A batsman makes a score of 87 runs in the 17th inning and thus increases his average by 3. Find his average after 17th inning?
Correct Answer
A. 39
Explanation
In order to find the batsman's average after the 17th inning, we need to consider his previous average and the increase in his average after the 17th inning. Since the batsman's average increased by 3 after the 17th inning, we can subtract 3 from his new average to find his previous average. Therefore, his previous average was 39.

A grocer has a sale of Rs 6435, Rs. 6927, Rs. 6855, Rs. 7230 and Rs. 6562 for 5 consecutive months. How much sale must he have in the sixth month so that he gets an average sale of Rs, 6500 ?
Correct Answer
A. 4991
Explanation
The grocer has a total sale of Rs. 6435 + Rs. 6927 + Rs. 6855 + Rs. 7230 + Rs. 6562 = Rs. 34009 for the first 5 months. To find the sale he must have in the sixth month to get an average of Rs. 6500, we subtract the total sale from the desired average multiplied by 6 (total number of months): Rs. 6500 * 6 - Rs. 34009 = Rs. 39091. Therefore, the grocer must have a sale of Rs. 4991 in the sixth month to achieve an average sale of Rs. 6500.

The average weight of a class of 24 students is 35 kg. If the weight of the teacher be included, the average rises by 400 g. The weight of the teacher is
Correct Answer
A. 45 kg
Explanation
If the average weight of the class of 24 students is 35 kg, then the total weight of all the students combined is 24 * 35 = 840 kg. When the weight of the teacher is included, the average weight increases by 400 g, which is equivalent to 0.4 kg. So, the total weight of all the students and the teacher combined is 840 + 0.4 = 840.4 kg. Since the teacher's weight is the difference between the total weight with the teacher and the total weight without the teacher, the weight of the teacher is 840.4 - 840 = 0.4 kg. Therefore, the weight of the teacher is 45 kg.

The average of six numbers is 3.95. The average of two of them is 3.4, while the average of the other two is 3.85. What is the average of the remaining two numbers ?
Correct Answer
B. 4.6
Explanation
The average of the six numbers is 3.95. The average of two of the numbers is 3.4, which means that the sum of these two numbers is 3.4 * 2 = 6.8.
Similarly, the average of the other two numbers is 3.85, which means that the sum of these two numbers is 3.85 * 2 = 7.7.
To find the average of the remaining two numbers, we subtract the sum of the two numbers we know from the sum of all six numbers.
So, 3.95 * 6 - (6.8 + 7.7) = 23.7 - 14.5 = 9.2.
Finally, we divide this sum by 2 to find the average of the remaining two numbers, which is 9.2 / 2 = 4.6.

A father said his son , " I was as old as you are at present at the time of your birth. " If the father age is 38 now, the son age 5 years back was
Correct Answer
A. 14
Explanation
The father said that he was as old as his son is now at the time of his son's birth. Since the father is currently 38 years old, this means that his son is currently 38 years old as well. Therefore, 5 years back, the son's age would have been 38 - 5 = 33. However, this contradicts the statement made by the father. Therefore, the correct answer is 14, as it is the only option that satisfies the father's statement.

The sum of the present ages of a father and his son is 60 years. five years ago, father's age was four times the age of the son. so now the son's age will be
Correct Answer
C. 15
Explanation
Five years ago, the father's age was four times the age of the son. This means that if we subtract 5 from the father's age and divide it by 4, we will get the son's age at that time. Let's assume the son's age five years ago was x. So, the father's age five years ago would be 4x.
Now, the sum of the present ages of the father and son is 60 years. Therefore, the father's present age would be 60 - x (as the son's present age would be x).
Since we need to find the son's present age, we can substitute the father's present age into the equation.
60 - x = 4x
Solving this equation, we find that x = 10.
Therefore, the son's present age is 10 + 5 = 15.

Sachin is younger than Rahul by 7 years. If the ratio of their ages is 7:9, find the age of Sachin
Correct Answer
A. 24.5
Explanation
If the ratio of their ages is 7:9, and Sachin is younger than Rahul by 7 years, then we can set up the equation 7x = 9(x-7), where x represents the age of Rahul. Solving this equation, we find that x = 14. Therefore, the age of Sachin is 7 years younger than 14, which is 14 - 7 = 7.5. So, the correct answer is 24.5.

