- 两位数的数字与通过互换其数字的位置获得的数字之间的差是45。该数字的两位数之间的差异是什么? 。
- 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。如果其LCM为105,则它们的平方有什么区别?
- 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 - 分别工作的三个人A,B和C可以分别在10、12和20天内完成工作。他们决定一起工作,但是两天后,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了两颗紫胶,那就找出最高份额和最低份额的区别。

- 60000
- 10000
- 20000
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为11,而LCM为385。如果两个数字的相差不超过50,那么两个数字的总和是多少?
- 132
- 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连接到水箱。单独工作,它们分别需要10个小时,20个小时和30个小时。一段时间后,A关闭,再过2个小时,B也关闭。 C会再工作14个小时,以使水箱完全充满。找到关闭管道A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米的距离内看到一个小偷,并开始追赶他。小偷看到了他,也开始逃跑。如果小偷以8 km / hr的速度奔跑,而警察以10 km / hr的速度奔跑,请在警察抓住他之前找出小偷覆盖的距离。
- 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. - 一条船在静止的水中以13 km / h的速度行驶。如果溪流速度为4 km / h,向下游行驶68 km需要多少时间?
- 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. - 糖的价格降低了10%。结果,月销售额增加了30%。找出每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和C的当前年龄比例为4:5:9。九年前,他们的年龄总和为45岁。找到他们现在的年龄
- 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的当前年龄分别为3:4。 5年后,他们的年龄比例分别变为7:9。 Ashok的当前年龄是多少?
- 40年
- 28年
- 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

- 现代战争已从大规模的军队冲突变为对平民的压制。默默地工作的化学制剂似乎适合这种战争。令人遗憾的是,军事机构中有人认为化学试剂是实现其目标的有用工具。以下哪个陈述最能概括以上段落的含义:
- 现代战争导致内乱。
- 化学试剂可用于现代战争。

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.
