SSC CGL Undated PYQs

Question 1

A wholesaler sells a jacket to a retailer at a proﬁt of 5% and the retailer sells it to a customer at a proﬁt of 10%. If the customer pays Rs. 4158, what had it cost (in Rs) to the wholesaler?

Accepted Answer

Let the wholesaler's cost be x. Successive profits mean x × 1.05 × 1.10 = 4158. Solving this gives x × 1.155 = 4158, so x = 3600.

Question 2

The flight fare between two cities is increased in the ratio 9:11. What is the increase (in Rs) in the fare, if the original fare was Rs. 18,000?

Accepted Answer

The original fare corresponds to 9 parts, so 1 part = 18000 / 9 = 2000. The increase is 11 - 9 = 2 parts. Thus, the increase is 2 × 2000 = Rs. 4000.

Question 3

A bag has Rs 43 in the form of 5-rupee, 50-paise and 10-paise coins in the ratio of 1:5:11. What is the total number of 50-paise coins?

Accepted Answer

Let the coins be x, 5x, and 11x. Total value in rupees: 5x + 0.5(5x) + 0.1(11x) = 43. So, 8.6x = 43, giving x = 5. Number of 50-paise coins = 5x = 25.

Question 4

Select the related number from the given alternatives. 64 : 8 :: 0.01 : ?

Accepted Answer

The relationship is based on the square root of the first number. Since √64 = 8, applying the same logic, the square root of 0.01 is 0.1.

Question 5

Sandy and Mandy do (8/13)th part of a work and the rest of the work was completed by Andy. If Sandy, Mandy and Andy take the same work for Rs 2600, then what is the share (in Rs) of Andy?

Accepted Answer

Andy's share of the work is 1 - 8/13 = 5/13. Since wages are distributed in proportion to the work done, Andy's share is (5/13) × 2600 = Rs 1000.

Question 6

Who takes the decision regarding the savings and loan activities in a Self Help Group (SHG)?

Accepted Answer

In a Self Help Group (SHG), all major decisions regarding savings, loan amounts, interest rates, and repayment schedules are taken democratically by the members of the group themselves.

Question 7

If "–" means "added to", "+" means "divided by", "÷" means "multiplied by", "x" means "subtracted from", then 13 + 12 x 9 ÷ 3 – 6 = ?

Accepted Answer

Replace symbols to get 13 ÷ 12 - 9 x 3 + 6. Applying BODMAS: 13/12 - 27 + 6 = 13/12 - 21 = (13 - 252)/12 = -239/12.

Question 8

The northern plain of India has been formed by the interplay of the three major river systems, namely– the Indus, the Ganga and the ___________.

Accepted Answer

The northern plains of India are formed by the extensive alluvial deposits brought down by three major Himalayan river systems: the Indus, the Ganga, and the Brahmaputra.

Question 9

If x2+ y2 + z2 = xy + yz + zx, then what is the value of (7x + 3y – 5z)/5x?

Accepted Answer

The given condition x2 + y2 + z2 = xy + yz + zx implies x = y = z. Substituting y and z with x in the expression gives (7x + 3x - 5x)/5x = 5x/5x = 1.

Question 10

In March 2017, in which country was "world's largest artificial sun" switched on?

Accepted Answer

In March 2017, Germany switched on 'Synlight', the world's largest artificial sun. It uses 149 giant xenon short-arc lamps to simulate sunlight for producing climate-friendly solar fuels like hydrogen.

Question 11

Which article was referred to as the 'the heart and soul' of the constitution by Dr. B. R. Ambedkar?

Accepted Answer

Article 32 provides the right to constitutional remedies, allowing citizens to approach the Supreme Court to protect fundamental rights. Hence, Dr. Ambedkar called it the heart and soul.

Question 12

Who invented the waterproof raincoat?

Accepted Answer

Scottish chemist Charles Macintosh invented the waterproof raincoat in 1823. He achieved this by sandwiching a layer of liquid rubber between two pieces of fabric, making it impermeable to water.

Question 13

If Pujara has scored 1875 runs in total, then what is the difference in runs scored by Pujara against South Africa and New Zealand? ?

Accepted Answer

Based on the given data chart, the difference in percentage between South Africa and New Zealand is 8%. Calculating 8% of the total 1875 runs gives (8/100) × 1875 = 150 runs.

Question 14

The ratio of present ages of L and N is 7 : 5. If the age of N after seven years will be 32 years, then what is the present age (in years) of L?

Accepted Answer

N's present age is 32 - 7 = 25 years. Since the ratio of L to N is 7:5, 5 units = 25, so 1 unit = 5. L's present age is 7 × 5 = 35 years.

Question 15

Energy in the form of heat is wasted when a machine is operated. This heat is generated due to ___________.

Accepted Answer

When machine parts move against each other, friction opposes the motion, converting kinetic energy into wasted heat energy.

Question 16

Accepted Answer

Fyodor Pirotsky, a Ukrainian-born engineer, invented the world's first electric tram in 1880. He successfully tested it in Saint Petersburg, revolutionizing urban public transportation.

Accepted Answer

Siraj ud-Daulah, the Nawab of Bengal, was defeated by the British East India Company led by Robert Clive in the Battle of Plassey on June 23, 1757.

Question 19

If tan2 θ + cot2 θ = 2, then what is the value of 2sec θ cosec θ?

Accepted Answer

Given tan²θ + cot²θ = 2, we get (tanθ - cotθ)² = 0, so tanθ = cotθ, meaning θ = 45°. Thus, 2sec(45°)cosec(45°) = 2(√2)(√2) = 4.

Question 20

In the following question, select the missing number from the given series. 3, 7, 16, 35, ?

Accepted Answer

The pattern is multiply by 2 and add consecutive integers: 3×2+1=7, 7×2+2=16, 16×2+3=35. So, the next number is 35×2+4 = 74.
