<p>I just got back.. THere was one problem where asia has 60% of the world population and 20% of world lnd mass. And find the population per square miles?</p>
<p>btw im prety sure the car tollbooth was 51...</p>
<p>For Asia population question: 300people per mile</p>
<p>Does anyone remeber the exact wording of the car tollbooth question. IT was like 80 cars went through the survey, some had 4 people some had 2 people some had just the driver. What is the greatest number of cars that passed through that had only the driver? Anyone.</p>
<p>There are 60 cars with a total of 83 passengers. Some contain only a driver, some a driver and one passenger, some a driver and three passengers. What is the highest number of cards with sole drivers. And it seems to be 51 for reasons unknown...</p>
<p>Wow. I got that grid-in completely wrong. I now see what I did wrong. When I redo it with those numbers i got 52.</p>
<p>that question was: at a booth thingy, 83 ppl were in 60 cars. only cars were with driver and three passengers (4ppl), driver and a passenger (2ppl), and driver only. What's the maximum number of cars with only one driver?</p>
<p>So i got 51.. and i just subtracted 83 by fours until i got to a match. so i did 83 -4x7 = 55 then just - 2x2 = 51 so nine cars passed, 51 cars left and 51 ppl left</p>
<p>Ya, i get 51, when i did the math, instead of subtracting a 2 person car, i used 3.</p>
<p>Theres 60 cars but 83 ppl. There are SOME (at least 2!!) 1 person in car, 2 ppl in car, and 4 ppl in car.</p>
<p>51(1) + 2(2) + 7(4) = 83</p>
<p>Why do those questions not sound in the least bit familiar to me? Im positive I didnt have those. Please someone give me an explantation</p>
<p>different tests.. as it turns out.. three versions are surfacing around the internet</p>
