SSC Selection Post Mock Test 2027: Free Phase 15 Series PDF

AMBER CALLOUT BOX: Be cautious of false information spread by competitors.

• (1) The myth regarding the 60-minute open timer: many simulated examination platforms still display the SSC Selection Post as having a flexible 60-minute open timer, enabling you to complete the General Awareness section in 5 minutes and then spend 30 minutes on Maths. However, the actual new rule for the SSC CBT (introduced in Phase XIV in 2026) is different. The 100-question, 200-mark CBT is now divided into four fixed 15-minute sections: Reasoning is given 15 minutes, General Awareness 15 minutes, Quantitative Aptitude 15 minutes, and English 15 minutes. When the 15 minutes for a section have ended, that section locks automatically and you are not allowed to switch to another section or carry any unused time over.
• (2) Incorrect Tables of the Minimum Qualifying Marks: A major examination website published a wrong table stating that "UR = 35% (60 marks) and OBC/EWS = 30% (70 marks)". They made mistakes in both the official percentages and in simple mathematics. The actually verified official SSC minimum qualifying marks out of 200 are UR = 30% (60 Marks), OBC/EWS = 25% (50 Marks), and All Other Categories = 20% (40 Marks).
• (3) False Descriptive Test Claims and Mixed Mock Traps: There is absolutely no Descriptive Tier-2 paper in the SSC Selection Post. Selection is based entirely on a single 200-mark CBT stage, plus a Post-Specific Qualifying Skill Test when required, followed by Document Scrutiny. Practicing with a single mixed mock pool is entirely ineffective. The syllabus depth for Maths and English differs greatly among the Matriculation (10th), Higher Secondary (10+2), and Graduation levels.

Worked Student Example 1: A candidate finishes General Awareness in 8 minutes. They look at the locked screen for 7 minutes and get bored. They blindly guess on 8 questions they don't know. Those 8 wrong guesses take away 4.00 full marks, ruining their chance of getting a post with a high cutoff.

Worked Student Example 2: A candidate applies 50:50 elimination to 10 English questions. They get 6 correct and 4 wrong. The calculation is (6 x 2.00) - (4 x 0.50) = 12.00 - 2.00 = +10.00 net marks. Smart guessing wins the game.

Q1. (Matric Level, Arithmetic) एक दुकानदार किसी वस्तु पर 20% की छूट देता है, और फिर भी 25% का लाभ कमाता है। यदि वस्तु का क्रय मूल्य ₹400 है, तो अंकित मूल्य ज्ञात कीजिए।
A shopkeeper gives a discount of 20% on an item and yet manages to make a profit of 25%. If the cost price of the article is ₹400, what is its marked price?
A. ₹550
B. ₹600
C. ₹625 [Correct]
D. ₹650

Option (Correct): C. ₹625 [Correct] -> Reason: Since the profit is 25%, the selling price (SP) is 125% of the cost price and therefore equals 1.25 × 400 = 500. The discount is 20%, which means that the selling price is 80% of the marked price (MP). Hence, 80% of MP is 500. MP = (500 × 100) / 80 = ₹625.
Option (Incorrect): A. ₹550 -> Reason: Due to incorrect mapping of the percentages.
Option (Incorrect): B. ₹600 -> Reason: Assumes a simple addition without carrying out the correct discount ratio calculation.
Option (Incorrect): D. ₹650 -> Reason: Made a mistake in the final division.
Hint: Always remember that SP = CP × (100 + Profit%)/100 = MP × (100 - Discount%)/100.

Q2. (10+2 Level - Advance Maths) If $x + \frac{1}{x} = 5$, then what is the value of $x^3 + \frac{1}{x^3}$?
A. 110 [Correct]
B. 115
C. 120
D. 125

The correct option is A. 110 [Correct] because the standard algebraic identity says that when $x + \frac{1}{x} = k$, then $x^3 + \frac{1}{x^3} = k^3 - 3k$. In this case, $k = 5$, so $5^3 - 3(5) = 125 - 15 = 110$.
Option B. 115 is incorrect because of an arithmetic error when subtracting.
Option C. 120 is incorrect because of an erroneous subtraction value.
Option D. 125 is incorrect because it simply calculates $k^3$ and fails to subtract $3k$.
Hint: In algebra use the direct shortcut $k^3 - 3k$.

Q3. (Graduate Level - Geometry) In a right-angled triangle, the length of the hypotenuse is 13 cm and one of the base sides is 5 cm. What will be the area of the circumcircle (circumcircle) of this triangle? ($\pi = 3.14$)
A. 132.66 sq cm [Correct]
B. 120.50 sq cm
C. 140.25 sq cm
D. 150.00 sq cm

The correct option is A. 132.66 sq cm [Correct] because in a right-angled triangle the circumcentre is exactly at the midpoint of the hypotenuse. Thus, the circumradius R is equal to the hypotenuse divided by 2, which is 13 divided by 2 = 6.5 cm. The area is equal to $\pi R^2 = 3.14 \times (6.5)^2 = 3.14 \times 42.25 = 132.665$ sq cm.
The options B, C and D are incorrect because they do not realise that the hypotenuse serves as the diameter of the circumcircle.
Hint: In a right-angled triangle the hypotenuse is the diameter of the circumcircle.

