A. 5 min B. 6 min C. 6 and 2/3 min D. 10 min E. 15 min Ratio of speed of jogger & walker = 10:6 Time taken to travel same distance for jogger & walker = 6:10 = 3:5 This 3 corresponds to 10 so multiplier is 10/3. So actual value of 5 is 5*10/3 = 50/3 mins

In the xyplane is the slope of line k equal to 0?
(1) The xintercept of k is 0. (2) The yintercept of k is 0

(1) The xintercept of k is 0. (2) The yintercept of k is 0 What is the source of this question? It is not very high quality. Each statement independently tells us that the line passes through (0, 0). So the line can be any line with non zero slope passing through the origin or it can be the x axis itself. But what would we consider the x intercept of x axis? Please send a screenshot of the question and official solution.

The link given above is locked because it is in the wrong forum but I did get to see the question. (Put problem solving questions in PS forum and Data sufficiency questions in DS forum) ABC is a 306090 triangle with sides 5  5*sqrt(3)  10 EDC will be another 306090 but here is the thing  it can have varying area. Say E is very very close to B. Then area of triangle EDC is much smaller than area of ABC. But say length of EC is same as length of AC. Then the two areas will be same. So the difference in the areas will vary. Do put up the official explanation of this question and let me know the source.

A. 4% B. 7% C. 10% D. 15% E. 40% Looking at the screenshot you sent, it looks like the question is exactly as you have written. I would suggest you to ignore this source since it seems to be very substandard. As for this question, if the red light holds, the car stops. If it changes, the car passes through. Probability that A and D turn while B and C hold = 0.5 * 0.6 * 0.7 * 0.2 = 4.2%

A. 800 B. 850 C. 900 D. 950 E. 1,000 I don't understand this question. It seems to say that one person runs 10 rounds outside and another person runs 10 rounds inside. If the difference in the circumference is 15 feet, the one outside will run 10*15 feet extra. If the difference of 15 feet is between radii or diameter, it will be different. The question needs to clarify properly.

Hi VeritasKarishma, Can you please tell me most important quant topics I need to cover. I have a booked GMAT next week. I thought I was good at quant so I concentrated mostly on my verbal ability. Now my mock score is only 45. My target is 50/51. I am ready to put in 100 hours this week.Thanks!
