Writing 421579368 in ascending order gives 123456789, and comparing the two, three pairs of digits keep the same number of digits between them in both arrangements. So the answer is three.

Answer: A

Initialy from left 7th = kumar
from right 9th = pawan
Interchange kumar = 11th from left, from right kumar = 9th;
11+8 = 19;
8 is 1,2,3,4,5,6,7(pawan),8,9,10,11(kumar),12,13,14,15,16,17,18,19;
simply count the 9th place from right we will get total as 19.

Palak stands seven places to the right of Shweta’s 27th, so she is 34th from the left. In a row of 74 that makes her \[ 74 - 34 + 1 = \mathbf{41} \text{st from the right} \]

Answer: A

Here the given numbers are 

567  284  696  865  738

When 1 is added to the last digit of each of the above numbers, it becomes as follows :

568  285  697  866  739

After reversing the order of digits , we get

865  582  796  668  937

Now , when the numbers are arranged in ascending order their order becomes as follows:

582  668  796  865  937

Hence , the fourth number is 865 (a number formed by 567). Therefore option(1) is correct answer.
