SSC CGL 2025 Tier-I · 16 September 2025, Shift 2 · 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.

10 friends went for dinner and planned to split Rs. 200 equally. 2 didn’t pay. How much did each of the rest pay?

(a)Rs. 25
(b)Rs. 20
(c)Rs. 22
(d)Rs. 28

Answer

Why

Correct — A.
Rule: the whole bill still has to be paid, so divide it among those who pay.

Payers: 10 − 2 = 8
Each pays: 200 ÷ 8 = Rs. 25 → option (a).

Check: 8 × 25 = 200, the full bill.

Why the others are wrong

(b)
Rs. 20 — Rs. 20 is the planned share, 200 ÷ 10. Eight people paying Rs. 20 each cover only Rs. 160 of the Rs. 200 bill.
(c)
Rs. 22 — Rs. 22 from eight people makes Rs. 176, which leaves Rs. 24 of the bill unpaid.
(d)
Rs. 28 — Rs. 28 from eight people makes Rs. 224, which is Rs. 24 more than the bill.

Concept

Sharing problems turn on what stays fixed. Here the bill, Rs. 200, stays fixed while the number of payers falls from 10 to 8.

When a fixed total is split among fewer people, each share rises. The two non-payers' Rs. 40 is spread over eight people, Rs. 5 each, so Rs. 20 becomes Rs. 25.

The stem does not say in words that the eight covered the whole bill. Rs. 20 answers the other reading, that each paid only the planned share; the key takes the full-bill reading.

Key facts

Share per payer = total ÷ number of payers.
The non-payers' Rs. 40, spread over 8 payers, adds Rs. 5 to each share.
8 × Rs. 25 = Rs. 200.

Common traps

Stopping at the planned share, Rs. 20, without spreading the unpaid part
Spreading the unpaid Rs. 40 over all 10 friends instead of the 8 who pay

A fixed total is split among fewer people than planned: find the number who pay first, then divide.
