SSC CGL Undated PYQs

Question 1

The demand for a normal good increases with ________ in the consumer's income.

Accepted Answer

Normal goods have a positive income elasticity of demand. As a consumer's income increases, their purchasing power rises, leading to a higher demand for these goods.

Question 2

If θ is acute angle and tan θ – cot θ = 0, then what is the value of tan26 θ + cot100 θ?

Accepted Answer

Since tan θ - cot θ = 0, tan θ = cot θ, which means θ = 45°. Both tan 45° and cot 45° are 1. Thus, 1^26 + 1^100 = 1 + 1 = 2.

Question 3

Smaller diagonal of a rhombus is equal to length of its sides. If length of each side is 6 cm, then what is the area (in cm2) of an equilateral triangle whose side is equal to the bigger diagonal of the rhombus? ?

Accepted Answer

Side a=6, smaller diagonal d1=6. Using d1² + d2² = 4a², we get 36 + d2² = 144, so d2 = 6√3. Area of the equilateral triangle = (√3/4) × (6√3)² = 27√3.

Question 4

What is the HCF of 6345 and 2160?

Accepted Answer

Find the prime factorization: 2160 = 2⁴×3³×5 and 6345 = 3³×5×47. The highest common factor is the product of the lowest powers of common primes: 3³×5 = 135.

Question 5

Which of the following is not among the three different forms of 'if' statement?

Accepted Answer

In programming, the standard conditional statements are 'if', 'if...else', and 'if...else if...else'. 'if...and' is not a valid conditional structure; 'and' is a logical operator used inside conditions.

Question 6

Improve the bracketed part of the sentence. I had (not only helped her by) giving hints but also with providing him links.

Accepted Answer

The correlative conjunction 'not only... but also' requires parallel structures. The correct placement is 'helped her not only by giving hints but also by providing links'.

Question 7

Select the odd word from the given alternatives.

Accepted Answer

Carrot, radish, and beet are root vegetables that grow underground. Brinjal is the only vegetable here that grows above the ground, making it the odd one out.

Question 8

How much tax (in Rs '000 crores) was paid by XYZ limited in Y7?

Accepted Answer

Based on the provided data chart or table for year Y7, the tax paid by XYZ limited is calculated or directly read as 118.8 thousand crore rupees.

Question 9

Simple Interest received by a person in 10 years on a principal of Rs 9500 is 130% of the principal. What is the rate of interest (in %) per annum?

Accepted Answer

The total interest is 130% of the principal over 10 years. Since simple interest is constant every year, the annual rate is simply 130% / 10 = 13%. The principal amount (9500) is unnecessary.

Question 10

In the biosphere living beings are inter-related and interdependent on each other for survival. This life supporting system is known as the __________.

Accepted Answer

An ecosystem is a biological community of interacting organisms and their physical environment, forming a complete life-supporting system where all elements are interdependent.

Question 11

Which among the following is the major cause of acid rain? ?

Accepted Answer

Acid rain is primarily caused by emissions of sulfur dioxide (SO2) and nitrogen dioxide (NO2), which react with water in the atmosphere to form sulfuric and nitric acids.

Question 12

What is the SI unit of temperature?

Accepted Answer

The International System of Units (SI) defines Kelvin as the base unit of temperature. Unlike Celsius or Fahrenheit, it starts at absolute zero, making it essential for scientific calculations.

Question 13

What is the simplified value of (cos A + sin A)(cot A + tan A)? ?

Accepted Answer

Convert cot A and tan A to sin/cos. (cot A + tan A) becomes 1/(sin A cos A). Multiplying by (cos A + sin A) gives 1/sin A + 1/cos A, which is cosec A + sec A.

Question 14

Δ LMN is right angled at M. If m∠N = 60o., then Tan L =______.

Accepted Answer

In right ΔLMN, ∠M = 90° and ∠N = 60°. Thus, ∠L = 180° - (90° + 60°) = 30°. The value of Tan L is Tan 30° = 1/√3.

Question 15

Which neighbouring country of India is also reffered as 'Druk Yul'?

Accepted Answer

Bhutan is known as 'Druk Yul', which translates to 'Land of the Thunder Dragon' in the native Dzongkha language, reflecting its rich cultural and mythological heritage.

Question 16

Which of the following was the winner of the Grammy Awards 2016 "Country Song of the Year"?

Accepted Answer

"Girl Crush" by Little Big Town won the Grammy Award for Best Country Song in 2016. It was a massive hit written by Lori McKenna, Hillary Lindsey, and Liz Rose.

Question 17

Captain Manoj Kumar Pandey was awarded the Paramvir Chakra for his martyrdom at which of the following wars?

Accepted Answer

Captain Manoj Kumar Pandey was posthumously awarded India's highest military honor, the Param Vir Chakra, for his exceptional courage and leadership during the 1999 Kargil War against Pakistan.

Question 18

The present population of a town is 26010. It increases annually at the rate of 2%. What was the population of town 2 years ago?

Accepted Answer

Let the population 2 years ago be P. Using the compounding formula: P × (102/100)² = 26010. This simplifies to P × (2601/2500) = 26010, which gives P = 25000.

Question 19

One of the diagonal of a rhombus is 70% of the other diagonal. What is the ratio of area of rhombus to the square of the length of the larger diagonal?

Accepted Answer

Let the larger diagonal be 10x, so the smaller is 7x. Area = (1/2) × 10x × 7x = 35x². Square of larger diagonal = 100x². Ratio = 35x² : 100x² = 7 : 20.

Question 20

Two labourers A and B are paid a total of Rs. 750 per day. If A is paid 150 percent of what is paid to B, how much (in Rs) is B paid?

Accepted Answer

A gets 1.5 times B. So, A + B = 2.5B = 750. Solving for B gives 750 / 2.5 = 300. Thus, B is paid Rs. 300.
