Dates on which Tuesday fall are 3,10,17, and 24

Hence, the 27th day of the month will be (Tuesday + 3 days=)Friday

Required day of the month = Friday - 4 = Monday

Answer : 5

Explanation : Given that, For each letter in the word (FLIES) there is a code written and also that code is denoted by either 1 , 2, 3, 4 or 5 

Apply the below code, It exactly matches the Given Condition

Letters at odd- numbered places shift three positions backward and letters at even-numbered places shift two positions forward as in English alphabet.

Here, Odd- Numbered Places F, I , S shift three positions backward in English Alphabet.

Even- Numbered Places L, E shift two positions forward in English Alphabet.

Therefore, exact code for the underline letter (F) is C.

So the Answer is 5.

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. 

A person will stand on the floor and floor is called roof. So, a person will stand on the roof

ja ke mo pe    =>  at a frog's leap          --------(i)

mo la ki so     =>  take a leapahead       --------(ii)

re bo na ja     =>  insects are frog's diet  --------(iii)

From (i) and (ii),   a leap  =>  ki mo       --------(iv)

From (i) and (iii),  frog's   =>   ja           ---------(v)

From (i), (iv) and (v),  'at' => pe

Letters of the word PREMONITION are coded as follows:

Letters :  P    R    E    M    O    N    I    T    I    O    N

Code:        6    8    5    3    0    4    9    2    9    0    4

See the code below Is and Ns. Codes for I and N are 9 and 4 respectively. This indicates that the digits below each letters represent its code. Therefore, code for the word MONITOR is 3049208

Following table depicts the code of used letters in the two given words: 

Letters     S     T     A     R     O     E

Code          5     $     *     2     3     @

Therefore, OATS => 3*$5

Look at the following table which shows the letters and their respective codes :

Letter     A     B     D     E     G     I     M     U     

Code       5     8     3     2     4     1     7     9

Therefore, the code for IMAGE is 17542
