Directions: Study the following information carefully and answer the questions given beside:

578     796     429     685     849
Important for :
1
If all the digits are arranged in increasing order from left to right within the number then what would be the difference between second highest and second lowest number thus obtained?
» Explain it
B
The given sequence:

578     796     429     685     849

Arranging all the digits in increasing order from left to right within the number, we get:

578     679     249     568     489

Second highest number = 578

Second lowest number = 489

Required Difference = 578 – 489 = 89

Hence, the correct answer is option B.
2
If first and last digit of each number is interchanged then what will the difference between the sum of even numbers and the sum of odd numbers thus obtained?
» Explain it
E
The given sequence:

578     796     429     685     849

Interchanging first and last digit of each number, we get

875     697     924     586     948

Sum of even numbers = 924 + 586 + 948 = 2458

Sum of odd numbers = 875 + 697 = 1572

Required Difference = 2458 – 1572 = 886

Hence, the correct answer is option E.
3
If 142 is subtracted from each of the given numbers and the digits of each of these numbers are sumed up then which of the following numbers will have the highest sum thus obtained?
» Explain it
C
The given sequence:

578     796     429     685     849

Subtracting 142 from each number of the above sequence, we get:

436     654     287     543     707

After taking sum of the digits of each of the above numbers, we get

13     15     17     12     14

Here, the number which has the highest sum of digits is 429.

Hence, the correct answer is option C.
4
If 2 is subtracted from each odd digit of each of the given numbers and 1 is added to each even digit of each of the given numbers in the above sequence then what is the difference between the least and the highest numbers?
» Explain it
D
The given sequence:

578     796     429     685     849

Subtracting 2 from each odd digit of each of the given even number of the above sequence and adding 1 to each even digit of each of the given odd number, we get

359     577     537     793     957

The least number: 359
The highest number: 957

The required difference = 957 - 359 = 598

Option D is hence the correct answer.
5
If all the digits within the number are to be added till a single digit number is obtained then how many of these newly formed numbers will be even?
» Explain it
D
The given sequence:

578     796     429     685     849

Adding all the digits within the number till a single digit number is obtained,

20    22    15    19    21

2       4      6      1      3

Here, the total even numbers in the above sequence (highlighted in red) are 3.

Hence, the correct answer is option D.
