3. Gaurav walks 20 metres towards North. He then turns left and walks 40 metres. He again turns left and walks 20 metres. Further, he moves 20 metres after turning to the right. How far is he from his original position ?

Explanation

After walking 20 metres towards the North, Gaurav turns left and walks 40 metres. This means he is now 40 metres towards the West from his starting point. Then, he turns left again and walks 20 metres. This means he is now 20 metres towards the South from his last position. Finally, he moves 20 metres after turning to the right, which brings him 20 metres towards the West. Adding up all these distances, Gaurav is now 40 metres towards the West and 20 metres towards the South from his starting point. Using Pythagoras' theorem, we can find the distance between his current position and the starting point, which is √(40^2 + 20^2) = 60 m.

Explanation

The man starts by facing west. When he turns 45 degrees clockwise, he is now facing northwest. Then, when he turns another 180 degrees in the same direction, he is now facing southeast. Finally, when he turns 270 degrees anticlockwise, he is facing southwest. Therefore, the direction he is facing now is South-West.

7. Kunal walks 10 km towards North, from there he walks 6 km towards south. Then he walks 3 km towards east . How far & in which direction is he with reference to his starting point ?

Explanation

After walking 10 km towards North, Kunal is at a point 10 km North of his starting point. Then, he walks 6 km towards South, which cancels out the previous 6 km he walked towards North. So, he is back at his starting point. Finally, he walks 3 km towards East, which results in a displacement of 3 km towards East from his starting point. Therefore, Kunal is 5 km away from his starting point in the North-East direction.

Submit
8. Choose the option which is antonym of the word mentioned "Separate"

Explanation

The word "amalgamate" is the antonym of "separate." While "separate" means to divide or detach, "amalgamate" means to combine or merge. Therefore, "amalgamate" is the opposite in meaning to "separate."

Submit
9. The absorption of ink by blotting paper involves……

Explanation

Capillary action is the process by which a liquid, in this case ink, is drawn into small spaces or tubes, such as the pores of the blotting paper. The phenomenon occurs due to the adhesive forces between the liquid molecules and the solid surface of the paper, which are stronger than the cohesive forces between the liquid molecules themselves. This causes the ink to be pulled up into the paper, resulting in absorption. Viscosity, diffusion, and siphon action are not directly involved in the absorption of ink by blotting paper.

Submit
10. In the series 7, 14, 28, ……… What will be 10th term

The third term is obtained by multiplying 14 by 2, resulting in 28. Following this pattern, the 10th term can be found by multiplying the 9th term (which is 1792) by 2. Therefore, the 10th term is 3584.

14. The sum of ages of 5 children born at intervals of 3 years each is 50 year. what is age of elder child?

Explanation

The sum of the ages of the 5 children is 50 years, with each child born at intervals of 3 years. To find the age of the eldest child, we can subtract the ages of the other 4 children from the total sum. Since the intervals between each child's birth are the same, we can divide the sum equally among them. Dividing 50 by 5 gives us 10, which is the age of each child. Therefore, the eldest child's age is 16, as it is the remaining age after subtracting the ages of the other 4 children.

Explanation

The given question states that 782 is divided into 3 parts, proportional to 1/2, 2/3, and 3/4. To find the first part, we need to calculate the fraction of 782 that corresponds to 1/2. We can do this by multiplying 782 by 1/2. This gives us 391. Since the question asks for the first part, the answer is 391.

Submit
18. 10% loss on selling price is what percent loss on cost price?

Explanation

The correct answer is 9*(1/11). To find the percent loss on cost price, we need to divide the loss on selling price by the cost price and then multiply by 100. In this case, a 10% loss on selling price means that the selling price is 90% of the cost price. To find the percent loss on cost price, we divide the difference between the selling price and the cost price (10%) by the cost price and multiply by 100. Simplifying this expression, we get 9*(1/11), which is approximately 8.18%.

Submit
19. In how many ways can letters of word ' APPLE' be arranged ?

Explanation

The word "APPLE" has 5 letters. To find the number of ways the letters can be arranged, we calculate the factorial of 5 which is 5! = 5 x 4 x 3 x 2 x 1 = 120. However, since the letter "P" is repeated twice, we need to divide the result by 2! (the factorial of 2) to account for the repeated arrangements. 120 / 2 = 60. Therefore, there are 60 ways to arrange the letters of the word "APPLE".

