QUESTION: 21

**Directions: Study the following numbers carefully and answer the questions given beside:**

867 495 736 592 619

**Q. **If the position of first and second digit of each number are to be interchanged within the number then what would be the sum of the highest and second highest number thus obtained?

Solution:

The given sequence:

867 495 736 592 619

Interchanging the position of first and second digit of each number, we get:

687 945 376 952 169

Highest number = 952

Second highest number = 945

Required Sum = 952 + 945 = 1897

QUESTION: 22

**Directions: Study the following numbers carefully and answer the questions given beside:**

867 495 736 592 619

**Q. **Which of the following values will be obtained if the highest digit of the lowest number is added to the sum of the highest and lowest digits of the highest number?

Solution:

The given sequence:

867 495 736 592 619

Here, the lowest number = 4**9**5 and the highest digit in it is 9.

And, the highest number = **86**7 in which the highest and lowest digits are 8 and 6 respectively.

Required Sum = 9 + 8 + 6 = 23

QUESTION: 23

**Directions: Study the following numbers carefully and answer the questions given beside:**

867 495 736 592 619

**Q. **If all the digits are to be arranged in increasing order from left to right within the number then what will be the difference between the highest number and the lowest number thus obtained?

Solution:

The given sequence:

867 495 736 592 619

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

678 459 367 259 169

Highest number = 678

Lowest number = 169

Required Difference = 678 – 169 = 509

QUESTION: 24

**Directions: Study the following numbers carefully and answer the questions given beside:**

867 495 736 592 619

**Q.** If 1 is subtracted from each odd digit of each of the numbers first and then each perfect square digit is changed into 5, what is the sum of the least and the greatest number in the sequence thus obtained?

Solution:

The given sequence:

867 495 736 592 619

Subtracting 1 from each even digit of each of the numbers:

866 484 626 482 608

Changing every perfect square digit into 5, we get:

866 585 626 582 608

The sum of the least and the greatest number:

582 + 866 = 1448

QUESTION: 25

**Directions: Study the following numbers carefully and answer the questions given beside:**

867 495 736 592 619

**Q. **If all the odd numbers in the sequence are written in a reverse order and then placed in descending order, which of the following numbers will be the second from the right end of the sequence?

Solution:

The given sequence:

867 495 736 592 619

Writing all the odd numbers in a reverse order, we get

768 594 736 592 916

The final sequence of numbers in descending order:

916 768 736 594 592

Hence, the second number from the right end will be: **594**
