Help!! Manhattan SC "When to repeat and when not to
Hi guys. These feature in the Manhattan GMAT SC guide and didnt add up. "Many teachers choose to seek employment in the suburbs rather than face low salaries in the city". Why cant we have it this way :rather than to face low salaries in the city "The joint business venture will incre...

So you mean 100/25 equals 4.This 4 can be represented as 0.4 *10 to the power of 1.And this 0.4 is a terminated decimal.Is my understanding correct now? Thanks Sir.I was of the opinion that 4 was an integer.Do we represent that 4 as 4.0?Is this the mechanism that makes it a decimal? A little confuse...

Hey Brent In this particular problem Statement 1 says r is a factor of 100 1,2,4,5,10,25,20,50 and 100 are factors of 100 Now let s be equal to 4 and let r be 100 Now we have (r/s)=100/25 =4 Next lets have s=10 and r=2 (r/s)=0.2(non recurring) So I guess it should be insufficient because we could ge...

Thanks Patrick You are over-thinking it Daniel. Profit is always total revenues - total expenses. Think in real world terms. If you buy a toy for $100, and the manufacturer gives you a 50% refund, what did you actually spend? Only $50!. The problem with your formula is that at the end of the day, th...

Thanks Patrick,that was brilliant.I find it hard when it comes to identifying weights.Any tips for me? 50(2/5)+x(3/5)= 60 x=70 But the answer should be 75.Please explain this case and why weighted averages dont work here. Hi Daniel, The guys above explained good ways to solve; I just wanted to addre...

The question reads: A driver completed the first 20 miles of a 40-mile trip at an average speed of 50 miles per hour. At what average speed m...

Thanks for this,but the bigger question is:why my method doesnt get me the answer?
theCodeToGMAT wrote:First 20 miles
D = 20
S = 50
T = 2/5
Avg Speed = (40)/(2/5 + t)
60 ( 2/5 + t) = 40
24 + 60t = 40
t = 16/60 = 4/15
Speed = 20/4/15 = 75

The question reads: A driver completed the first 20 miles of a 40-mile trip at an average speed of 50 miles per hour. At what average speed must the driver complete the remaining 20 miles to achieve an average speed of 60 miles per hour for the entire 40-mile trip? -assume that the driver did not ma...
