- 一个两位数和把它的数字位置互换得到的数的差是45。这个数的两位数有什么区别? .
- 5
- 7
- 6
- 都不是
回答:
5
解释:
Let the ten’s digit be x and unit’s digit be y
Then (10x + y) – (10y + x) = 45
9(x – y) = 45
x – y = 5 - 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?
- 216
- 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、B、C 三个人单独工作,分别可以在 10、12 和 20 天内完成一项工作。他们决定一起工作,但两天后,A离开了工作,又过了一天,B也离开了工作。如果他们在整个工作中总共得到两个 lacs,请找出最高和最低份额的差异。

回答:
70000
解释:
Let the total work be LCM(10, 12, 20) = 60 units
=> Efficiency of A = 60/10 = 6 units / day
=> Efficiency of B = 60/12 = 5 units / day
=> Efficiency of C = 60/20 = 3 units / day
Since the number of working days are different for each person, the share of each will be calculated in the ratio of the units of work done.
Now, A works for 2 days and B works for 3 days.
=> Work done by A = 2 x 6 = 12 units
=> Work done by B = 3 x 5 = 15 units
=> Work done by C = 60 – 12 – 15 = 33 units
Therefore, ratio of work done = 12:15:33 = 4:5:11
So, A’s share = (4/20) x 2, 00, 000 = Rs 40, 000
B’s share = (5/20) x 2, 00, 000 = Rs 50, 000
C’s share = (11/20) x 2, 00, 000 = Rs 1, 10, 000
Therefore, difference of the highest and lowest share = Rs 1, 10, 000 – 40, 000 = Rs 70, 000 - 两个数字的 HCF 是 11,它们的 LCM 是 385。如果数字相差不超过 50,那么这两个数字的总和是多少?

- 35
- 12
- 36
回答:
132
解释:
Product of numbers = LCM x HCF
=> 4235 = 11 x 385Let the numbers be of the form 11m and 11n,
such that ‘m’ and ‘n’ are co-primes.
=> 11m x 11n = 4235
=> m x n = 35
=> (m, n) can be either of (1, 35), (35, 1), (5, 7), (7, 5).
=> The numbers can be (11, 385), (385, 11), (55, 77), (77, 55).But it is given that the numbers cannot differ by more than 50.
Hence, the numbers are 55 and 77.
Therefore, sum of the two numbers = 55 + 77 = 132 - 三个管道 A、B 和 C 连接到一个储罐。单独工作,他们分别需要10小时、20小时和30小时。一段时间后,A 关闭,再过 2 小时,B 也关闭。 C 再工作 14 小时,使水箱完全装满。找出管道 A 关闭后的时间(以小时为单位)。

解释:
Let the capacity of the tank be LCM (10, 20, 30) = 60
=> Efficiency of pipe A = 60 / 10 = 6 units / hour
=> Efficiency of pipe B = 60 / 20 = 3 units / hour
=> Efficiency of pipe C = 60 / 30 = 2 units / hour
Now, all three work for some time, say ‘t’ hours.
So, B and C work for 2 more hours after ‘t’ hours and then, C works for another 14 hours.
=> Combined efficiency of pipe A, pipe B and pipe C = 11 units/hour
=> Combined efficiency of pipe B and pipe C = 5 units/hour
So, we have 11 x t + 5 x 2 + 14 x 2 = 60
=> 11 t + 10 + 28 = 60
=> 11 t = 60 – 38
=> 11 t = 22
=> t = 2
Therefore, A was closed after 2 hours. - 一名警察在 100 米外看到一个小偷,开始追他。小偷看到他,也开始逃跑。如果小偷以 8 公里/小时的速度奔跑,而警察以 10 公里/小时的速度奔跑,则在警察抓住小偷之前找出小偷走过的距离。
- 250米
- 400米
- 450米
- 350米
回答:
400 meters
解释:
We can safely assume that the policeman is running in the same direction as the thief.
Speed of policeman w.r.t thief = (10 – 8) = 2 km/hr.
Time taken by policeman to cover the 100m distance between him and the thief = (100/1000) / 2 = 1/20 hr.
Therefore, the distance covered by thief in 1/20 hrs = 8 × 1/20 = 2/5 km = 400 meters. - 一艘船在静水中以 13 公里/小时的速度行驶。如果溪流的速度为 4 公里/小时,向下游行驶 68 公里需要多长时间?
- 5 小时
- 4 小时
- 6 小时
- 3 小时
回答:
4 h
解释:
Speed of the boat downstream = 13 + 4 = 17 km/h.
Therefore, time taken to go 68 km downstream = (68/17) = 4 h. - 糖价下降10%。因此,每月销售额增加了 30%。找出月收入增加的百分比。
- 17%
- 19%
- 18%
- 都不是
回答:
17 %
解释:
Let the price of sugar be Rs 100 and monthly sales be 100 units. Then,
total revenue = 100 × 100 = Rs 10000.
And, new revenue = 90 × 130 = Rs 11700.
Increase in revenue = 11700 – 10000 = Rs 1700.
Hence, percentage increase in revenue = (1700/10000) × 100% = 17%. - A、B、C现在的年龄比例是4:5:9。九年前,他们的年龄总和是45岁。找出他们现在的年龄(以年为单位)
- 15、20、35
- 20、24、36
- 20, 25, 45
- 16、20、36
回答:
16, 20, 36
解释:
Let the current ages of A, B and C be ax years, 5x years and 9x respectively.
Then (4x-9) + (5x-9) + (9x-9) =45
=> 18x – 27 = 45
=> 18x = 72
=> x = 4
Present ages of A, B and C are 4x = 16, 5x = 20, 9x = 36 respectively. - Vinod和Ashok现在的年龄比例分别为3:4。 5年后,他们的年龄比分别变为7:9。 Ashok 现在的年龄是多少?
- 40年
- 28岁
- 32岁
- 36年
回答:
40 years
解释:
Let the present age of Vinod and Ashok be 3x years and 4x years respectively.
Then (3x+5) / (4x+5) = 7 / 9=> 9(3x + 5) = 7(4x + 5)
=> 27x + 45 = 28x + 35
=> x = 10
=> Ashok’s present age = 4x = 40 years

- 现代战争已经从大规模的军队冲突转变为镇压平民。默默工作的化学制剂似乎适合这种战争;遗憾的是,军事机构中有人认为化学制剂是他们事业的有用工具。下列哪一项最能概括上述段落的意思:
- 现代战争导致内乱。

回答:
People in military establishments like to use chemical agents in war.
解释:
Civil Strife means civil disorder, a term used to describe unrest caused by a group of people, which is not true in the light of the given passage. So, A is not the correct option. B is incorrect because there is no fact in the data justifying the use of chemical agents for warfare. C is also incorrect because it is mentioned in the second line that chemical agents appear to be suited for such warfare, which implies that they are desirable. It is mentioned in the last line that there exist people in military establishments who think that chemical agents are useful for warfare, which makes D correct.

Sentence – “she is adept at cutting through red tape” “accept” – verb Meaning – consent to receive or undertake (something offered). Sentence – “he accepted a pen as a present” Hence, only “adapt” goes right with the phrase described in the question.

回答:
mediocre
解释:
Here, superb and exhilarating would imply that the performance was brilliant. But, the fact that he could not understand why she got awarded the first prize indicates that her performance was not that amazing in his opinion. So, A and D are incorrect. Medium is more used as a noun, and denoted intermediate in quality, value, etc. So, B is incorrect Mediocre is used as an adjective (to represent quality) and means low in performance, i.e., normal and not extraordinary and C is the correct choice.
