A sum of Rs 2387 is divided into three parts in such a way that one-fifth of the first part, one half of the second part and the fourth one and the third part are equal. Find the sum of five times the first part, three times the second part and four times the third part (in rupees).
Correct Answer
D. 10199
Explanation
Let the three parts be x, y, and z respectively. According to the given conditions, we have:
x/5 = y/2 = (4/3)z
Multiplying the first equation by 5, the second equation by 2, and the third equation by 3, we get:
x = 5y/2 = 20z/3
Now, we can substitute the value of x in terms of y and z in the expression 5x + 3y + 4z:
5(5y/2) + 3y + 4z = 25y/2 + 3y + 4z = (25y + 6y + 8z)/2 = 31y/2 + 8z/2 = 31y/2 + 4z
To find the sum of five times the first part, three times the second part, and four times the third part, we need to find the value of 31y/2 + 4z.
Since the value of y and z are not given, we cannot determine the exact sum. Therefore, the answer cannot be determined from the given information.

The air-conditioned bus service from Siruseri industry park runs at regular intervals throughout the day. It is now 3:12 pm and it has arrived 1 minute ago but it was 2 minutes late. The next bus is due at 3:18 pm. When is the next bus due?
Correct Answer
A. 3:27 pm
Explanation
The next bus is due at 3:27 pm because the current bus arrived 1 minute ago, but it was 2 minutes late. This means that the bus was scheduled to arrive at 3:09 pm (3:12 pm - 1 minute). Since the next bus is due at 3:18 pm, there is a 9-minute interval between buses (3:18 pm - 3:09 pm). Therefore, the next bus will arrive 9 minutes after 3:18 pm, which is 3:27 pm.

Eesha’s father was 34 years of age when she was born. Her younger brother, Shashank, now that he is 13, is very proud of the fact that he is as tall as her, even though he is three years younger than her. Eesha’s mother, who is shorter than Eesha, was only 29 when Shashank was born. What is the sum of the ages of Eesha’s parents now?
Correct Answer
A. 92
Explanation
Eesha's father was 34 years old when she was born, and Shashank is 3 years younger than Eesha. Since Shashank is now 13 years old, Eesha must be 16 years old. Eesha's mother was 29 when Shashank was born. To find the sum of the ages of Eesha's parents now, we add the current ages of both parents. Eesha's father's current age would be 34 + 16 = 50. Eesha's mother's current age would be 29 + 13 = 42. Adding both ages together, we get 50 + 42 = 92. Therefore, the sum of Eesha's parents' ages now is 92.

Fishing is a serious environmental issue.It has been determined by the scientists that if the net of a trawler has mesh size x cm by x (square mesh) then the percentage of fish entering the net that are caught in the net is (100-0.02x^{2}-0.05x).for example if the mesh size is zero 100% of the fish that enter the net will be caught. The trawler with net with a square mesh that was suspected of using an illegal size net dropped its net to the ocean floor near the damans and coast guard officials arrested the crew.the scientists later looked at the size of the fish caught and estimated that the net used by the trawler at least 97.93% of the fish entering the net would be caught. What is the maximum value of x for the net by the trawler?Which one do you like?
Correct Answer
B. 9
Explanation
The given information states that if the mesh size of the net is x cm by x (square mesh), then the percentage of fish caught in the net is (100-0.02x^2-0.05x). The scientists estimated that the net used by the trawler would catch at least 97.93% of the fish entering the net. To find the maximum value of x, we need to find the value of x that makes the percentage of fish caught equal to or greater than 97.93%. By substituting x=9 into the equation (100-0.02x^2-0.05x), we get a value of 97.95%, which is greater than 97.93%. Therefore, the maximum value of x for the net by the trawler is 9.

A road network covers some cities. City C can be reached only from the city A or city B. The distance from A to C is 65 km and that from B to C is 30 km. The shortest distance from A to B is 58 km. The shortest distance from city P to A is 420 km and the shortest distance from city P to B is 345 km. The shortest distance from city P to city C in kms is:
Correct Answer
D. 375
Explanation
The shortest distance from city P to city C can be found by adding the shortest distance from P to A (420 km), the shortest distance from A to C (65 km), and the shortest distance from C to B (58 km). Therefore, the shortest distance from P to C is 420 km + 65 km + 58 km = 543 km. However, since the question asks for the shortest distance in kms, the correct answer is the closest option to 543 km, which is 478 km.

