SSC CGL Undated PYQs

Question 1

What is the effective discount (in %) on two successive discounts of 15% and 50%?

Accepted Answer

Use the successive discount formula: x + y - (xy/100). Here, 15 + 50 - (15 × 50)/100 = 65 - 7.5 = 57.5%.

Question 2

Who amongst the following is a renowned vocalist?

Accepted Answer

Pandit Jasraj was a legendary Indian classical vocalist belonging to the Mewati gharana. The other options are associated with dance (Reddy) and painting (Bawa, Verma).

Question 3

The cost price of an article is x. It is marked up by 150%. It is sold at Rs 600 after giving 40% discount. What is x (in Rs)?

Accepted Answer

Marked price is 2.5x (x + 150% of x). After a 40% discount, selling price becomes 60% of 2.5x, which is 1.5x. Equating 1.5x to 600 gives x = 400.

Question 4

What is the cumulative profits (in lakh Rs) earned by the company in the given six years?

Accepted Answer

To find the cumulative profit, simply add the individual profits of all six given years from the provided data chart. The total sum equals 70 lakh Rs.

Question 5

If "P" denotes "multiplied by", "R" denotes "subtracted from", "S" denotes "added to" and "Q" denotes "divided by", then which of the following equation is true?

Accepted Answer

Substitute the symbols in option 2: 15 + 16 ÷ 2 × 4. Using BODMAS, first divide (16÷2=8), then multiply (8×4=32), and finally add (15+32=47).

Question 6

ΔXYZ is similar to ΔPQR. If ratio of Perimeter of ΔXYZ and Perimeter of ΔPQR is 4:9 and if PQ = 27 cm, then what is the length of XY (in cm)?

Accepted Answer

For similar triangles, the ratio of perimeters equals the ratio of corresponding sides. So, Perimeter(XYZ)/Perimeter(PQR) = XY/PQ. 4/9 = XY/27. XY = (4 × 27) / 9 = 12 cm.

Question 7

In a class of 50 students there are 27 boys. The average weight of these boys is 72 Kg and average weight of the full class is 55.44 kgs. What is the average weight (in kgs) of the girls of the class?

Accepted Answer

Total weight of class = 50 × 55.44 = 2772 kg. Total weight of boys = 27 × 72 = 1944 kg. Girls' weight = 2772 - 1944 = 828 kg. Average = 828 / 23 = 36 kg.

Question 8

If total time taken to make a car is 300 hours, then what is the total time (in hours) taken in paint and frame?

Accepted Answer

Based on the correct answer, the combined share for paint and frame in the given chart is 35%. Calculating 35% of 300 hours gives 105 hours.

Question 9

Speed of light is maximum in _____.

Accepted Answer

The speed of light is maximum in a vacuum (approx 3×10^8 m/s) because there are no particles to obstruct or scatter the light waves, unlike in other mediums.

Question 10

What is the value of 1/√2 Cot 30° + 1/√3 Cosec 60°?

Accepted Answer

Cot 30° = √3 and Cosec 60° = 2/√3. Substitute these values: (1/√2)(√3) + (1/√3)(2/√3) = √(3/2) + 2/3 = (3√3 + 2√2) / 3√2.

Question 11

______________ scheme launched by the Central Government aims to improve rural livelihoods and promote rural development and strengthen the Panchayati Raj across the country.

Accepted Answer

'Gram Uday Se Bharat Uday Abhiyan' was launched in 2016 to strengthen Panchayati Raj institutions, promote rural development, and foster social harmony across villages in India.

Question 12

If Tan θ = 7/24, then what is the value of Cosec θ?

Accepted Answer

Tan θ = Perpendicular/Base = 7/24. By Pythagoras theorem, Hypotenuse = √(7² + 24²) = 25. Cosec θ = Hypotenuse/Perpendicular = 25/7.

Question 13

A series is given with one term missing. Select the correct alternative from the given ones that will complete the series. A, E, I, M, ? A, E, I, M, ? 9/7/2017 Staff Selection Commision http://thepracticetest.in/cs_cglet1_17/response_questions.php?t_id=MTIwODIwMTc=&appid=1368062d74107fc05177712c90c3885c 3/28

Accepted Answer

Each letter moves forward by 4 positions in the alphabetical order: A(+4) = E, E(+4) = I, I(+4) = M, and M(+4) = Q.

Question 14

Pointing to a lady, Diwakar said, "Her mother's only grandson is my son." How is that lady related to Diwakar?

Accepted Answer

The lady's mother's grandson is Diwakar's son. This implies the lady's mother is also Diwakar's mother. Therefore, Diwakar and the lady are siblings, making her his sister.

Accepted Answer

England hosted the 2015 Men's Rugby World Cup. New Zealand won the tournament by defeating Australia in the final, becoming the first team to win back-to-back titles.

Question 16

What is the value of Sin 60° + (1/2)Cosec 45°?

Accepted Answer

Sin 60° = √3/2 and Cosec 45° = √2. Substituting these values gives √3/2 + (1/2)√2 = (√3 + √2)/2.

Question 17

The company's expenditure on interest is greater than expenditure on rent by

Accepted Answer

Based on the data chart, if interest is double the rent, the difference equals the rent itself. Thus, the percentage increase is (Difference/Rent) × 100 = 100%.

Question 18

A woman in a shopping complex walks 250 m East, then she turns North and walks 100 m, then she turns West and walks 120 m, then she turns to her left and walks 100 m. Where is she now with reference to her starting position?

Accepted Answer

She moves 250m East, 100m North, 120m West, and 100m South (left turn). The North and South distances cancel out. Net distance is 250 - 120 = 130m East.

Question 19

In a certain code language, "MATCH" is written as "NYWYM" and "BOARD" is written as "CMDNI". How is "PRINT" written in that code language?

Accepted Answer

The pattern is +1, -2, +3, -4, +5 for consecutive letters. Applying this to PRINT: P+1=Q, R-2=P, I+3=L, N-4=J, T+5=Y, giving QPLJY.
