Answer (Detailed Solution Below)
Group Based Question 1 Detailed Solution
Given: 687 465 774 381 452
According to the question:
| Given numbers | 687 | 465 | 774 | 381 | 452 |
| 2 is added to the middle digit of each number | +2 | +2 | +2 | +2 | +2 |
| Resultant numbers | 707 | 485 | 794 | 401 | 472 |
| The position of the digits are reversed | 707 | 584 | 497 | 104 | 274 |
| Number arranged in ascending order | 104 | 274 | 497 | 584 | 707 |
Thus, the last digit of the middle number is → 497 → 7
Hence, "Option 1" is the correct answer.
Group Based Question 2:
This question is based on the five, three-digit numbers given below.
(Left) 271 415 612 872 547 (Right)
(Example- 697 – First digit = 6, second digit = 9 and third digit = 7) (NOTE: All operations to be done from left to right.)
If all the numbers are arranged in descending order, the position(s) of how many numbers will remain unchanged?
Answer (Detailed Solution Below)
Group Based Question 2 Detailed Solution
Given numbers: '271 415 612 872 547'
After arranging in descending order:
| Original Position | 1st | 2nd | 3rd | 4th | 5th |
| Original Numbers | 271 | 415 | 612 | 872 | 547 |
| Descending Order | 872 | 612 | 547 | 415 | 271 |
Now,
There are no numbers that will remain unchanged if all the numbers are arranged in descending order.
Hence, the correct answer is "Option 3".

added to the second digit of the lowest number?
Answer (Detailed Solution Below)
Group Based Question 4 Detailed Solution
Given: (Left) 284 452 371 372 763 (Right)
The third digit of the highest number is: 3 (763)
And,
The second digit of the lowest number is : 8 (284)
So, the addition of the third digit of the highest number and the second digit of the lowest number is:
→ 3 + 8 = 11.
The correct answer is "Option 1".

(Left) 164 253 927 834 519 (Right)
(Example- 697 - First digit = 6, second digit = 9 and third digit = 7)
NOTE: All operations to be done from left to right.
If 2 is added to second digit of every number, in how many numbers will the second digit be exactly divisible by the first digit?
Answer (Detailed Solution Below)
Group Based Question 5 Detailed Solution
Given: (Left) 164 253 927 834 519 (Right)
According to the question:
| Given numbers | 164 | 253 | 927 | 834 | 519 |
| 2 is added to the second digit of every number | +2 | +2 | +2 | +2 | +2 |
| Resultant numbers | 184 | 273 | 947 | 854 | 539 |
| If the second digit be exactly divided by the first digit of that number | 8 ÷ 1 | 7 ÷ 2 | 4 ÷ 9 | 5 ÷ 8 | 3 ÷ 5 |
| Required answer | 8 ⇒ Divisible | Not divisible | Not divisible | Not divisible | Not divisible |
Thus, according to the final arrangement, in only one number will the second digit be exactly divided by the first digit of that number.
Hence, "Option 4" is the correct answer.

Group Based Question 6 Detailed Solution
Download Solution PDFGiven 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.Comprehension:

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.This question is based on the five, three-digit numbers given below.
(left) 434 353 423 224 322 (right)

If 4 is added to the second digit of every number, in how many numbers thus formed will the second digit be exactly divisible by the third digit?
Answer (Detailed Solution Below)
Group Based Question 8 Detailed Solution
Download Solution PDFGiven:
(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'.

Answer (Detailed Solution Below)
Group Based Question 9 Detailed Solution
Download Solution PDFGiven: (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'.
