Given: (Left) 388 739 783 483 785 (Right)

The highest number is: 785

The first digit of the highest number is: 7 (785)

And, 

The lowest number is: 388

The third digit of the lowest number is: 8 (388)

So, the resultant if the first digit of the highest number is subtracted from the third digit of the lowest number is:

→ 8 - 7 = 1.

The correct answer is "1".

Hence, the correct answer is "Option 4".

Given Numbers: 611, 733, 279, 265, 370

Let's identify the highest and lowest numbers from the given set:

• Highest number: Among 611, 733, 279, 265, 370, the highest number is 733.
• Lowest number: Among 611, 733, 279, 265, 370, the lowest number is 265.

Now, let's extract the required digits:

• The second digit of the highest number (733) is 3.
• The first digit of the lowest number (265) is 2.

Finally, we need to find the resultant if the second digit of the highest number is added to the first digit of the lowest number:

→ 3 + 2 = 5.

The resultant is 5.

Hence, the correct answer is "Option 4".

The logic follows here is :-

Given numbers: 898 740 280 169 993

The highest number is 993.

First digit of the highest number:

• First digit of 993 is 9.

The lowest number is 169.

Then, Third digit of the lowest number:

• Third digit of 169 is 9.

Finally, add the first digit of the highest number to the third digit of the lowest number:

Resultant = (First digit of highest number) + (Third digit of lowest number)

Resultant = 9 + 9

Resultant = 18

Hence, the correct answer is "Option 4".

The logic follows here is :-

Given numbers: 773 263 387 270 378

The lowest number is 263.

Now, extract the first digit of the lowest number:

• First digit of 263 is 2.

The highest number is 773.

Then, extract the first digit of the highest number:

• First digit of 773 is 7.

Finally, subtract the first digit of the lowest number from the first digit of the highest number:

Resultant = (First digit of highest number) - (First digit of lowest number)

Resultant = 7 - 2 = 5

Hence, the correct answer is "Option 1".

The given three-digit numbers are: 210, 878, 407, 692, 140.

Now,

The highest number is 878. Its third digit is 8.

The lowest number is 140. Its first digit is 1.

Perform the subtraction.

Subtract the third digit of the highest number 8 from the first digit of the lowest number 1.

1 - 8 = -7.

Hence, the correct answer is "Option 1".

Given 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.

Given: (Left) 567 243 186 689 427 (Right)

According to the given information, we have 

Second greatest number = 567 ⇒ First digit = 5

Smallest number = 186 ⇒ Third digit = 6

Next, adding the first digit and the third digit = 5 + 6 = 11

Thus, the result will be 11.

Hence, the correct answer is 'option 2'.

Given: 

(left) 434 353 423 224 322 (right)

After 4 is added to the second digit of every number we will get,

(left) 474 393 463 264 362 (right)

Let us check whether the second digit is exactly divisible by the third digit of the number thus formed or not:

474 ⇒ 7 ÷ 4 ⇒ (Not divisible).

393 ⇒ 9 ÷ 3 = 3 (Divisilbe).

463 ⇒ 6 ÷ 3 = 2 (Divisible).

264 ⇒ 6 ÷  4 ⇒ (Not divisible).

362 ⇒ 6 ÷ 2 = 3 (Divisible).

Thus, there are only three such numbers whose second digit is exactly divisible by the third digit.

Hence, the correct answer is 'Three'.

Given numbers: 378 256 431 875 762

On adding 2 to the second digit: 398 276 451 895 782

On arranging the numbers in descending order: 895 782 451 398 276

451 is the third-lowest number and the corresponding number of that in the actual series is 431

Hence, 451 is the third lowest number which is obtained from 431.

Given series: 483         396      625      834      967

Series each number is multiplied by 2: 966    792      1250    1668    1934

Lowest number is = 792

And 1st digit of the lowest = 7,

Largest number is = 1934.

Last digit of largest number is = 4

Multiplication = 7 × 4 = 28

Hence, 28 is correct answer.

Given numbers:

654 483 635 928 519

On subtracting 2 from the given numbers, we get: 652 481 633 926 517

Hence, only one number i.e., 633 is a multiple of 3 which is obtained from 635.

The logic follows here as is,

• Logic: 3rd number = 1st number + (2nd number ÷ 2)

(i): 3rd number = 13 + (16 ÷ 2) = 13 + 8 = 21

(ii): 3rd number = 28 + (34 ÷ 2) = 28 + 17 = 45

Apply the logic on the options,

Option 1: (37,18, 46)

3rd number = 37 + (18 ÷ 2) = 37 + 9 = 46 (true)

Option 2: (72, 45, 27)

3rd number = 72 + (45 ÷ 2) = 72 + 22.5 = 94.5 (false)

Option 3: (64, 26, 90)

3rd number = 64 + (26 ÷ 2) = 64 + 13 = 77 (false)

Option 4: (35, 12, 59)

3rd number = 35 + (12 ÷ 2) = 35 + 6 = 41 (false)

Here, the logic applies only to option 1.

Hence, 'option 1' is correct.

In the given series:-

429 738 273 894 156

When the first two digits are reversed for every number, the number becomes:-

249 378 723 984 516

The highest and the lowest number of this series are 984 and 249 respectively.

The difference between the first digit of these two numbers is = 9 - 2 = 7.

Hence, "option 4" is the correct answer.

Given numbers:

243      342      573      452      621

On interchanging the first and second digits of the numbers, we get

423      432      753      542      261

Hence, the smallest number is 261, which we get from 621.

Hence, 621 is the correct answer.

Given Series: 758      839      246      197      564

Odd numbers: 839, 197

Even numbers: 758, 246, 564

On adding 1 to the first digit of odd numbers and 2 to the first digits of even numbers: 958      939      446      297      764​

Here, in 939 and 446 the digits are repeating more than once.

Hence, the answer is 'Two'.