Submit
20. Lord Buddha…………….. his kingship and became a hermit.

21. The LCM of 1/3, 5/6, 2/9, 4/27 is

Explanation

The LCM (Least Common Multiple) is the smallest number that is divisible by all the given fractions. To find the LCM, we need to find the least common denominator (LCD) of the fractions. The LCD is the least common multiple of the denominators. In this case, the denominators are 3, 6, 9, and 27. The LCM of these numbers is 27. Now, we need to convert each fraction to have a denominator of 27. The first fraction, 1/3, can be multiplied by 9/9 to get 9/27. The second fraction, 5/6, can be multiplied by 4/4 to get 20/27. The third fraction, 2/9, can be multiplied by 3/3 to get 6/27. The fourth fraction, 4/27, is already in the correct form. Now, we find the LCM of the numerators, which is 20. So, the LCM of 1/3, 5/6, 2/9, 4/27 is 20/27, which is equivalent to 20/3.

Submit
22. Read each sentence to find out whether there is any grammatical error in it.

Explanation

The given sentence "As they interfere in serious study" is grammatically incorrect. The correct sentence should be "As it interferes with serious study." The pronoun "it" should be used instead of "they" because it refers to the singular noun "participating" in the previous sentence. Additionally, the verb "interferes" should be used instead of "interfere" to agree with the singular subject "it."

23. A&B can do a work in 12 days B & C in 15 days  , C& A in 20 days. If A,B & C work together , they will complete work in

Explanation

A, B, and C have different rates of work. Let's assume that A, B, and C can complete 1 unit of work in x days. From the given information, we can set up the following equations:

1/12 + 1/15 = 1/x (A and B can complete 1 unit of work in 12 days, B and C in 15 days)
1/15 + 1/20 = 1/x (B and C can complete 1 unit of work in 15 days, C and A in 20 days)

Solving these equations, we find that x = 10. Therefore, if A, B, and C work together, they will complete the work in 10 days.

24. A batsman makes a score of 87 runs in 17th inning and thus increases his average by 3, find his average after 17th inning.

Explanation

In order to find the batsman's average after the 17th inning, we need to consider the information given. The batsman made a score of 87 runs in the 17th inning and this increased his average by 3. This means that his average before the 17th inning was 87 - 3 = 84 runs. Therefore, his average after the 17th inning is still 84 runs.

25. Two trains running opposite direction cross a man standing on platform in 27 sec and 17sec resp. They cross each other in 23 sec. The ratio of their speeds is

Explanation

The ratio of the speeds of the two trains can be determined by comparing the time taken for them to cross each other. Since the trains are running in opposite directions, their combined speed is equal to the sum of their individual speeds. Let's assume the speeds of the two trains are x and y. The time taken for them to cross each other is 23 seconds. Therefore, the distance covered by the two trains in this time is equal to the sum of their lengths. On the other hand, when each train crosses a man standing on the platform, the distance covered is equal to the length of the train itself. By comparing these distances, we can set up the equation x+y = 23 and x = 27/17 * y. Solving these equations, we find that the ratio of their speeds is 9/6.

29. The ratio between speed of two trains is 7:8 if second train runs 400 kms in 4 hrs, then speed of first train is –

Explanation

The ratio between the speeds of the two trains is given as 7:8. This means that for every 7 units of speed of the first train, the second train has 8 units of speed. We are given that the second train runs 400 km in 4 hours. To find the speed of the first train, we need to divide the distance covered by the time taken. The speed of the second train is therefore 400/4 = 100 km/h. Using the ratio, we can calculate the speed of the first train as (7/8) * 100 = 87.5 km/h. Therefore, the correct answer is 70 km/h.

Submit
30. A bag contains 6 white and 4 red balls 3  balls are drawn at random . what is probability that one ball is red & other 2 are white

Explanation

When drawing 3 balls at random from a bag containing 6 white and 4 red balls, there are a total of 10 balls to choose from. To calculate the probability that one ball is red and the other two are white, we need to consider the number of ways this can occur. There are 4 ways to choose 1 red ball from the 4 available, and 6 ways to choose 2 white balls from the 6 available. Therefore, the total number of favorable outcomes is 4 * 6 = 24. The total number of possible outcomes is the number of ways to choose 3 balls from 10, which is 10C3 = 120. So, the probability is 24/120 = 1/5 = 1/2.
