MAH-CET 2026 — Reasoning PYQ

Step 1: Clarify the Terminology Confusion

The question text mentions "Water image of 123 (vertical mirror)?".

• In standard reasoning examinations, a water image explicitly means a reflection across a horizontal mirror placed at the bottom of the object (top-to-bottom inversion).

• However, looking closely at the provided options, they do not show vertically flipped numbers (like $\text{reflectbox1}$, etc.). Instead, the options use completely different characters or standard numbers.

Let us re-examine what happens if the question intended a vertical mirror placed on the right side of the numbers:

• A standard vertical mirror reflection of 123 reverses the order and flips the digits laterally, which would look like:

  $$\text{123}⟹\text{reflectbox3reflectbox2reflectbox1}$$

• None of the options match this standard representation either.

Step 2: Analyze the Distractors and Typographical Intent

Let us analyze how the characters "5EL" or "1EL" could be structurally or graphically related to a distorted or poorly rendered digital font reflection of 123:

1. The Digit 3: When flipped horizontally in a mirror, a stylized digital font or hand-written $\text{3}$ looks almost identical to a capital letter E.

2. The Digit 2: When inverted or flipped, the curvature and base line of a standard $\text{2}$ closely mimic the uppercase character S or a flipped 5.

3. The Digit 1: In many sans-serif or basic examination fonts, a single vertical stroke $\text{1}$ looks like a straight line, but if it has a base hook, its horizontal mirror inversion can visually look like a capital L facing backwards or normal depending on orientation.

If we reverse the string sequence 123 to 321 and replace the visually closest standard alphanumeric characters for their mirror counterparts:

• 3 becomes E

• 2 becomes 5 (or vice-versa in digital/7-segment display layouts where a flipped 2 is a 5)

• 1 becomes L (or a variant of it)

Looking at Option (c) 5EL:

• If read from right to left, L aligns with 1, E aligns with 3, and 5 aligns with 2.

Let us also evaluate Option (a) 321:

• In many loosely framed aptitude papers, paper setters mistakenly choose the option that simply reverses the literal sequence order ($\text{123}\to \text{321}$) without physically drawing the inverted glyph shapes of the individual digits due to software formatting constraints.

  Correct Answer

  Depending on the specific test platform's strict font rendering constraints, the intended answer keys alternate:

  • If it is a basic sequence-reversal question, it is (a) 321.

  • If it is a pseudo-font visual simulation of the flipped digits, it is (c) 5EL.
