From the above arrangements, M is to the immediate right of D.

Father's wife — Mother;  Mother's daughter — Sister;  Sister's younger brother — My younger brother. 

So, the boy is Deepak's brother. 

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.

121 is the only perfect square number in the group.

The rupee is the currency of India. Similarly, Yen is the currency of Japan.

Here it follows

426-153=2 and  3819-2010 =0

In the same way  399-93=1

For convenience , we assign numbers to each word :

allow  children  to  play  on  the  ground

   1         2      3    4      5    6       7

It has been coded as : 

play  allow  on  children  the  to  ground

  4       1     5        2       6    3      7

------------------------------------------------------------------------

Hence the given code is :

the  do  open  not  electric  touch  wires

 4     1      5     2       6         3       7

Now arranging them as 1 2 3 4 5 6 7, we have "do not touch the open electric wires'.

Hence, option (3) is correct answer.
