In a certain code language, ‘FEED’ is written as ‘24’, and ‘ACCOUNT’ is written as ‘42’.
How will ‘PIZZA’ be written in that language?

The correct answer is 30.

Let's analyze the logic behind the coding scheme step-by-step.

First, we write down the positions of the letters in the English alphabet:
A = 1, B = 2, C = 3, D = 4, E = 5, F = 6, G = 7, H = 8, I = 9, J = 10, K = 11, L = 12, M = 13, N = 14, O = 15, P = 16, Q = 17, R = 18, S = 19, T = 20, U = 21, V = 22, W = 23, X = 24, Y = 25, Z = 26.

Now, let's look at the first coded word, ‘FEED’:
The letters are F, E, E, and D.
Their alphabetical positions are:
F = 6
E = 5
E = 5
D = 4
Let us calculate the sum of these positions:
Sum = 6 + 5 + 5 + 4 = 20.
To get the code 24 from 20, we can add the number of letters in the word. The word ‘FEED’ has 4 letters:
Code = Sum + Number of letters = 20 + 4 = 24.

Let's verify this pattern with the second word, ‘ACCOUNT’:
The letters and their alphabetical positions are:
A = 1
C = 3
C = 3
O = 15
U = 21
N = 14
T = 20
Let us calculate the sum of these positions:
Sum = 1 + 3 + 3 + 15 + 21 + 14 + 20 = 77.
Let's see if this matches the code 42. Since 77 + 7 (number of letters) = 84, which is not 42, let's explore an alternative logic.

Let's examine the vowels and consonants in each word:

For ‘FEED’ (Code = 24):
Vowels: E, E (2 vowels)
Consonants: F, D (2 consonants)
Let's look at the sum of the positions of the consonants:
F (6) + D (4) = 10.
Let's look at the sum of the positions of the vowels:
E (5) + E (5) = 10.
What if we multiply the number of consonants by the number of letters, or use another combination?
Let's try: (Number of letters) × (Number of consonants) = 4 × 2 = 8. No.
Let's look at the number of vowels and consonants again:
FEED has 4 letters.
ACCOUNT has 7 letters.
PIZZA has 5 letters.

Let's try another simple rule: (Number of letters) × (Something else)?
For FEED: 4 letters. If we multiply 4 by 6, we get 24.
For ACCOUNT: 7 letters. If we multiply 7 by 6, we get 42.
This pattern works perfectly! The code is simply the number of letters in the word multiplied by 6.

Let's check this logic:
1. FEED: 4 letters. $\mathrm{Code}=4\times 6=24$.
2. ACCOUNT: 7 letters. $\mathrm{Code}=7\times 6=42$.

Now, let's apply the same logic to the word ‘PIZZA’:
The word ‘PIZZA’ contains 5 letters (P, I, Z, Z, A).
Using the established rule:
$\mathrm{Code}=\text{Number of letters}\times 6$
$\mathrm{Code}=5\times 6=30$.

Thus, ‘PIZZA’ will be written as 30.
