If we count letters till the end of the alphabet including that letter in reverse order then
Here the values are nothing but the values corresponding to the alphabets when taken in a reverse order,i.e,A=26 ,B=25...,Z=1
G = 20 and O = 12 totaling 32
S = 8, H = 19 and E = 22 totaling 49

So
SOME = 8 + 12 + 14 + 22 = 56.

plan is given in first step. Total count of letters is 4 and last letter is N and ?p? is coded as & so Final answer will be-  &N4

We have to find 'translate' code. As we can see that this word is not given in any steps but as we know the idea of that so we can solve it.

Step I: first we will count the letters of that word that is 9, then we put digit 9 at the right end.

Step II: we will put the last letter of that word then it will like- E9

Step III: at the last step ?t? is coded for ?@?(first letter of each word is coded by a specific symbol like here ?t? is coded for ?@?. We can find the first coded symbol by looking at the other given words.

Answer will be - @E9

FRIEND : FPIBNZ

Follows a pattern that,

F - F

R- second letter to left of R i.e, P

I - I

E - Third letter to left of E i.e, B

N - N

D - Fourth letter to left of D i.e, Z

Similarly, for PATRON 

P - P

A -  second letter to left of A i.e, Y

T - T

R - Third letter to left of R i.e, O

O - O

N - Fourth letter to left of N i.e, J

PATRON : PYTOOJ

Therefore, FRIEND : FPIBNZ :: PATRON : PYTOOJ

The word if formed into pairs of letters and the letters in each pair are reversed

Here HAT is coded as jcv

=> Leaving a letter in between i.e, after H leave i write j in small letters

In the same way, A => c, T => v

Similarly for GUN => iwp 

If each consecutive letter in "happiness" relates to the consecutive numbers in 517768399, then H=5, A=1, P=7, I=6, N=8, E=3 and S=9.

Using the numbers that relate to the letters in 'senipah', you will arrive at

SENIPAH = 9386715.

Hence, Happiness is to 517768399 as senipah is to 9386715.

Movement of letters  is +1, +2, +3, +4, +5

Therefore, SMILE => TOLPJ

We can find the code for 'food' form the first and second statements.
Now, to find the code for 'hot',
we need to the code for 'bring' which cannot be determined from the given information.

In the first and third statements, the common code word is 'peru' and the common word is 'fine'.

So, 'peru' means 'fine'.

From the given data,
how many goals scored = 5397....(1)
many more matches = 982.....(2)
he scored five = 163.....(3)
from (1)&(2), many = 9 ....(4)
from (1)&(3), scored = 3 ....(5)
Using (4)&(5)in(1), we get goals = 5 or 7.