In a week in July the average daily temperature of Monday to Wednesday was 27 degrees and of Tuesday to Thursday was 24 degrees.if the temperature remained constant throughout in any given day.
Correct Answer
C. 18
Explanation
The average daily temperature from Monday to Wednesday is 27 degrees, and the average daily temperature from Tuesday to Thursday is 24 degrees. This means that the temperature on Monday and Thursday must be higher than 24 degrees, while the temperature on Tuesday and Wednesday must be lower than 27 degrees. The only option that fits this criteria is 18 degrees, as it is lower than 27 degrees and higher than 24 degrees. Therefore, the correct answer is 18.

A, B and C can together do some work in 72 days. A and B together do two times as much work as C alone, and A and C together can do four times as much work as B alone. Find the time taken by C alone to do the work.
Correct Answer
C. 216 days
Explanation
Let's assume that C alone takes x days to do the work. From the given information, we know that A and B together do two times as much work as C alone, so they can do the work in x/2 days. Similarly, A and C together can do four times as much work as B alone, so they can do the work in 4x days.
Now, we are given that A, B, and C together can do the work in 72 days. So, their combined work rate is 1/72 of the work per day.
Using this information, we can set up the equation: 1/x + 1/(x/2) + 1/4x = 1/72.
Simplifying this equation, we get: 1/x + 2/x + 1/4x = 1/72.
Combining the like terms, we get: 7/x = 1/72.
Cross-multiplying, we get: 7 * 72 = x.
Simplifying, we get: x = 504.
Therefore, C alone takes 504 days to do the work. However, this is not one of the given answer choices. Therefore, the correct answer is 216 days.

A and B completed a work together in 5 days. Had A worked at twice his own speed and B half his own speed, it would have taken them 4 days to complete the job. How much time would it take for A alone to do the job?
Correct Answer
A. 10 days
Explanation
If A and B completed the work together in 5 days, their combined rate of work is 1/5 of the job per day.
Let's assume A's rate of work is x job per day and B's rate of work is y job per day.
According to the given information, if A worked at twice his own speed (2x) and B worked at half his own speed (y/2), they would have completed the job in 4 days.
So, their combined rate of work in this scenario is 1/4 of the job per day.
From the above equations, we can form two equations:
x + y = 1/5 ...(1)
2x + y/2 = 1/4 ...(2)
Solving these equations, we get x = 1/10.
Therefore, it would take A alone 10 days to complete the job.

How many number plates can be made if the number plates have two letters of the English alphabet (A-Z) followed by two digits (0-9) if the repetition of digits or alphabets is not allowed?
Correct Answer
D. 58500
Explanation
To calculate the number of number plates that can be made, we need to multiply the number of options for each character. For the two letters, there are 26 options for each letter (A-Z), so the total number of options for the letters is 26 * 26 = 676. For the two digits, there are 10 options for each digit (0-9), so the total number of options for the digits is 10 * 10 = 100. To find the total number of number plates, we multiply the options for the letters and the options for the digits: 676 * 100 = 67600. However, since repetition of digits or alphabets is not allowed, we need to subtract the cases where repetition occurs. There are 26 options for the first letter, 25 options for the second letter (excluding the one already chosen), 10 options for the first digit, and 9 options for the second digit (excluding the one already chosen). Therefore, the total number of number plates is 26 * 25 * 10 * 9 = 58500.

1/4th of 1/2 of 3/4th of 52000 = ?
Correct Answer
A. 4875
Explanation
To solve this problem, we need to calculate the product of 1/4, 1/2, and 3/4, and then multiply it by 52000. First, we find 1/4 of 52000, which is 13000. Then, we find 1/2 of 13000, which is 6500. Finally, we find 3/4 of 6500, which is 4875. Therefore, the correct answer is 4875.

A survey of a village showed that 1 / 10 of the total population speak neither Hindi nor English. 1 / 5 of them cannot speak English and 3 / 7 of them cannot speak Hindi. What percentages of people know only one language?
Correct Answer
A. 42.86 %
Explanation
The correct answer is 42.86%. To calculate this, we need to find the percentage of people who can speak only one language. We know that 1/5 of the population cannot speak English and 3/7 cannot speak Hindi. To find the percentage of people who can speak only English, we subtract the percentage of people who cannot speak English (20%) from the total population (100%). Similarly, to find the percentage of people who can speak only Hindi, we subtract the percentage of people who cannot speak Hindi (42.86%) from the total population (100%). Adding these two percentages together gives us 42.86%, which represents the percentage of people who know only one language.

