In a certain code language, 'SUMMON' is written as '42' and

Solution

The logic followed here is as follows: To obtain the code, the number of letters in the word is added to the sum of the positional value of all the vowels of the word as per the English Alphabetical series.

For 'SUMMON': Code = {(21 + 15) + 6} = {36 + 6} = 42.

So, 'SUMMON' is written as '42'.

For ‘MORE’: Code = {(15 + 5) + 4} = {20 + 4} = 24

So, 'MORE' is written as '24'.

Similarly, for ‘RURAL’: Code = {(21 + 1) + 5} = {22 + 5} = 27

So, 'RURAL’ will be written as '27'.
