Where this paper and its answers come from

SSC does not publish CGL question papers or a public answer key. The questions and options here are reproduced as printed on a candidate's own response sheet for this shift — the Commission's text, unchanged. Each answer is SSC's tentative key as marked on that sheet; SSC allowed challenges to it and never publishes a final key. The solutions are written by UnlockIAS.

Select the correct mirror image of the given figure when the mirror is placed at MN as shown below.

Answer

Why

Correct — B. Rule: a mirror at MN, the vertical line to the right of the figure, reverses the left-to-right order and flips each character sideways. Nothing moves up or down.

The figure reads M a 3 7 c F, so the reflection reads F c 7 3 a M from left to right, every glyph laterally inverted.

M is symmetric about a vertical axis, so it returns as an ordinary M. The a becomes a reversed a, the 3 a backwards 3, the 7 a backwards 7, the c an arc opening to the left, and the F a backwards F.

Option (b) is the one that does all of it: order reversed, every glyph flipped sideways, the final M upright.

Why the others are wrong

(a)
Option (a) is wrong twice over. It puts a reversed e where the figure has an a, and its F is upside down — arms at the middle and bottom — where a vertical mirror keeps them at the top and middle.
(c)
Option (c) turns the final M upside down into a W. That is what a mirror lying along a horizontal line does, and MN is vertical, so top and bottom must stay where they are.
(d)
In option (d) the numerals still read 37 in their original left-to-right order, and neither digit is inverted. A vertical mirror gives a backwards 7 followed by a backwards 3.

Concept

A mirror on a vertical line does exactly two things. It reverses the order of the characters, and it flips each character left to right.

Test an option on the cheapest evidence first, which is the order. If the last character of the figure is not the first character of the option, that option is gone before you inspect a single glyph.

Then check the glyphs that give themselves away. A, H, I, M, O, T, U, V, W, X, Y, 0 and 8 are unchanged by a vertical mirror, so if one of those looks different, the option flipped the wrong way.

Option (c) fails on a single glyph and option (a) on two, so reading the string as a whole is not enough. Check the last glyph and the numerals separately.

Key facts

A vertical mirror reverses character order and flips each character sideways, leaving top and bottom untouched.
M is symmetric about a vertical axis, so it looks the same in a vertical mirror.
The figure reads M a 3 7 c F, so its vertical mirror reads F c 7 3 a M with each glyph inverted.

Common traps

Reversing the order but leaving the glyphs unflipped, which is a rotation and not a reflection.
Flipping top to bottom, which turns M into W and belongs to a water-image question.
Accepting an option because the sequence reads right, without checking each glyph.

The same MN stem, word for word, is asked on 12 Sep 2024, 12:30, Reasoning Q.6, so the reverse-then-flip routine is worth drilling until it needs no thought.