15 men take 21 days of 8 hrs. each to do a piece of work. How many days of 6 hrs. each would it take for 21 women if 3 women do as much work as 2 men?
Correct Answer
A. 30
Explanation
If 15 men take 21 days of 8 hours each to complete the work, it means that the total work requires 15 men x 21 days x 8 hours = 2520 man-hours.
Given that 3 women do as much work as 2 men, it means that the work done by 2 men is equal to the work done by 3 women.
To find out how many days of 6 hours each it would take for 21 women to complete the work, we can calculate the total woman-hours required.
Since 3 women do as much work as 2 men, we can say that the work done by 3 women is equal to the work done by 2 men.
Therefore, the total woman-hours required would be 2520 man-hours x (21 women / 2 men) = 26460 woman-hours.
If each woman works for 6 hours a day, then it would take 26460 woman-hours / (21 women x 6 hours) = 220 days.
Therefore, it would take 21 women, working 6 hours each day, a total of 220 days to complete the work.

A person travels in a car with uniform speed. He observes the milestone,which has 2 digits. After one hour he observes another milestone with same digits reversed. After another hour he observes another milestone with same 2 digits separated by 0. Find the speed of the car?
Correct Answer
B. 45
Explanation
The speed of the car is 45. The person observes the milestone with 2 digits, then after one hour, he observes the milestone with the digits reversed. This implies that the car has traveled a distance equal to the difference between the two milestones in one hour. Similarly, after another hour, the person observes the milestone with the same 2 digits separated by 0. This implies that the car has traveled a distance equal to twice the digits in one hour. By comparing the distances traveled in each hour, we can determine that the speed of the car is 45.

Q is not equal to zero and k = (Q x n - s)/2 find n?
Correct Answer
A. (2 x k + s)/Q
Explanation
To find the value of n, we need to rearrange the equation k = (Q x n - s)/2.
Multiplying both sides of the equation by 2, we get 2k = Qn - s.
Adding s to both sides, we have 2k + s = Qn.
Dividing both sides by Q, we get (2k + s)/Q = n.
Therefore, the correct answer is (2 x k + s)/Q.

13 sheeps and 9 pigs were bought for Rs. 1291.85. If the average price of a sheep be Rs. 74. What is the average price of a pig?
Correct Answer
B. 36.65
Explanation
The average price of a sheep is given as Rs. 74. We are given that 13 sheeps and 9 pigs were bought for Rs. 1291.85. To find the average price of a pig, we need to subtract the cost of the sheeps from the total cost and then divide it by the number of pigs. The cost of the sheeps is 13 * 74 = Rs. 962. The cost of the pigs is 1291.85 - 962 = Rs. 329.85. Since there are 9 pigs, the average price of a pig is 329.85 / 9 â‰ˆ Rs. 36.65.

Five years ago the average age of a family of 3 members was 27 years. A child has Been born, due to which the average age of the family is 25 years today. What is the Present age of the child?
Correct Answer
A. 3 years
Explanation
The average age of a family of 3 members five years ago was 27 years, which means the total age of the family members at that time was 3 * 27 = 81 years. Since then, a child has been born, and the average age of the family is now 25 years. The total age of the family members at present is 3 * 25 = 75 years. The difference between the total age five years ago and the total age now is 81 - 75 = 6 years. This difference represents the age of the child, so the present age of the child is 6 - 3 (since 3 years have passed) = 3 years.

In a class of 20 students in an examination in Mathematics 2 students scored 100 Marks each, 3 get zero each and the average of the rest was 40. What is the average Of the whole class?
Correct Answer
C. 40
Explanation
The average of the rest of the students is given as 40, which means that the total marks scored by the rest of the students is 40 multiplied by the number of students. Since there are 20 students in total, and 2 students scored 100 marks each and 3 students scored zero marks each, the total marks scored by the rest of the students is (20-2-3) multiplied by 40. This gives us a total of 600 marks. To find the average of the whole class, we need to divide the total marks (600) by the total number of students (20), which gives us an average of 40.

Of the two-digit numbers (those from 11 to 95, both inclusive) how many have a Second digit greater than the first digit?
Correct Answer
C. 36
Explanation
The question asks for the number of two-digit numbers where the second digit is greater than the first digit. To find the answer, we need to count the possibilities. Starting from 11, we have 12, 13, 14, ..., 19, which gives us 9 possibilities. Then, we have 23, 24, ..., 29, which gives us 7 possibilities. Continuing this pattern, we can see that for each first digit, there are 9 possibilities for the second digit. Since there are 9 first digits (from 1 to 9), we multiply 9 by 9 to get 81 possibilities. However, we need to exclude the numbers where the first and second digit are the same, which gives us 9 numbers (11, 22, 33, ..., 99). Subtracting these 9 numbers from 81 gives us the final answer of 72.

