Text as printed on a candidate's response sheet for this shift; answer per SSC's tentative key as marked on that sheet. Solution last reviewed 10 September 2026.

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.

Answer

Why

Correct — C. MN is drawn as a vertical line to the right of the string, so the image is a left-to-right flip.

Rule: the reading order reverses — h r 4 9 j k z becomes z k j 9 4 r h — and every character is also flipped about its own vertical axis.

Option (c) does both. Its leading z has the diagonal running from top-left to bottom-right, the k carries its stem on the right of the arms, the j's tail curls to the right, and the 9 keeps its loop on top with the stem now dropping on its left.

Why the others are wrong

(a)
The order and the letters are right, but the 4 and the 9 are turned upside-down instead of sideways — the 9 reads as a 6, which no vertical mirror can produce.
(b)
The z at the left end is not flipped: its diagonal still falls from top-right to bottom-left, exactly as in the printed string.
(d)
The k and the j keep their original orientation — the k's stem stays to the left of its arms and the j's tail still hooks leftwards.

Concept

A mirror on a vertical line does one thing: it swaps left and right and leaves top and bottom alone.

So a line of text reverses its reading order, and each glyph is flipped about its own vertical axis. Heights, ascenders above the line and tails below it all stay where they were.

That gives a two-test method. Check the order first — the last character of the original has to be leftmost — then check one character with a loud left-right asymmetry, such as the k or the j.

The options are pictures, so nothing can be compared as text. Check the digits separately from the letters: a 9 turned upside-down reads as a 6 and is the easiest error to walk past.

Key facts

A vertical mirror reverses left and right while preserving top and bottom.
The printed string reads h, r, 4, 9, j, k, z, so its mirror image must begin with z.
A 9 flipped sideways keeps its loop at the top, while a 9 turned upside-down reads as a 6.

Common traps

Reversing the order of the characters but forgetting to flip each one.
Treating digits as symmetric and leaving them untouched.
Confusing a vertical mirror with a water image, which flips top and bottom instead.