Q4. (Number Series) Find the next term in the following series: 7, 15, 31, 63, 127, ?
A. 254
B. 255 [Correct]
C. 256
D. 257

Option (Correct): B. 255 [Correct] — Reason: The rule is to multiply the previous number by 2 and then add 1. (7 × 2 + 1 = 15; 15 × 2 + 1 = 31; 63 × 2 + 1 = 127). The next term is therefore 127 × 2 + 1 = 255.
Option (Incorrect): A. 254 — Reason: It omits the +1 step.
Option (Incorrect): C. 256 — Reason: The arithmetic logic is wrong.
Option (Incorrect): D. 257 — Reason: It adds too much after multiplying.
Hint: Each number is becoming double and then one is added ($\times 2 + 1$).

Q5. (Coding-Decoding) If in a certain coded language 'ROSE' is written as 'TQUG', then how will 'BLUE' be written?
A. DMWG
B. CNVF
C. DNWG [Correct]
D. DNVF

The correct option is C. DNWG [Correct] because each letter is shifted forward by two positions: R(+2)=T, O(+2)=Q, S(+2)=U, E(+2)=G. When this rule is applied to BLUE, we get B(+2)=D, L(+2)=N, U(+2)=W, E(+2)=G, resulting in DNWG.
The incorrect options are A, B, and D because they show incorrect letter shifts.
Hint: In the English alphabet each letter is advancing by two places (+2).

Q6. (Syllogism) Statements: All cats are dogs. Some dogs are rats. Conclusions: I. Some rats are cats. II. Some dogs are cats.
A. Only conclusion I follows
B. Only conclusion II follows [Correct]
C. Both conclusions follow
D. None of the conclusions follows

Option (Correct): B. Only conclusion II follows [Correct] -> Reason: If you draw a Venn diagram, all Cats will be inside Dogs. Rats overlap with Dogs but do not necessarily touch Cats. Therefore Conclusion I is uncertain. Since all Cats are Dogs, it is definitely true that some Dogs are Cats (Conclusion II).
Option (Incorrect): A, C, D -> Reason: This fails the basic logic of subset inclusion.
Hint: Draw a Venn diagram and remember that if two circles do not touch each other, a conclusion about them cannot be certain.

Q7. (Error Spotting) Identify the segment that contains a grammatical error: "Neither the manager nor the employees was aware of the new policy."
A. Neither the manager
B. nor the employees
C. was aware of [Correct]
D. the new policy

Option (Correct): C. was aware of [Correct] -> Reason: When two subjects are joined by "neither... nor", the verb must agree with the subject that is closest to it. Since "employees" is plural, the verb should be "were aware", not "was aware".
Option (Incorrect): A, B, D -> Reason: These segments are grammatically correct.
Hint: In sentences with "neither... nor", the verb always agrees with the nearest subject.

Q8. (Active/Passive Voice) Choose the correct passive voice: "The mechanic is repairing the car."
A. The car is repaired by the mechanic.
B. The car was being repaired by the mechanic.
C. The car is being repaired by the mechanic. [Correct]
D. The car has been repaired by the mechanic.

Option (Correct): C. The car is being repaired by the mechanic. [Correct] -> Reason: The active sentence is in the Present Continuous tense. In the passive voice, the structure is is/are/am + being + V3. Therefore, "is being repaired" is correct.
Option (Incorrect): A. The car is repaired -> Reason: This is simple present passive.
Option (Incorrect): B. The car was being repaired -> Reason: This is past continuous passive.
Option (Incorrect): D. The car has been repaired -> Reason: This is present perfect passive.
Hint: When changing Present Continuous into passive, the word 'being' must always be used.

Q9. (Static GK) Which article of the Indian Constitution provides for a 'Uniform Civil Code'?
A. Article 40
B. Article 44 [Correct]
C. Article 48
D. Article 50

Option (Correct): B. Article 44 [Correct] — Reason: Article 44, under the Directive Principles of State Policy, directs the State to secure a Uniform Civil Code for citizens throughout India.
Option (Incorrect): A. Article 40 — Reason: It concerns the organization of village panchayats.
Option (Incorrect): C. Article 48 — Reason: It relates to agriculture and animal husbandry.
Option (Incorrect): D. Article 50 — Reason: It relates to the separation of judiciary from executive.
Hint: This article is found in part IV of the State Policy Directive Principles.

Q10. (Science) What is the largest gland in the human body?
A. यकृत (Liver) [Correct]
B. अग्न्याशय (Pancreas)
C. थायराइड (Thyroid)
D. पीयूष ग्रंथि (Pituitary)

The correct option is A. यकृत (Liver) [Correct] because the liver is the largest solid internal organ and the largest gland in the human body, being essential for metabolism and detoxification.
Option B. Pancreas is incorrect because it is the second largest gland.
Option C. Thyroid is incorrect since it is the largest endocrine gland but not the largest overall.
Option D. Pituitary is incorrect because it is a very small master gland situated at the base of the brain.
Hint: This gland produces bile.

Look at the actual figures. Work out your raw score by using the formula Correct x 2.00 minus Wrong x 0.50, out of a total of 200. Compare this score with the official qualifying threshold and with your particular Post-Category Code vacancy ratio.

It should be noted that the SSC modifies raw scores according to multi-shift normalization, so the difficulty of the shift is important.
