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.

The table given below shows the marks obtained by four students in 4 different subjects. Maximum marks for each subject is 175. What is the aggregate percentage of marks obtained by Gunja in all the four subjects?

(a)58
(b)61
(c)67
(d)71

Answer

Why

Correct — B. Read Gunja's row only, then set her total against the total possible.

Marks: 112 + 119 + 99 + 97
112 + 119 = 231
231 + 99 = 330
330 + 97 = 427

Maximum = 4 subjects × 175 = 700

427 ⁄ 700 × 100 = 61% → option (b)

Why the others are wrong

(a)
58 — 58 needs a total of 406 marks. Gunja's four entries add to 427, and no row in the table totals 406 either — this is a near-miss decoy, not another student's aggregate.
(c)
67 — 67 would require 469 out of 700. It survives only on an inflated addition of Gunja's row, so recheck 112 + 119 + 99 + 97, which lands on 427.
(d)
71 — 71 is what 427 out of 600 comes to, rounded — the figure you reach by taking the maximum as 150 a subject. The stem states 175, so the total possible is 700 and the aggregate is exactly 61%.

Concept

An aggregate percentage is total scored ⁄ total maximum × 100, and the denominator has to count every subject in the row.

The table's own numbers set the trap: marks in the 90s and 100s look like percentages, but each subject is out of 175. Gunja's 112 in Mathematics is 64%, not 112%.

Aggregate percentage is not generally the average of the four subject percentages. It equals that average here only because all four subjects share the same maximum.

Only Gunja's row matters — the rest of the table is there to slow the read. Losing track of which row you are on is a likelier error than mis-adding four two-digit and three-digit numbers.

Key facts

Gunja scored 112, 119, 99 and 97, which total 427.
The maximum is 175 per subject, so four subjects give 700.
427 out of 700 is exactly 61%.

Study next

Reading a two-tier table header where one column spans several sub-columnsComparing two students by percentage when their maximums differIdentifying the subject in which a given student's percentage is highest

Common traps

Treating the marks as percentages because they sit near 100.
Using 100 or 150 as the per-subject maximum instead of 175.
Adding down a subject column instead of across the Gunja row.

SSC pairs a small table with a one-step arithmetic ask, so the reading is the difficulty and not the sum — this same 19 Sep 2024, 09:00 paper asks for a plain average of six subject marks at Quant Q.12.
