Second highest number: 645
Its 2nd digit = 4
Highest number: 843
Its 3rd digit = 3
Clearly, the resultant = 4 × 3 = 12
Hence, Option B is correct.

MCQ Test: Alphanumeric Series - 2 - Question 12

Directions: The following are based on the five three-digit numbers given below:
 
645     172     843     241     463     571

Q: If all the digits in each of the numbers are arranged in descending order within the number, which of the following numbers given in the original sequence will become the lowest number in the new arrangement?

Detailed Solution: Question 12

Given sequence:
645     172     843     241     463     571
New sequence:
654     721     843     421      643     751

New sequence:
644   174     842     240     462     570
We know that a number is divisible by 3 if the sum of its digits is also divisible by 3. 
Following this, we can observe that the numbers '174', '240', '462' and '570' are divisible by 3.
Hence, Option B is correct.

MCQ Test: Alphanumeric Series - 2 - Question 14

Third highest number: 571
Its 2nd digit = 7
Lowest number: 172
Its 3rd digit = 2
Clearly, the resultant difference = 7 – 2 = 5
Hence, Option B is correct.

MCQ Test: Alphanumeric Series - 2 - Question 15

Directions: The following are based on the five three-digit numbers given below:
 
645     172     843     241     463     571

Detailed Solution: Question 16

The given numbers:
253         883         535         738         467
Arranging all the digits in each of the numbers are arranged in ascending order within the number, we have:
235         388         355         378         467
Hence, 253 becomes the lowest number.
Hence, the correct answer is option A.

MCQ Test: Alphanumeric Series - 2 - Question 18

Directions: The following questions are based on the three digit numbers given below:
 
253  883   535   738   467

Q: What will be the resultant if the third digit of lowest number and the first digit of second lowest number are multiplied?

Detailed Solution: Question 18

The given numbers:
253         883         535         738         467
Arranging the given number in the ascending order, we have:
253         467         535         738         883
The third digit of lowest number = 3
The first digit of second lowest number = 4
Now, we can multiply 3 and 4, as per the question and we have:
3 × 4 = 12
Hence, the correct answer is option D. 

MCQ Test: Alphanumeric Series - 2 - Question 19

Directions: The following questions are based on the three digit numbers given below:
 
253  883   535   738   467

Q: What will be the resultant if the first digit of the second lowest number divides the second digit of the highest number?

Detailed Solution: Question 19

The given numbers:
253         883         535         738         467
Putting all the number in ascending order, we have:
253         467         535         738         883
The first digit of the second lowest number = 4
The second digit of the highest number = 8
The resultant = 8/4 = 2
Hence, the correct answer is option A.

MCQ Test: Alphanumeric Series - 2 - Question 20

Directions: The following questions are based on the three digit numbers given below:
 
253  883   535   738   467

Q: If 2 is added to the first digit of every even number and 3 is subtracted from the third digit of every odd number, then in how many numbers will a digit appear twice?

Detailed Solution: Question 20

The given numbers:

253         883         535         738         467

As per the question, we would have new numbers as:

253 → 250          
883 → 880          
535 → 532          
738 → 938          
467 → 464

Here, we can easily see that there are two such numbers in which a digit appear twice. Hence, the numbers are 880 and 464

Hence, the correct answer is option B.
