In a certain code language, ‘EXPLAIN’ is coded as ‘15912141624’. How will ‘SACRED’ be coded in that language?

Let's look at the positional values of letters in 'EXPLAIN':
E = 5, X = 24, P = 16, L = 12, A = 1, I = 9, N = 14

Now let's sort these positional numbers in ascending order:
1, 5, 9, 12, 14, 16, 24

When combined together, they form the code string: 15912141624.
Thus, the logic is to take the alphabetical positional values of all letters in the word and arrange them in ascending numerical order.

Let's apply this to 'SACRED':

S = 19

A = 1

C = 3

R = 18

E = 5

D = 4

Arranging these values (1, 19, 3, 18, 5, 4) in ascending order:
1, 3, 4, 5, 18, 19

Concatenating them gives: 13451819
