SSC CGL 2025 Tier-I · 23 September 2025, Shift 1 · General Intelligence and Reasoning · Question 25 of 100

We transcribed this text from the pictures on a candidate's response sheet for this shift; the answer is the key SSC colour-marked on that sheet. Solution last reviewed 13 September 2026.

Where this paper and its answers come from

SSC does not publish CGL question papers or a public answer key. From 2025 the candidate response sheet prints every question and option as a picture, so the text here is transcribed from those pictures for this shift and checked against them independently; where the layout carries meaning, the picture is shown as well. Each answer is the key SSC colour-marked on that sheet. SSC released a tentative key for challenge and later its final one, both only to candidates behind a login, and the sheet does not say which of the two it carries. The solutions are written by UnlockIAS.

If in a code language, 'CAR' is written as 'FDW', then 'BAT' is written as?

(a)EDY
(b)GEX
(c)FCX
(d)FBY

Answer

Why

Correct — A.
Rule: read the shift at each position: +3, +3, +5.

C (3) → F (6): +3
A (1) → D (4): +3
R (18) → W (23): +5

B (2) + 3 = E (5)
A (1) + 3 = D (4)
T (20) + 5 = Y (25)

BAT → EDY → option (a).

Why the others are wrong

(b)
GEX — GEX moves B five places to G. The first position moves +3, as C → F shows, so B becomes E.
(c)
FCX — FCX moves B four places and A two. The pair CAR → FDW fixes +3 for both of the first two letters: E and D.
(d)
FBY — FBY gets the last letter right (T + 5 = Y) but moves A only one place. The second position moves +3, so A becomes D.

Concept

A code given by a single pair can shift each position by a different amount, so work out the shift letter by letter before applying it. Here the first two letters move +3 and the third moves +5.

Assuming one shift for the whole word would give B + 3, A + 3, T + 3 = EDW, which is not among the options. That is the signal to look again at the third letter.

The stem gives one pair, so the +3, +3, +5 reading is what it supports. Checked against that reading, EDY fits at all three positions and each of the other options fails at least one.

Key facts

C → F and A → D are shifts of +3, and R → W is a shift of +5.
B + 3 = E, A + 3 = D, T + 5 = Y.
A uniform +3 would give EDW, which is not offered.

Common traps

Checking only the first letter's shift and applying +3 throughout.
Taking FBY because its last letter, Y, is right, when its first two letters move +4 and +1.

A uniform +3 code is set at 24 Sep 2025, 12:30, Reasoning Q.25 (PEARL → SHDUO, so STONE → VWRQH), where every letter moves the same three places.
