Night Class: Reasoning Quiz

Directions (Q. 1–2): In each question below is given a statement followed by two assumption numbered I and II. (An assumption is something supposed or taken for granted). You have to consider the statement and the following assumption and decide which of the assumption is implicit in the statement. Give answer

1. If only assumption I is implicit.
2. If only assumption II is implicit.
3. If either assumption I or assumption II is implicit.
4. If neither assumption I nor assumption II is implicit.
5. If both assumption I and II are implicit.

1. Statement : A very large number of people stood in the queue for buying tickets for the rock concert to be made in the city next day.

Directions (Q. 3–5): Following question are based on the five 3-digit number given below:

519 328 746 495 837

3. If half of the second largest number is subtracted from the third largest number, what will be the value?
1) 156 
2) 146 
3) 213 
4) 314 
5) 246

4. If the position of first and the third digits in each of the numbers are interchanged, which of the following will be the second digit of the lowest number?
1) 1 
2) 2 
3) 4 
4) 9 
5) 3

5. If the position of all the digits in each of the numbers are interchanged i.e. first becomes second, second become third and third becomes first, which of the number becomes the highest number?
1) 378 
2) 495 
3) 837 
4) 746 
5) 519

Directions (Q. 6–10): Each of the questions below consists of a question and two statements numbered I and II given it. You have to decide whether the data provided in the statements are sufficient to answer the question. Read both the statement and give answer.

1) if the data in statement I alone are sufficient to answer the question, while the data in statement II alone are not sufficient to answer the question.
2) if the data in statement II alone are sufficient to answer the question, while the data in statement I alone are not sufficient to answer the question.
3) if the data either in statement I alone or in statement II alone are sufficient to answer the question.
4) if the data in both the statement I and II together are not sufficient to answer the question.
5) if the data in both the statement I and II together are necessary to answer the question.

6. What is the value of a^13?
I. a is a prime number.
II. a is an even number.

7. What is the value of z?
I. 3x/(9 – 6z) = 2 
II. x = 6 – 4z

8. In which direction is Rahul facing?
I. If Karan who is currently facing East, turns 90° towards his right, he would face a direction exactly opposite to the direction which Rahul is facing.
II. If Priya, who is currently facing South, turns left and walks 1m and turns left again, she would face the same direction of Rahul.

9. How is Y related to N?
I. Y is mother of F. J is married to T. Z is daughter of J. T is brother of F.
II. Y is married to U. U is father of F. F is married to L. F is uncle of N.

10. If B > X and A >= D are definitely true, what will come in the place of blank spaces in the given expression?

W = X __ Y <= A __ B __ C >= D

1) < , = , >= 
2) > , = , >= 
3) <= , = , >=
4) >= , = , >= 
5) Other than given options



Answers:

1. 2

2.1

3. 2;
Second highest number = 746;
746/2 = 373
Third highest number = 519.
Difference = 519 – 373 = 146

4. 4;
519 = 915;
328 = 823;
746 = 647;
495 = 594;
837 = 738;
Lowest number = 594

5. 5;
519 = 951;
328 = 832;
746 = 674;
495 = 549;
837 = 783
Highest number = 951 or 519


6. 5;From I, ‘a’ is a prime number. But a unique value of a is not known, a can be 2, 3, 5, 7......... Hence, statement I
alone is not sufficient. From II, again a unique value of a
is not known, a can be 2, 4,6...Hence statement II alone is not sufficient. Combining I and II, that ‘a’ is even and
prime. Hence, I and II together are sufficient to answer
the question.

7. 4; From I and II, we get 2 equation in two variables. But
they are dependent. Thus, eventually we get one equation in two variables, which have infinite solution set.

8. 3; From statement I,
If Karan turns 90° towards his right, he will face South.
So, Rahul is facing North.
From statement II,
In the end, Priya faces North. So, Rahul also faces North.

9. 2
From I:

From II:

Hence, Y is grandmother of N.

10. 1; Check option by pick method.

By options
1) W = X < Y <= A = B >= C >= D