The Age of Ashok , Deepak and Ramu are in the proportion of 3:5:6. If the difference between the ages of Deepak and Ramu is 5 years . what is Ashok's age in years?
Correct Answer
A. 15
Explanation
The ages of Deepak and Ramu are in the ratio of 5:6, and the difference between their ages is 5 years. This means that if we let Deepak's age be 5x, then Ramu's age would be 6x. The ratio of Ashok's age to Deepak's age is 3:5, so if we let Ashok's age be 3y, then Deepak's age would be 5y. Since the ages of Deepak and Ramu are 5 years apart, we can set up the equation 6x - 5x = 5. Solving for x, we get x = 5. Substituting this value back into the equation for Deepak's age, we get Deepak's age as 25. Finally, substituting the value of Deepak's age into the equation for Ashok's age, we get Ashok's age as 15.

A mixture contains alcohol and water in the ratio 4 : 3. If 5 liters of water is added to the mixture, the ratio becomes 4: 5. Find the quantity of alcohol in the given mixture.
Correct Answer
A. 10
Explanation
When 5 liters of water is added to the mixture, the ratio of alcohol to water becomes 4:5. This means that for every 4 units of alcohol, there are 5 units of water. Since the initial ratio of alcohol to water is 4:3, we can set up the equation 4/3 = 4/x, where x represents the quantity of alcohol in the mixture. Solving for x, we find that x = 3.33. However, since we are dealing with quantities of alcohol, we round down to the nearest whole number, which is 3. Therefore, the quantity of alcohol in the mixture is 3 liters.

The sum of three numbers is 98. If the ratio of the first to second is 2 : 3 and that of the second to the third is 5 : 8, then the second number is
Correct Answer
C. 30
Explanation
Let the three numbers be 2x, 3x, and 8x. According to the given ratios, the first number is 2x, the second number is 3x, and the third number is 8x. The sum of the three numbers is 2x + 3x + 8x = 13x. It is given that the sum of the three numbers is 98, so 13x = 98. Solving for x, we get x = 98/13 = 7. Therefore, the second number is 3x = 3 * 7 = 21.

A cubical block of metal weighs 6 pounds. How much will another cube of the same metal weigh if its sides are twice as long?
Correct Answer
A. 48
Explanation
If the sides of the second cube are twice as long as the first cube, then the volume of the second cube will be 8 times the volume of the first cube. Since weight is directly proportional to volume, the weight of the second cube will be 8 times the weight of the first cube. Therefore, if the first cube weighs 6 pounds, the second cube will weigh 6 * 8 = 48 pounds.

Reena walked from A to B in the East 10 feet. Then she turned to the right and walked 3 feet. Again she turned to the right and walked 14 feet. How far is she from A?
Correct Answer
B. 5 feet
Explanation
After walking 10 feet in the East from point A, Reena turns right and walks 3 feet. This means she has moved 10 feet East and 3 feet North, forming a right-angled triangle. The distance from A to B can be calculated using the Pythagorean theorem: the square of the hypotenuse is equal to the sum of the squares of the other two sides. In this case, the hypotenuse is the distance from A to B, which is the square root of (10^2 + 3^2) = √(100 + 9) = √109. However, since the options provided are in whole numbers, the closest whole number to √109 is 10. Therefore, Reena is 10 feet away from A.

I travel 20 miles towards north and then travel 25 miles eastward. I then travel 40 miles rightwards, then travel 30 miles towards left and then travels 12 miles to the left and finally 20 miles northwards. How far am i pproximately from my original destination and in what direction ?
Correct Answer
B. 13 miles towards south-west
Explanation
After traveling 20 miles towards the north, 25 miles eastward, 40 miles rightwards, 30 miles towards the left, 12 miles to the left, and finally 20 miles northwards, the total displacement is 25 miles eastward and 7 miles towards the south. Using the Pythagorean theorem, the approximate distance from the original destination is √(25^2 + 7^2) = √(625 + 49) = √674. Therefore, the answer is 13 miles towards south-west.
