定量分析
- 一个两位数的数字的乘积是 12。当从数字中减去 9 时,数字是相反的。号码是: 。
- 34
- 62
- 43
- 26
回答:
43
解释:
Let the ten’s and unit’s digit be x and y.
Then 10x + – 9 = 10 x + x
10×2 + 12 -9x = 120 + x2
9×2 – 9x – 108 = 0
x2 –x – 12 = 0
x2 –4x + 3x – 12 = 0
(x – 4) (x + 3) = 0
Therefore x = 4
Hence the required no. is 43 - 在每种情况下,除 17、23、35、59 以留下相同余数的最大数是哪个?

回答:

解释:
Required Number = HCF (23-17, 35-23, 59-35, 59-17)
= HCF (6, 12, 24, 42)
= 6 - 两个数字的比例为 5:7。如果他们的 LCM 是 105,那么他们的平方之间有什么区别?
- 261
- 210
- 72
- 840
回答:
216
解释:
Let ‘h’ be the HCF of the two numbers.
=> The numbers are 5h and 7h.
We know that Product of Numbers = LCM x HCF
=> 5h x 7h = 105 x h
=> h = 3
So, the numbers are 15 and 21.
Therefore, difference of their squares = 212 – 152 = 441 – 225 = 216 - A 单独和 B 单独完成一项工作分别比两者一起工作多 18 天和 8 天。如果两者一起工作,请找出所需的天数。
- 12
- 8
- 16
- 36
回答:
12
解释:
Let the time required to complete the work by A and B together = n days
=> Time required by A alone = n + 18 days
=> Time required by B alone = n + 8 days
Therefore, n2 = 18 x 8 = 144
=> n = 12
Hence, A and B require 12 days to complete the work if they work together. - 单独工作时,两个管道 A 和 B 分别需要比它们一起工作时多 9 小时和 6.25 小时来填充水池。如果两者一起工作,请找出填充池所需的总时间。
- 6
- 6.5
- 7
- 7.5
回答:
7.5
解释:
Let the time taken if both were working together be ‘n’ hours.
=> Time taken by A = n + 9
=> Time taken by B = n + 6.25
In such kind of problems, we apply the formula :
n2 = a x b, where ‘a’ and ‘b’ are the extra time taken if both work individually than if both work together.
Therefore, n2 = 9 x 6.25
=> n = 3 x 2.5 = 7.5
Thus, working together, pipes A and B require 7.5 hours. - 保罗必须行驶 24 公里。步行 1 小时 40 分钟后,他发现自己已经走完了剩余距离的 5/7。找出 Paul 的速度(以米/秒为单位)。
- 5/3 米/秒
- 7/5 米/秒
- 2/3 米/秒
- 8/5 米/秒
回答:
5/3 m/s
解释:
Let the required speed be x km/hr.
Distance covered by Paul in 1 hr 40 min = x × 100/60 = 5x/3 km.
Remaining distance = (24 – 5x/3) km.
Therefore, 5x/3 = 5/7 × (24 – 5x/3)
=> 7/5 × 5x/3 = 24 – 5x/3
=> 7x/3 = (72 – 5x)/3
=> 7x = 72 – 5x
=> 12x = 72 => x = 6.
Paul’s speed in meters per second = 6 × 5/18 = 5/3 m/s. - 彼得的快艇在静水中以 9 公里/小时的速度行驶。他划到距离105公里的地方,然后回到起点。如果溪流的速度为 1.5 公里/小时,请找出彼得所用的时间。
- 24 小时
- 21 小时
- 23 小时
- 22 小时
回答:
24 h
解释:
Upstream speed = 9 – 1.5 = 7.5 km/h.
Downstream speed = 9 + 1.5 = 10.5 km/h.
Therefore, time taken = 105/7.5 + 105/10.5 = 14 + 10 = 24 h. - 杰克消耗了他工资的 75%。后来他的工资增加了 20%,他的支出增加了 10%。找出他的储蓄增加的百分比。
- 51%
- 60%
- 50%
- 55%
回答:
50 %
解释:
Let Jack’s original salary be Rs 100. Then,
his expenditure = Rs 75,
his savings = Rs 25.
Now, his new salary = Rs 120. So,
new expenditure = (110/100) × 75 = Rs 165/2,
new savings = 120 – 165/2 = Rs 75/2.
Increase in savings = 75/2 – 25 = Rs 25/2.
Therefore, percentage increase in savings = (25/2)/25 × 100% = 50%.- Two numbers are in the ratio of 2:9. If their H. C. F. is 19, numbers are:
- 6, 27
- 8, 36
- 38, 171
- 20, 90
Answer:
Explanation:
Let the numbers be 2X and 9X
Then their H.C.F. is X, so X = 19
=> Numbers are (2×19 and 9×19) i.e. 38 and 171- At present father’s age is thrice of son’s age. After 15 years father’s age will be double of son’s age. What is son’s present age?
- 10 years
- 12 years
- 15 years
- 16 years
Answer:
Explanation:
Let the present age of son and father be x years and 3x years respectively.
Then (3x + 15) = 2(x + 15)
=> 3x + 15 = 2x + 30
=> x = 15
=> Son’s present age = x = 15 years.

如果如果x是金X闪烁和谓语金(x)为真谓闪烁(x)为真。以下哪一个逻辑公式代表了上述陈述?
- 一种
- 乙
- C
- D
- 乙
回答:
He will assume final responsibility
解释:
The statement “Not all that glitters is gold” can be expressed as follows :
¬(?x(glitters(x)?gold(x)) … (1)
Where ?x(glitters(x)?gold(x) refers that all glitters is gold. Now,
?x¬(glitters(x)?gold(x)) … (2), Since we know ¬?x() = ?x¬()
(Where => refers to -> All and ?x refers to -> There exists some).
As we know, A?B is true only in the case that either A is false or B is true. It can also defined in the other way :
A?B=¬A?B (negationA or B ) … (3)
From equation (2) and (3), we have
?x(¬(¬glitters(x)?gold(x))??x(glitters(x)?¬gold(x)) … (4), Negation cancellation ¬(¬) = () : and ¬(()?()) = (¬()?¬()) .
So Answer is (D) .

解释:
“eradicate” means “destroy utterly”
“distort” matches with “misrepresent”
“saturate” matches with “soak completely”
“utilize” matches with “use” - 科尼斯堡老城在第二次世界大战前曾是德国人占多数的城市,现在被称为加里宁格勒。战争结束后,加里宁格勒现在是俄罗斯领土,人口主要是俄罗斯人。它北临波罗的海,南面和西面分别与波兰和立陶宛接壤。从这段话中可以推断出以下哪些陈述?
- 加里宁格勒的民族构成历来是俄罗斯人
- 加里宁格勒是俄罗斯的一部分,尽管它与俄罗斯其他地区不相邻
- 柯尼斯堡更名为加里宁格勒,因为那是它原来的俄语名字
- 波兰和立陶宛正在从加里宁格勒到俄罗斯其他地区的路线上
回答:
Column 1 Column 2 1) eradicate P) misrepresent 2) distort Q) soak completely 3) saturate R) use 4) utilize S) destroy utterly
解释:
A is not true in the light of the given facts
- A is incorrect because the First line says that Kaliningrad (Koenigsberg before war) had a majority of the German population before the war. So, it was historically German and not Russian.
- B is correct as although Kaliningrad is not contiguous with the rest of Russia (being surrounded by countries of Poland in the south and west, Lithuania in the east and Baltic sea on the north), it has a predominantly Russian population.
- C cannot be inferred from the passage as it is nowhere in the passage what the original Russian name of Koenigsberg was.
- D is also not true because no data about the route is mentioned in the passage.
So, B is the correct option
- 印度北部被诊断出患有登革热(因蚊虫叮咬而感染)的人数是去年诊断人数的两倍。市政当局得出的结论是,该地区控制蚊子数量的措施失败了。以下哪一项陈述如果为真,与该结论不矛盾?
- 很大一部分受影响人口是从登革热流行的邻国返回的
- 由于市政办公室的行政效率提高,现在报告了更多的登革热病例
- 自从引入新的有效诊断测试以来,今年诊断出更多登革热病例
- 今年患有疟疾热(也因蚊虫叮咬而感染)的人数有所增加
回答:
1:S, 2:P, 3:Q, 4:R
解释:
- A contradicts the conclusion of the municipal authorities. So, A is not the correct choice.
- B is an incorrect choice because there is no data in the passage relating the reporting of cases and the efficiency of the administrative capabilities of the municipal authorities.
- C is also incorrect as it contradicts the conclusion of the municipal authorities.
- D is the correct choice as both malarial fever and dengue fever are caused by mosquito bite. If dengue fever had increased because of some other reason other than that concluded by the municipal authorities, then there would not have been an increase in the people with malarial fever. This statement supports the conclusion of the municipal authorities.
