Latest Number Arrangement MCQ Objective Questions
Number Arrangement Question 1:
If 2 is added to each even digit and 2 is added to each odd digit in the number 5217643, what will be the sum of the first digit from the left and the first digit from the right in the new number thus formed?
Answer (Detailed Solution Below)
Number Arrangement Question 1 Detailed Solution
Given:
5217643
2 is added to each even digit and 2 is added to each odd digit in the number
Original Digit | 5 (Odd) | 2 (Even) | 1 (Odd) | 7 (Odd) | 6 (Even) | 4 (Even) | 3 (Odd) |
---|---|---|---|---|---|---|---|
Operation (+2) | 5 + 2 = 7 | 2 + 2 = 4 | 1 + 2 = 3 | 7 + 2 = 9 | 6 + 2 = 8 | 4 + 2 = 6 | 3 + 2 = 5 |
New Digit | 7 | 4 | 3 | 9 | 8 | 6 | 5 |
New Number: 7 4 3 9 8 6 5
The sum of the first digit from the left and the first digit from the right in the new number thus formed
7 + 5 = 12.
Hence, the correct answer is "Option 4".
Number Arrangement Question 2:
This question is based on the five, three-digit numbers given below.
(Left) 401 418 733 283 902 (Right)
(Example: 697 – First digit = 6, second digit = 9 and third digit = 7)
(NOTE: All operations to be done from left to right.)
What will be the resultant if the second digit of the highest number is added to the third digit of the lowest number?
Answer (Detailed Solution Below)
Number Arrangement Question 2 Detailed Solution
Given: (Left) 401 418 733 283 902 (Right)
The highest number is: 902
The second digit of the highest number is: 0
And,
The lowest number is: 283
The third digit of the lowest number is: 3
So, the addition of the second digit of the highest number and the third digit of the lowest number is:
→ 0 + 3 = 3.
The correct answer is "Option 4".
Number Arrangement Question 3:
This question is based on the five, three-digit numbers given below.
(Left) 614 457 249 625 150 (Right)
(Example: 697 – First digit = 6, second digit = 9 and third digit = 7)
(NOTE: All operations to be done from left to right.)
What will be the resultant if the second digit of the highest number is subtracted from the second digit of the lowest number?
Answer (Detailed Solution Below)
Number Arrangement Question 3 Detailed Solution
The given numbers are: 614, 457, 249, 625, 150.
The highest number in the list is 625.
The second digit of 625 is 2.
The lowest number in the list is 150.
The second digit of 150 is 5.
Subtract the second digit of the highest number (2) from the second digit of the lowest number (5).
Resultant = 5 - 2 = 3.
Thus, the resultant is 3.
Hence, the correct answer is "Option 4".
Number Arrangement Question 4:
If 4 is subtracted from all the digits greater than 6 and 3 is added to all the digits less than 6 in the number '14579283', then how many digits are repeated in the newly formed number?
Answer (Detailed Solution Below)
Number Arrangement Question 4 Detailed Solution
Given: The number is '14579283'
Mathematical Operation: 4 is subtracted from all the digits greater than 6 and 3 is added to all the digits less than 6.
After following the operation given in the question, we get the newly the formed number as follows:

There is a gap of two digits in every number like, there are 5 and 5 between 8 and 3 in 83.
Similarly, there are 7 and 2 between 3 and 5 in 35 and 7 and 8 between 8 and 1 in 81. But there are 5, 8, 8, and 7 between 2 and 7 in 27.
Hence, 27 does not belong to the group.

Directions: Answer the questions based on the information given below:
378 256 431 875 762
If first and third digits of the given numbers are subtracted then which of the following number will give the second highest resultant?
Answer (Detailed Solution Below)
Number Arrangement Question 9 Detailed Solution
Download Solution PDFGiven numbers: 378 256 431 875 762
On subtracting first and third digits,
378 = 8 – 3 = 5
256 = 6 – 2 = 4
431 = 4 – 1 = 3
875 = 8 – 5 = 3
762 = 7 – 2 = 5
Hence, 4 is the second highest resultant which is obtained from 256.
