**Question 1**

What will be the largest number when the position of the first and the second digit within each of the given numbers are interchanged?

a) 549 b) 369 c) 827 d) 453 e) 968

**Answer : **e) 968

Solution :

Given numbers: 549, 369, 827, 453, 968

After interchanging the first and second digit, the numbers are:

549 -> 459

369 -> 639

827 -> 287

453 -> 543

968 -> 698

Therefore, the highest number is 698 and its corresponding number is 968.

Hence the answer is option e.

**Question 2**

What will be the sum of the first and last digit of the smallest number if the position of the first and last digit within each of the given number is interchanged?

a) 14 b) 12 c) 15 d) 7 e) 17

**Answer :** d) 7

Solution :

Numbers after interchanging first and last digit are,

549 -> 945

369 -> 963

827 -> 728

453 -> 354

968 -> 869

Now the smallest number is 354 and the sum of first and last digit is 3 + 4 = 7.

**Question 3**

Which of the following will be the second digit of the second lowest number when 7 is added to each of the given five numbers?

a) 6 b) 7 c) 3 d) 8 e)5

**Answer : **a) 6

Solution:

After adding 7 to each of them, they become:

549 + 7 = 556

369 + 7 = 376

827 + 7 = 834

453 + 7 = 460

968 + 7 = 975

Second lowest number is 460.

And required second digit is 6.

**Question 4**

Find the last digit of the middle number, when 3 subtracted from the first digit and added to the second digit of each of the given five numbers.

a) 7 b)9 c) 1 d) 6 e) 3

**Answer : **b)9

Solution:

Given numbers: 549, 369, 827, 453, 968

After adding 3 to the second digit and subtracting 3 from first digit, they become:

549 -> 279

369 -> 099

827 -> 557

453 -> 183

968 -> 698

In ascending order: 99, 183, 279, 557, 698

Therefore, the middle number is 279.

Last digit of the middle number is 9.
