
SM16, It looks like you did not do any mistake. The answer should be D. Good work. Logitech, I was the one who said it should take 15 days, not 16 days. The 16 days is someone else's work. My question is, if you get 25% less shift (from 2 days to 1.5), then shouldn't it take exactly 25% more time t...

LCM // GCD inconsistency
If LCM * GCD = product, why is the following not working out? Using the numbers 15, 27, 50, the LCM is 1350. The GCD, on the other hand, is 1. If you multiply the GCD*LCM, you get 1350. However, the product of the 3 numbers (15, 27, and 50) is 2050. Why is there a discrepancy between the formula and...

I think the answer is D.
D) Since 1970, Deluxe has made fewer changes in the automobiles it manufactures than other car companies have made in their automobiles.
If Deluxe has made fewer changes than other companies, that implies the parts that make up the automobiles are more durable.

D simply says the nemotoids will emerge from the ground, it says nothing about them dying. B seems like the better choice, because it specifica...
