SSC CGL Undated PYQs

Question 1

If 5x - (1/2)(2x -7) = 5.5, then what is the value of x?

Accepted Answer

Expand the bracket to get 5x - x + 3.5 = 5.5. Simplifying this gives 4x = 2, which results in x = 1/2.

Question 2

A student has to secure 40% marks to pass. He gets 67 and fails by 13 marks. What is the maximum marks?

Accepted Answer

Passing marks = 67 + 13 = 80. Since 40% of the maximum marks equals 80, the maximum marks = (80 / 40) * 100 = 200.

Question 3

A, B and C can do a job working alone in 12, 16 and 24 days respectively. In how many days they can do the job if they worked together?

Accepted Answer

Total work = LCM(12, 16, 24) = 48 units. Efficiencies: A=4, B=3, C=2. Total efficiency = 4+3+2 = 9. Time taken together = 48/9 = 16/3 days.

Question 4

If an object moves in a circular path with uniform ________, its motion is called uniform circular motion.

Accepted Answer

In uniform circular motion, the object's speed remains constant while its velocity constantly changes due to the continuous change in direction along the circular path.

Question 10

In the following question, by using which mathematical operators will the expression become correct? 15 _ 3 _ 4 _ 20 15 _ 3 _ 4 _ 20

Accepted Answer

Substitute the operators from option 3: 15 ÷ 3 × 4 = 20. According to BODMAS, first divide (15 ÷ 3 = 5), then multiply (5 × 4 = 20). The equation is perfectly balanced.

Question 11

Accepted Answer

Complex animals are made of exactly four basic tissue types: epithelial, connective, muscle, and nervous tissue. These combine to form all organs and systems.

Question 12

In ____________, the short run equilibrium results in quantity produced being lesser and prices being higher compared to perfect competition.

Accepted Answer

In monopolistic competition, product differentiation gives firms some market power. This downward-sloping demand curve leads to higher prices and lower output compared to perfect competition in the short run.

___________ is an alternative way of representing the production function.

Accepted Answer

An isoquant curve shows all the different combinations of inputs (like labor and capital) that produce the same level of output, serving as an alternative graphical representation of a production function.

Question 17

A ball rolling along the ground gradually slows down and finally comes to rest is due to ________. 9/7/2017 Staff Selection Commision

Accepted Answer

Friction is an opposing force that acts between the rolling ball and the ground. It resists the ball's motion, gradually reducing its kinetic energy until it stops.

Question 18

Sum of a fraction and thrice of its reciprocal is 73/20. What is the fraction?

Accepted Answer

Let the fraction be x. The equation is x + 3/x = 73/20. By checking the options, for x = 5/4, we get 5/4 + 12/5 = (25+48)/20 = 73/20.

Question 19

Point P (-2, 5) is the midpoint of segment AB. Co-ordinates of A are (-5, y) and B are (x, 3). What is the value of x?

Accepted Answer

The x-coordinate of the midpoint is the average of the x-coordinates of the endpoints. So, -2 = (-5 + x) / 2. Multiplying by 2 gives -4 = -5 + x, hence x = 1.

Question 20

How many times a person can be elected as the President of India? ?
