Correct Answer
A. 18Explanation
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.Rate this question:

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?
-
10 days
-
20 days
-
25 days
-
15 days
Correct Answer
A. 10 daysExplanation
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.Rate this question:

-
4875
-
4857
-
4785
-
4877
Correct Answer
A. 4875Explanation
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.Rate this question:

Q is not equal to zero and k = (Q x n - s)/2 find n?
-
(2 x k + s)/Q
-
(2 x s x k)/Q
-
(2 x k - s)/Q
-
(2 x k + s x Q)/Q (e) (k + s)/Q
Correct Answer
A. (2 x k + s)/QExplanation
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.Rate this question:

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?
-
3 years
-
5 years
-
4 years
-
7 years
Correct Answer
A. 3 yearsExplanation
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.Rate this question:

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?
-
30
-
35
-
40
-
45
Correct Answer
A. 40Explanation
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.Rate this question:

If six persons sit around a table, the probability that some specified three of them are always together is
-
1/20
-
3/10
-
1/5
-
4/5
Correct Answer
A. 3/10Explanation
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.Rate this question:

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:
-
Rs.650
-
Rs.800
-
Rs.960
-
Rs.1000

In a class of 60 students, the number of boys and girls participating in the annual sports is in the ratio 3 : 2 respectively. The number of girls not participating in the sports is 5 more than the number of boys not participating in the sports. If the number of boys participating in the sports is 15, then how many girls are there in the class?
-
20
-
25
-
30
-
Data Inadequate
Correct Answer
A. 30Explanation
Let's assume the number of boys participating in the sports is 3x and the number of girls participating is 2x. Given that the number of boys participating is 15, we can solve for x by setting up the equation 3x = 15. Solving for x, we find that x = 5. Therefore, the number of girls participating is 2x = 2(5) = 10. Since the number of girls not participating is 5 more than the number of boys not participating, we can calculate the number of boys not participating as 60 - 15 = 45. And the number of girls not participating is 45 + 5 = 50. Therefore, the total number of girls in the class is 10 + 50 = 60.Rate this question:

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.Rate this question:

-
153
-
478
-
403
-
375

A. 375Explanation
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.Rate this question:

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.
-
144 days
-
360 days
-
216 days
-
180 days
Correct Answer
A. 216 daysExplanation
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.Rate this question:

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?
-
56800
-
56500
-
52500
-
58500
Correct Answer
A. 58500Explanation
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.Rate this question:

Correct Answer
A. 45Explanation
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.Rate this question:

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.Rate this question:

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?
-
42.86 %
-
40 %
-
34 %
-
None of these
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.Rate this question:

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%.Rate this question:

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?
-
Rs.5000
-
Rs.6000
-
Rs.7000
-
Rs.7500
Correct Answer
A. Rs.7500Explanation
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.Rate this question:

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?
-
40
-
36.65
-
42
-
44
Correct Answer
A. 36.65Explanation
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 ≈ Rs. 36.65.Rate this question:

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?
-
4:5:6
-
10:8:5
-
5:6:9
-
Cannot be determined
Correct Answer
A. 10:8:5Explanation
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.Rate this question:

Correct Answer
A. Neither I nor II followsExplanation
The given statements state that no women teacher can play and that some women teachers are athletes. From these statements, we cannot conclude that male athletes can play, as there is no information given about male athletes. Similarly, we cannot conclude that some athletes can play, as the statements only mention women teachers who are athletes, not all athletes. Therefore, neither conclusion I nor conclusion II logically follows from the given statements.Rate this question:

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?
-
30
-
20
-
19
-
29
Correct Answer
A. 30Explanation
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.Rate this question:

Of the two-digit numbers (those from 11 to 95, both inclusive) how many have a Second digit greater than the first digit?
-
40
-
35
-
36
-
37
Correct Answer
A. 36Explanation
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.Rate this question:

Two bus tickets from city A to B and three tickets from city A to C cost Rs. 77 but three tickets from city A to B and two tickets from city A to C cost Rs. 73. What are the fares for cities B and C from A?
-
Rs. 4, Rs. 23
-
Rs. 13, Rs. 17
-
Rs. 15, Rs. 14
-
Rs. 17, Rs. 13
Correct Answer
A. Rs. 13, Rs. 17Explanation
Let the fare from city A to B be x and the fare from city A to C be y. From the given information, we can set up the following equations:
2x + 3y = 77
3x + 2y = 73
Solving these equations simultaneously, we find that x = 13 and y = 17. Therefore, the fares for cities B and C from A are Rs. 13 and Rs. 17 respectively.Rate this question:
