2 4 5 1 4 7 9 6 3 8

After arranging the first half and the second half of the digits of given number in ascending order, we get new number as:

1 2 4 4 5 3 6 7 8 9

Now,

2 | 4 | 5 | 1 | 4 | 7 | 9 | 6 | 3 | 8 |

1 | 2 | 4 | 4 | 5 | 3 | 6 | 7 | 8 | 9 |

Comparing both the numbers, we can say that there is no number whose position remains unchanged.

Hence, the correct answer is option C.

C

Using the given information we can create a following figure:

Here the total number of persons in the queue = (*29 + 19 - 1)

= 47

*Note: 29 is derived by adding Ram's position from left end of the row (24) and his position with respect to Priya (5).*

Hence, the correct answer is option C.

Here the total number of persons in the queue = (*29 + 19 - 1)

= 47

Hence, the correct answer is option C.

D

Here, we know that Vikram was ninth from the left while Hariom was thirteenth from the left. So, we can say that there were 3 persons between Vikram and Hariom.

And, we also know that Hariom was exactly in the middle of Vikram and Janhvi so the number of persons between Hariom and Janhvi will also be 3.

At this point, using the given information we can create a following figure:

Now, total number of people in the queue = (8 + Vikram + 3 + Hariom + 3 + Janhvi + 7)

= (8 + 1 + 3 + 1 + 3 + 1 + 7) = 24

Thus, the total number of people in the queue was 24.

Hence, the correct answer is option D.

And, we also know that Hariom was exactly in the middle of Vikram and Janhvi so the number of persons between Hariom and Janhvi will also be 3.

At this point, using the given information we can create a following figure:

Now, total number of people in the queue = (8 + Vikram + 3 + Hariom + 3 + Janhvi + 7)

= (8 + 1 + 3 + 1 + 3 + 1 + 7) = 24

Thus, the total number of people in the queue was 24.

Hence, the correct answer is option D.

B

Adding all the persons in the above image, we get:

8 + 1(Trisha) + 5 + 1(Tanya) + 5 + 1(Tina) + 11 = 32

Thus there are 32 cadets in the row.

Hence option B is the correct answer.

5

B

From the given image it is clear that Ayesha is 12th from the right end.

Position of Ayesha from right end = 7 + 1(Anisha) + 1 + 1(Ariva) +1 + 1 = 12

Hence option B is the correct answer.

Position of Ayesha from right end = 7 + 1(Anisha) + 1 + 1(Ariva) +1 + 1 = 12

Hence option B is the correct answer.
