Hexaware Reasoning Ability Questions
Q1) The question given below is followed by two statements numbered I and II. Determine if the statements are, individually or together sufficient to answer the question.
Question: What is the first term in a sequence of numbers?
Statements:
I. The third term is 12.
II. The second term is twice the first and the third term is three times the second.
A. Statements I and II together are not sufficient to answer the question asked and additional data to the problem is needed.
B. Only one of the statements, alone, is sufficient to answer the question but other statement is not.
C. Each statement alone is sufficient to answer the question.
D. Both statements I and II together are sufficient to answer the question asked but neither statement alone is sufficient.
Explanation: Let, three terms be x, y and z.
S1 alone – 3rd term, z = 12.
No information regarding the first two terms. So, statement 1 alone can’t answer.
S2 alone: y = 2x and z = 3y.
From S2, we get x : y :z = 1 : 2 : 3.
x = 1p
y = 2p
z = 3p.
But value of first term is still unknown. Using S2 alone can’t answer the question.
Using S1 and S2 together, z = 12, z = 3p. So, 3p = 12. p = 4.
So, first term = p = 4.
So, both 1 and 2 together can answer the question. Hence, answer is option D.
A. 3118
B. 3281
C. 3181
D. 3218
Explanation: Given, F = 6, E J Z = 5 10 26, M A T = 13 1 20.
These are the place values of alphabets given in the words.
So, CAR = 3118. So, answer is option A.
4400, 4437, 4472, ?, 4536, 4565
A. 4522
B. 4026
C. 4526
D. 4505
Explanation: 4400 + 37 = 4437
4437 + 35 = 4472
4472 + 33 = 4505
4505 + 31 = 4536
4536 + 29 = 4565.
So, the logic is, +37, +35, +33, +31 and +29.
So, the required missing number is 4472 + 32 = 4505. Correct answer is option D.
Question: What is the value of x?
Statements:
I. x - 2y = 7
II. 4x - 28 = 8y
A.Both statements I and II together are sufficient to answer the question asked but neither statement alone is sufficient
B.Each statement alone is sufficient to answer the question
C.Statements I and II together are not sufficient to answer the question asked and additional data to the problem is needed.
D.Only one of the statements, alone, is sufficient to answer the question but the other statement is not
Explanation: Statement I alone or Statement II alone can’t answer the question.
By, observing mostly people think, solving I and II together can answer but no, solving I and II together even, you can’t even get the value of x.
Since equation 1 and 2 are having infinite solutions.
So, Option C is the answer.
In a parking lot, 5 cars each are parked in two parallel lines facing each other. Benz, XUV, Duster, Eco sports, and Scorpio are parked facing South while Zen, i20, i10, Polo, and Brio are parked facing North.
- XUV is parked to the immediate left of Eco sports and is opposite to Brio.
- Duster and i20 are parked diagonally opposite.
- Scorpio is parked opposite to i10 which is to the immediate right of Zen.
- Polo is parked to the immediate left of Brio and is opposite to Eco sports.
- Zen is parked to one of the extremes.
Which car is parked third to the right of i10?
A. Zen
B. i20
C. Cannot be determined
D. Brio
Explanation: The arrangement as per the given conditions is as follows,
Duster Scorpio Eco Sports XUV Benz
Zen i10 Polo Brio i20.
3rd to the right of i10 is i20. So, correct option is B.
2, 3, 5, 7, 11, (....), 17
A. 12
B. 13
C. 14
D. 15
Explanation: The given series is a prime number series. So, the missing prime number is 13. So, option B is the correct answer.
A.Copper
B.Iron
C.Iodine
D.Tin
Explanation: The odd one is Iodine. Because the others are metal and are in normally solid state but in case of Iodine it is not metal and it normally appears as liquid.
The principal instructed all the teachers to be careful in class because some students may disturb other students.
Assumptions:
I. The teachers may handle the situation properly and they may restrict the naughty students.
II. The students will welcome the decision of the Principal.
A. If only assumption I is implicit
B. If only assumption II is implicit
C. If either I or II is implicit
D. If neither I nor II is implicit
Explanation: Clearly, teachers have been instructed to maintain discipline in the class and point out the naughty students who do not let other students’ study. So, statement I is implicit. Regarding students welcoming or not we can’t decide that, so II doesn’t implicit.
A man walks 5 km towards south and then turns right. After walking 3 km he turns to the left and walks 5 km. Now in which direction is he from the starting place?
A.West
B.South
C.North East
D.South West
Explanation: The direction from the starting point is South-west
Event (B): Company X has chalked out an expansion plan, involving raising
production capacity at its existing plants.
A. If 'A' is the effect and 'B' is its immediate and principle cause.
B. If 'B' is the effect and 'A' is its immediate and principle cause.
C. If 'A' is the effect but 'B' is not its immediate and principle cause.
D. If 'B' is the effect but 'A' is not its immediate and principle cause.
Explanation: Events (A) and (B) are related events and chronologically (B) occurs before (A) and because of as they are planning to increase capacity, they have to make a plan to sell their products also so they open new offices for marketing those products. But opening an office in a particular city, requires other events such as market survey etc. It is not the immediate and principle cause.
A.15495
B. 16208
C. 14782
D. 16921
Explanation: 522+(713*1) =1235
1235+(713*2) =2661
2661+(713*3) =4800
4800+(713*4) =7652
7652+(713*5) =11217
11217+(713*6) =15495

A word and number arrangement machine when given an input line of words and numbers rearranges them following a particular rule in each step.
The following isan illustration of input and rearrangement:
Input: 39 121 48 18 76 112 14 45 63 96
Step I: 14 39 121 48 18 76 112 45 63 96
Step II: 14 39 48 18 76 112 45 63 96 121
Step III: 14 18 39 48 76 112 45 63 96 121
Step IV: 14 18 39 48 76 45 63 96 112 121
Step V: 14 18 39 45 48 76 63 96 112 121
Step VI: 14 18 39 45 48 63 76 96 112 121
This is the final arrangement and step VI is the last step for this input.
How many steps will be required for getting the final output for the following input?
Input: 101 85 66 49 73 39 142 25 115 74
A. 5
B. 6
C. 7
D. 8
Explanation: Step I: The smallest number becomes first and the remaining numbers shift one position rightward.
Step II: The largest number among given numbers becomes last and the remaining numbers shift one position leftward.
The steps are repeated alternately till all the numbers get arranged in ascending order and that will be that last step for that particular input. Hence 8 steps
