17:289::27:?
Correct Answer
B. 729
Explanation
The pattern in the given sequence is that the first number is multiplied by 17 and the second number is multiplied by 9 to get the next number. In the sequence 17:289::27:?, 17 is multiplied by 17 to get 289. Following the same pattern, 27 should be multiplied by 9 to get the missing number. Therefore, the missing number is 729.

If p means xy means –x means +z means / then the value of (10 p 4) x (4y4) p 6=?
Correct Answer
B. 40
Explanation
In the given expression, "p" means multiplication, "xy" means subtraction, "–x" means addition, and "+z" means division. So, we can rewrite the expression as (10 * 4) - (4 + 4) * 6. Simplifying further, we get (40 - 8) * 6 = 32 * 6 = 192. Therefore, the correct answer is 192.

Starting from his house. Nithin travels a distance of 8 m towards the north, he then turns left and travels a distance of 6 m, then travels 5 m South and finally he travels 6 m towards the west to reach his office. What is the approximate shortest distance between his house and the office.
Correct Answer
A. 12.5
Explanation
Nithin first travels 8 m towards the north, then turns left and travels 6 m, which means he is now facing west. He then travels 5 m towards the south, which means he is now 3 m south of his starting position. Finally, he travels 6 m towards the west. We can visualize this as a right-angled triangle, with the 8 m and 3 m sides representing the distances traveled towards the north and south respectively, and the hypotenuse representing the shortest distance between his house and office. Using the Pythagorean theorem, we can calculate the length of the hypotenuse as approximately 8.5 m. Therefore, the approximate shortest distance between his house and office is 12.5 m.

In certain code language, East is called North-east, South-east is called East, South is called South-east, South-west is called south and so on. A man starts travelling as per the original directions and travels a distance of 7 km towards North-east then turns to an angle of 90 degrees clockwise and travels 24 km in that direction. How far and in which direction is he now from the starting point in that language?
Correct Answer
C. 25 km, East
Explanation
The man initially travels 7 km towards North-east. Then, he turns 90 degrees clockwise, which means he is now facing East. He travels 24 km in that direction. Therefore, he is now 25 km away from the starting point in the East direction.

512 , 256/3 , 128/9 , 64/27 , 32/81 , ____
Correct Answer
C. 16/243
Explanation
The pattern in the given sequence is that each term is obtained by dividing the previous term by 3. Starting with 512, we divide it by 3 to get 256/3. Then, we divide 256/3 by 3 to get 128/9, and so on. Continuing this pattern, we divide 32/81 by 3 to get 16/243. Therefore, the missing term in the sequence is 16/243.

16, 8, 8, 12, 24, 60, 180, _____
Correct Answer
B. 630
Explanation
The pattern in the given sequence is as follows:
- The first number is multiplied by 0.5 to get the second number (16 * 0.5 = 8).
- The second number is repeated twice (8, 8).
- The third number is obtained by adding the two previous numbers (8 + 8 = 16).
- The fourth number is obtained by multiplying the third number by 1.5 (16 * 1.5 = 24).
- The fifth number is obtained by multiplying the fourth number by 2.5 (24 * 2.5 = 60).
- The sixth number is obtained by multiplying the fifth number by 3 (60 * 3 = 180).
- The seventh number is obtained by multiplying the sixth number by 3.5 (180 * 3.5 = 630).
Therefore, the missing number in the sequence is 630.

In the number 94621538, if the 1st digit interchanges its place with the 8th digit, 2nd digit interchanges its place the with 7th digit and so on, then which number is second to left of the digit which is 4th from the right?
Correct Answer
B. 5
Explanation
To find the number second to the left of the digit which is 4th from the right, we need to rearrange the given number according to the given conditions. After rearranging the number, we get 84621593. The digit which is 4th from the right is 1. The number second to the left of 1 is 5. Therefore, the correct answer is 5.
