Coding and Decoding Questions

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.

In the first and second statements, the common code digit is '2' and the common word is 'carpet'.

So, '2' means 'carpet'.

In the second and third statements, the common code digit is '6' and the common word is 'one'.

So, '6' means 'one'.
Therefore, in the second statement, '5' means 'dust'.

The first three letters are coded as same positioned letters from the right end of the alphabet. So are the seventh to tenth letters. The fourth , fifth and sixth letters move one, two and three positions forward respectively in the alphabet. So, do the last three letters. Thus,

CONCENTRATION => XLMDGQGIZGJQQ

Now reverse this and we get QQJGZIGQGDMLX

A person will stand on the 'floor' and 'floor' is called 'roof'.

So, a person will stand on the 'roof'.

According to question: S=U, T=V, U=W, D=F, E=G, N=P, T=V

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

Therefore, SMILE => TOLPJ

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.
