GATE 2022 Aptitude Questions
As the questions are memory-based, for most of the questions, it is not sure to say whether the question is MCQ or NAT. But, the question is correct to the best of our knowledge.
We will be updating this blog with more memory-based questions. Keep coming back for more. The official key will be out soon on the GATE official website.
Question 1
A cube is having a spherical ball of radius r placed inside such that it just fits in. The volume of the cube in terms of r required will be ____
a) 8r^3 b) 4r^3
c) r^3 d) 4r^2
Hint
This is a very simple question. To fit in a spherical ball perfectly into a cube with side 'a', the diameter of the sphere must be equal to the side of the cube.
i.e., 2r = a
The volume of cube = a^3 = (2r)^3. Therefore, the answer is 8r^3.
Question 2
The seating arrangement for six persons is based on the following conditions.
P sits next to S and T
Q sits diametrically opposite to P
Shortest between S and R equal to the shortest distance between T and U
Then Q is the neighbour of _____
a) S and T b) S and P
c) U ant T d) R and U
Hint
This question requires knowledge of seating arrangements. In this particular question, the conditions for arrangement is fairly easy. The only tricky word to understand is "diametrically opposite" which simply means sitting opposite to each other in a circular seating arrangement. Therefore, getting the right seating arrangement will help in finding the answer.
The answer to this question for your reference is R and U.
Question 3
From the statements and conclusions given below, identify the conclusions that could be logically inferred
Statement 1: Some engineers are writers
Statement 2: No writer is an actor
Statement 3: All actors are engineers
Conclusion 1: Some writers are engineers
Conclusion 2: All engineers are actors
Conclusion 3: No actor is a writer
Conclusion 4: Some actors are writers
a) Conclusion 1 only follows b) Conclusion 1 and 3 follows
c) Conclusion 1 and 4 follows d) Conclusion 3 only follows
Hint
To solve this question, knowledge of syllogism is required. Syllogism involves forming Venn diagrams out of given statements and inferring them to find out the logical conclusions.
Given below are the Venn diagrams for the three statements mentioned in the question, inferring which helps in finding out the logical conclusions.
Therefore, conclusions 1 and 3 follows.
Question 4
A sum of money is to be distributed among P, Q, R and S in the proportion 5:2:4:3 respectively. If R gets 1000 more than S, what is the share of Q
a) 3000 b) 4000
c) 2000 d) 2200
Hint
Framing the equation will be enough to instantly get the correct answer for this question.
Let's assume that amounts P, Q, R, and S will get are 5x, 2x, 4x, and 3x respectively. From the question,
4x = 3x + 1000
x = 1000
Here is the tricky part, our objective is not to find x value, our objective is to find the share of Q which is 2x. Therefore, the answer is 2000.
Question 5
Consider the following inequalities
2x - 1 > 7
2x - 9 < 1
Which of the following expressions satisfy the above two inequalities?
a) x ≤ -4 b) -4 < x ≤ 4
c) x ≥ 5 d) 4 < x < 5
Hint
This is a simple question. Solve both the inequalities to get the necessary condition to satisfy the same inequality.
2x-1>7 ⇒ 2x>8 ⇒ x>4
2x-9<1 ⇒ 2x<10 ⇒ x<5
The answer for this question by above said method is d) 4 < x < 5
Question 6
Four points P(0,1), Q(0,-3), R(-2,-1) and S(2,-1) represents the vertices of a quadrilateral. What is the area enclosed by the quadrilateral?
a) 8√2 b) 2√2
c) 8 d)4
Hint
Plot the graph and try to find the dimensions of the quadrilateral. As the sides are known imagine the quadrilateral as two triangles and summing the area of those two triangles gives the area of the quadrilateral.
For ease, the graph is given below. And the answer is 8 unit^2.
Question 7
Consider the following inequalities
3p - q > 4
3q - p < 12
Which of the following expressions satisfy the above two inequalities?
a) p+q<8 b) 8 ≤ p+q<16
c) p+q ≥ 16 d) p+q = 8
Hint
This is a simple question. Solve both the inequalities to get the necessary condition to satisfy the same inequality. Adding the two inequalities,
2p + 2q <16 ⇒ p+q < 8
Therefore, the answer is a) p+q<8.
Question 8
Two pipes A and B can fill a storage tank with water in 10 and 6 minutes respectively. Pipe C draws out from the storage tank at a rate of 34 litres per minute. A, B, and C operate at a constant rate. If it takes one hour to completely empty a full storage take with all the pipes operating simultaneously. What is the capacity of the storage tank (in litres)?
a) 120 b) 60
c) 26.8 d) 127.5
Hint
Solving this question requires knowledge of work and time relations. Here the tank is already full and still pipe C successfully withdraws the entire tank. Therefore, work done by C in1 a minute can be found as,
60/17 (i.e, total time/(A+B+1))
It is said in the question that C operates at 34 litres per minute. Now, by multiplying the 1 min work done by C to empty the tank with the discharge of pipe C the tank capacity could be found as,
460/17* 34 = 120 litres.
Therefore, the answer is 120 litres.
Question 9
Mr. X speaks _____ japanesse _____chinesse
a) neither - nor b) also - but
c) either - nor d) neither - but
Hint
Knowledge of conjunction is enough to answer this question. The correct answer is a) neither - nor.
Question 10
Given the sides of a trapezium, find the shortest distance between PQ and RS which are opposite to each other. PQ = 11, QR = 4, RS = 6, RP = 3.
Hint
The shortest distance between PQ and RS is shown below.
a+b = 5
By Pythagoreans theorem,
x^2 + a^2 = 3^2,
x^2 + b^2 = 4^2
Subtract the above equations, we get,
b^2 - a^2 = 16 - 9 ⇒ 7
(b-a) * (b+a) = 7 ⇒ b-a = 7/5, and b+a = 5, on solving these two equations, we get,
a = 9/5, and b = 16/5
Now,
x^2 = 16 - 9/5 ⇒ x = 2.4
