If BALLOON rightarrow N1515LL1B, find MONDAY

Last updated Aug 8, 2026
Correct Answer: Option A — Y1DN15M
To find the code for MONDAY, let's break down the logic used for the word BALLOON.

Step 1: Reverse the Order
The first rule is to write the word backward.

BALLOON reversed becomes NOOLLAB.

Step 2: Replace Vowels with Alphabet Positions
Identify the vowels (A, E, I, O, U) and replace them with their numerical position in the alphabet:

A is the 1st letter.

O is the 15th letter.

Applying this to NOOLLAB:

N stays N.

O becomes 15.

O becomes 15.

L stays L.

L stays L.

A becomes 1.

B stays B.

Result: N1515LL1B.

Applying the Logic to MONDAY
Reverse the Letters:
MONDAY reversed is YADNOM.

Replace the Vowels:

A is replaced by 1.

O is replaced by 15.

Final Code:

Y stays Y.

A becomes 1.

D stays D.

N stays N.

O becomes 15.

M stays M.

The final result is Y1DN15M.
