Each consonant in the word is moved one step forward to obtain the corresponding letter of the code, while the vowels remain unchanged.

The letters at the third and sixth places are repeated thrice to code BOMBAY as MYMYMY. Similarly, the letters at the third, sixth and ninth places are repeated thrice to code TAMIL NADU as MNUMNUMNU.

The first, second, third and fourth letters of the word are moved two, four, six and eight letters forward respectively to obtain the code.

The first letter of the word is moved to the last position and ‘S’ is placed at the beginning, to form the code.

DISPLAY
SIDPAYL (Step – 1: Swapeed 1–3, and left rotation of 5,6,7 to 6,7,5)
RHCQBZM (Step – 2: -1, -1, -1, +1, +1, +1, +1)

Similarly:
GROUPED
ORGUEDP (Step – 1: Swapeed 1–3, and left rotation of 5,6,7 to 6,7,5)
NQFVFEQ (Step – 2: -1, -1, -1, +1, +1, +1, +1)

Let me know if this sounds correct, or I missed something.

The code for IDEAL is 43586

The code for ‘hot’ is 1.

So, the code of ‘soup’ is 8.

Now the code of ‘is’ is 5.

Hence, we can say that the code of ‘tasty’ is 9.

For any 7 letter word, first swap the first and third letters and also the fifth and seventh letters. Again swap the now sixth and seventh letters. Lastly, swap the fourth and fifth letters. Write the preceding letter for the first three letter and the succeeding letter for the next four. First BONDING is written as NOBGDIN . Then NOB-> MNA and GDIN-> HEOJ leaving MNAHEOJ.

34 has two digits 3 and 4

Multiply these two digits we get get second

number 12

i.e ( 3 × 4 ) = 12

Similarly,

In 59 two digits are 5 and 9

Multiplying these two digits

We get required number

5 × 9 = 45

Odd-positioned letters are coded as the positions forward and even-positioned three positions forward.

Every letter in the code is one letter ahead such as G =R, U=V, N=0 Thus P = Q, E = F, N = 0