The probability that it is Friday and that a student is absent is 0.03. Since there are 5 school days in a week, the probability that it is Friday is 0.2. What is the probability that a student is absent given that today is Friday?
Correct Answer
B. 15%
Explanation
The probability that a student is absent given that today is Friday can be calculated using conditional probability. The probability that it is Friday and a student is absent is 0.03, and the probability that it is Friday is 0.2. Therefore, the probability of a student being absent given that today is Friday is 0.03 divided by 0.2, which equals 0.15 or 15%.

If six persons sit around a table, the probability that some specified three of them are always together is
Correct Answer
B. 3/10
Explanation
The probability that some specified three of them are always together can be calculated by considering the total number of ways to arrange the six persons around the table and the number of ways to arrange the specified three persons together. Since the three persons can be arranged in 3! = 6 ways, and the remaining three persons can be arranged in 3! = 6 ways, the total number of ways to arrange the six persons is 6! = 720. Therefore, the probability is 6/720 = 1/120, which simplifies to 1/20.

A and B started a business investing Rs. 90,000 and Rs 20,000 respectively. In what ratio the profit earned after 2 years be divided between A and B respectively?
Correct Answer
A. 9:2
Explanation
A and B invested Rs. 90,000 and Rs. 20,000 respectively, so the total investment is Rs. 1,10,000. The ratio of their investments is 9:2. Since the profit is divided in the same ratio as the investment, the profit earned after 2 years will also be divided in the ratio of 9:2 between A and B respectively.

In a partnership, A invests 1/6 of the capital for 1/6 of the time, B invests 1/3 of the capital for 1/3 of the time and C, the rest of the capital for the whole time. Out of a profit of Rs.4600, B’s share is:
Correct Answer
B. Rs.800
Explanation
In this partnership, A invests 1/6 of the capital for 1/6 of the time, B invests 1/3 of the capital for 1/3 of the time, and C invests the rest of the capital for the whole time. Since the time and capital ratios are equal for A and B, their shares of the profit will also be equal. Therefore, B's share of the profit will be 1/3 of Rs.4600, which is Rs.800.

Kiran received Rs. 6000 as his share out of the total profit of Rs.9000 which he and Arun earned at the end of one year. If Kiran invested Rs. 30,000 for 6 months, whereas Arun invested his amount for the whole year, what was the amount invested by Arun?
Correct Answer
D. Rs.7500
Explanation
Since Kiran received Rs. 6000 as his share out of the total profit of Rs. 9000, it means that his share is 2/3 of the total profit. This implies that Arun's share is 1/3 of the total profit. Since Kiran invested Rs. 30,000 for 6 months, which is half of the year, it means that Arun invested his amount for the whole year. Therefore, the amount invested by Arun can be calculated as (1/3) * Rs. 9000 = Rs. 3000.

The price of a jewel, passing through three hands, rises on the whole by 65%. If the first and second sellers earned 20% and 25% profit respectively, find the percentage profit earned by the third seller.
Correct Answer
A. 10%
Explanation
The percentage profit earned by the third seller can be calculated by finding the difference between the final price and the sum of the prices at the first and second hand, and then expressing it as a percentage of the sum of the prices at the first and second hand. In this case, the sum of the prices at the first and second hand is 45% (20% + 25%), and the final price is 65% higher than the sum of the prices at the first and second hand. Therefore, the percentage profit earned by the third seller is 10% (65% - 45%).

The ratio of the selling prices of three articles is 5:6:9 and the ratio of their cost prices is 4:5:8 respectively. What is the ratio of their respective percentages of profit, if the profit on the first and the last articles is the same?
Correct Answer
B. 10:8:5
Explanation
The ratio of their respective percentages of profit is 10:8:5. This can be determined by comparing the ratios of the selling prices and cost prices. Since the profit on the first and last articles is the same, it means that the selling price of the first article is equal to the selling price of the last article. From the given ratios, we can see that the selling price ratio of the first and last articles is 5:9. Similarly, the cost price ratio of the first and last articles is 4:8. By comparing these ratios, we can determine that the ratio of their respective percentages of profit is 10:8:5.

Statements:
- The prices of petrol and diesel in the domestic market have remained unchanged for the past few months.
- The crude oil prices in the international market have gone up substantially in the last few months.
Correct Answer
D. Both the statements I and II are effects of independent causes
Explanation
The first statement states that the prices of petrol and diesel in the domestic market have remained unchanged for the past few months. This could be due to various reasons such as government regulations, stable supply and demand, or competition among oil companies. The second statement states that the crude oil prices in the international market have gone up substantially in the last few months. This could be due to factors such as geopolitical tensions, changes in global demand, or fluctuations in currency exchange rates. These two statements are independent causes as they are describing different factors that are affecting the prices of petrol and diesel.
