smart

I have a dream, my dream is to beat ETS! I will challenge it again! I will only list those questions that are not appeared on June’s jj, but if do list them, I do so to tell you guys what actual key the question is given


1. a, b, c are consecutive positive integers, and 0<a<b<c. is the product of these three integers divisible by 8 a) a and c are even b) b*c is divisible by 4 my key: c 2. gave a pattern, but the question basically asks how many integers between 1 and 60 do not have any factors that is same is 60, except 1. My key: 15 (I think it means any prime numbers that between 5 and 60) 3. a and b, starting from a same point, and going to same destination. Ask: how many minutes a arrive faster than b a) starting point and destination is 100 miles away b) a’s average speed is 5 mile faster than b’s average speed Key: E (I chose C, but I found out I were wrong right after I clicked confirm.) 4. question gave you a statistic tabular graph of a survey from 141 people, saying that it’s the distribution of xxx in age range. It asks: in which age range the median point falls into? The age 0-10 has 29 people, 10-20 has 27 people, 20-30 has 6 people, 30-40 has 3 people, 40-50 has 2 people, 50-60 has 4 people, 60-70 has xx people, 70-80 has xx people, 80 and above has 9 people. My key: I chose age of 80 or above, which is E 5. one whole set defined as choosing any three characters from {a, b, c, d, e, f, g, h} and distribute the set to people with no one gets more than one set. question said, 36 of the sets of the combination were left over (question specifically mentions that abc is different from bca). Ask, how many people are in there? My key: 300 6. 154 candies equally distributed to each of the kids and no left over. Which one can’t be the number of kids. My key: 40-50 (notice, there’s no such range as 30-40 in my question as other jj from this month) 7. 10gallons的 混 合 物 里 有 30%的沙 子 和 70% 别 的 东 东 ， 要 拿 走 一 部 份 混合 物 把 它 换 成 沙 子 ， 使 沙 子和 那 个 东 东 的 含 量 变 成 各 50%， 问approximately 要 加多 少 的 沙 子 (总 量 仍 是 10gallons)
My key: 2.9 (there’s no key as 20/7 my question)
8. The vetice of a triangle falls on (0,3), and this point is where the right angle located, another point located at (-4, 0), ask where does B located.
My key: (9/4, 0) (Please calculate to make sure, because I didn’t have time to do the calculation, so I guess this one)
9. 6 @ 3 <= 3, where @ denotes any symbol from addition, subtraction, multiplication, and division. Ask which one of them must be true.
I) 2 @ 2 = 1
II) 2 @ = 0
III) 4 @ 2 = 2
My key: C) which is only III (but this question is weird, because all of them could be true, but only III will get the same results no matter the sign is minus or divided.)
10. x, y, z. telling you that the arithmetic mean of these three number is 10, x <= y <= z, and z – x = 3. which one of the following could be the value of the median.
I)9
II) 10
III) 11
Note: this question is really weird in terms of it’s answers
a) I b)II c)III d)I and III e) I&II&III
my key: I chose C (I guess II is also correct, but the answer does not have f) II & III hehe. Because you can either assume the numbers be 8, 11, 11, in this case, 10 is the median, or 9, 9, 12, in this case, 11 is the median. Please correct me if I were wrong.)
11. x is positive, k = 0.1 + (0.1)^2. ask is x < 0.05
a) x < 0.009 / k
b) x > 0.0009 / k
Note: I forgot what the question asks, so I don’t want to mislead you guys with my key
12. is x > 13/11 ?
a) x > 1.182
b) x < 1.19
my key: A
13. x is 50% greater than y, z is 10% less than x, ask how many percent z is greater than y?
my key: 35%
14. a circular tank is measured to hold a maximum of 18 pai cubic feet of water, and the tank has the height of 2 feet. Ask what is the radius of the tank, in feet?
My key: 3 feet
15. one yard of robe is measure at 2.5 lb or ounce (I forgot the unit), ask what is the weight of one foott of robe ( 1 yard = 3 feets)
my key: 0.83
16. x is a two-digits integer. If ten’s of the digit is 6 times the unit digit. Ask what is x?
a) ten’s digit is 4
b) ten’s digit plus unit digit is another new two digits integer.
My key: C (might be E, not sure, because from the information, I guess x be 47)
17. one school only has undergraduate student, graduate student, and faculty member. If the ratio of undergraduate students per faculty member to the ratio of graduate students per faculty member is 1:20 (not accurate), what is the ratio of undergraduate students to graduate students?
a) tells you the ratio of undergraduate students per faculty
b) tells you the number of graduate students the school has
18. 1000 invest in a bank, and receive r% of interest compound semiannually. Ask what is the interest after a year?
My key: 1000 (0.25) r^2
19. f(x) = kx^3 + mx -1. when f(-7), result is 3. ask what is the result when f(7).
My key: -5
20. a sequence of number defined as: Xn = A + (n-1)d. First term is 54, 17^th term is 30. 25^th term is what?
My key: 18
Verbal
Writing: 1. the following memorandum is from the vice president of mama mia’s, italian’s restaurant:
“Last year, an editorial report shows that the 70% of the movie was targeted at teenage.

1. Klytz hypothesized that the caribou that live in northern area has longer leg and chest that has higher clearance than caribou that live in the aspen mountain, because northern area has deeper snow accumulation. It is so because the environment affect caribou at the north to evolutes to longer legs and chest clearance so that the caribou can eat xxx. Blah blah blah….. forgot.
