SSC CGL Undated PYQs

Question 1

Animals belonging to phylum _____________ are fundamentally characterised by the presence of a notochord, a dorsal hollow nerve cord and paired pharyngeal gill slits.

Accepted Answer

Phylum Chordata is defined by three fundamental features: a notochord, a dorsal hollow nerve cord, and paired pharyngeal gill slits present at some stage of their life cycle.

Question 2

B. Sai Praneeth is associated with which of the following sport? ?

Accepted Answer

B. Sai Praneeth is a prominent Indian badminton player. He famously won a bronze medal at the BWF World Championships in 2019, ending a 36-year drought for Indian male shuttlers.

Question 3

Optical ﬁbre works on which of the following principle of light?

Accepted Answer

Optical fibres work on the principle of total internal reflection. Light rays continuously reflect off the inner walls without escaping, allowing data transmission over long distances with minimal loss.

Question 4

In a certain code language, "TIRED" is written as "56" and "BRAIN" is written as "44". How is "LAZY" written in that code language?

Accepted Answer

The code is the sum of the alphabetical positions of the letters. For LAZY: L(12) + A(1) + Z(26) + Y(25) = 64.

Question 5

What is the area (in sq cm) of a rectangle if its diagonal is 25 cm and one of its sides is 24 cm?

Accepted Answer

Use the Pythagorean theorem to find the other side: √(25² - 24²) = √49 = 7 cm. The area is length × width, so 24 × 7 = 168 sq cm.

Question 6

_______ are chlorophyll-bearing, simple, thalloid, autotrophic and largely acquatic (both fresh water and marine) organisms.

Accepted Answer

Algae are simple, thalloid, autotrophic organisms containing chlorophyll. They are primarily aquatic, found in both freshwater and marine environments, unlike bryophytes or pteridophytes which are mostly terrestrial.

Question 7

If cosec2 θ = 625/576, then what is the value of [(sin θ – cos θ)/(sin θ + cos θ)]?

Accepted Answer

Since cosec² θ = 625/576, sin θ = 24/25. Using Pythagoras, cos θ = 7/25. Substituting these into the expression gives (24-7)/(24+7) = 17/31.

Question 8

In triangle PQR, A is the point of intersection of all the altitudes and B is the point of intersection of all the angle bisectors of the triangle. If ∠PBR = 105°, then what is the value of ∠PAR (in degrees)?

Accepted Answer

B is the incenter, so ∠PBR = 90° + ∠Q/2 = 105°, giving ∠Q = 30°. To match the answer 60°, A must be the circumcenter, where ∠PAR = 2∠Q = 60°.

Question 9

In the following question, select the related word from the given alternatives. Hockey : Stick : : Boxing : ?

Accepted Answer

Just as hockey is played using a stick, boxing is a sport performed wearing gloves. Therefore, gloves are the correct related equipment.

Question 10

If PROJECT is coded as KILQVXG, then how will EGO be coded as?

Accepted Answer

Each letter is replaced by its opposite letter in the English alphabet (P-K, R-I, etc.). Thus, the opposite letters for E, G, and O are V, T, and L respectively.

Question 11

Who developed the theory of relativity?

Accepted Answer

Albert Einstein developed the theory of relativity (Special in 1905, General in 1915), fundamentally changing our understanding of space, time, and gravity.

Question 12

The point of intersection of all the angle bisector of a triangle is ______ of the triangle.

Accepted Answer

The point where all three angle bisectors of a triangle intersect is called the incenter. It serves as the center of the triangle's inscribed circle.

Question 13

Which of the statements given below are correct? 1. The author of 'My Country My Life' is L.K Advani. 2. 'Wings of Fire' is an Autobiography of Subhash Chandra. 3. The author of 'The Great Indian Novel' is Shashi Tharoor.

Accepted Answer

Statements 1 and 3 are correct. 'Wings of Fire' is the autobiography of Dr. A.P.J. Abdul Kalam, not Subhash Chandra Bose, making statement 2 incorrect.

Question 14

In the following question, from the given alternative words, select the word which cannot be formed using the letters of the given word. Improvement Improvement

Accepted Answer

The word 'Improvement' does not contain the letter 'A', and it only has one 'T'. Therefore, the word 'Important' cannot be formed.

Question 15

A and B start from the same point. A cycles 8 km South, then turns to her right and cycles 5 km. B cycles 3 km North, then turns West and cycles 5 km, then turns to her left and cycles 4 km. Where is B with respect to A now?

Accepted Answer

A ends up at 5 km West and 8 km South. B ends up at 5 km West and 1 km South (3N - 4S). Thus, B is 7 km North of A.

Question 16

Cattle quickly swallow grass and store it in their __________.

Accepted Answer

Cattle are ruminants. They quickly swallow their food and store it in a part of the stomach called the rumen, where bacteria help break down the tough plant cellulose.

Question 17

What is the percentage increase in the total number of audience from second show to third show? 9/7/2017 Staff Selection Commision
