If 3 is subtracted from the middle digit of each of the following numb...
To solve this problem, we need to follow the given steps:
Step 1: Subtract 3 from the middle digit of each number.
Step 2: Reverse the positions of the digits in each number.
Step 3: Arrange the numbers in descending order.
Step 4: Determine the last digit of the middle number.
Let's apply these steps to the given numbers:
589:
Step 1: Subtract 3 from the middle digit (8) = 5 8 - 3 = 5 5
Step 2: Reverse the positions of the digits = 5 5
Step 3: No other numbers to compare, so 5 5 is the first number.
Step 4: The last digit of the middle number is 5.
362:
Step 1: Subtract 3 from the middle digit (6) = 3 6 - 3 = 3 3
Step 2: Reverse the positions of the digits = 3 3
Step 3: Compare with previous number(s) = 5 5 > 3 3, so 3 3 comes after 5 5.
Step 4: The last digit of the middle number is 3.
554:
Step 1: Subtract 3 from the middle digit (5) = 5 5 - 3 = 5 2
Step 2: Reverse the positions of the digits = 2 5
Step 3: Compare with previous number(s) = 5 5 > 2 5, so 2 5 comes after 5 5.
Step 4: The last digit of the middle number is 2.
371:
Step 1: Subtract 3 from the middle digit (7) = 3 7 - 3 = 3 4
Step 2: Reverse the positions of the digits = 4 3
Step 3: Compare with previous number(s) = 5 5 > 4 3, so 4 3 comes after 5 5.
Step 4: The last digit of the middle number is 4.
442:
Step 1: Subtract 3 from the middle digit (4) = 4 4 - 3 = 4 1
Step 2: Reverse the positions of the digits = 1 4
Step 3: Compare with previous number(s) = 5 5 > 4 1, so 1 4 comes after 5 5.
Step 4: The last digit of the middle number is 1.
Now, let's arrange the numbers in descending order based on their first digits:
589 > 554 > 442 > 371 > 362
The last digit of the middle number after arranging them in descending order is 2.
Therefore, the correct answer is option 'C' - 2.
Step 1: Subtract 3 from the middle digit of each number.
Step 2: Reverse the positions of the digits in each number.
Step 3: Arrange the numbers in descending order.
Step 4: Determine the last digit of the middle number.
Let's apply these steps to the given numbers:
589:
Step 1: Subtract 3 from the middle digit (8) = 5 8 - 3 = 5 5
Step 2: Reverse the positions of the digits = 5 5
Step 3: No other numbers to compare, so 5 5 is the first number.
Step 4: The last digit of the middle number is 5.
362:
Step 1: Subtract 3 from the middle digit (6) = 3 6 - 3 = 3 3
Step 2: Reverse the positions of the digits = 3 3
Step 3: Compare with previous number(s) = 5 5 > 3 3, so 3 3 comes after 5 5.
Step 4: The last digit of the middle number is 3.
554:
Step 1: Subtract 3 from the middle digit (5) = 5 5 - 3 = 5 2
Step 2: Reverse the positions of the digits = 2 5
Step 3: Compare with previous number(s) = 5 5 > 2 5, so 2 5 comes after 5 5.
Step 4: The last digit of the middle number is 2.
371:
Step 1: Subtract 3 from the middle digit (7) = 3 7 - 3 = 3 4
Step 2: Reverse the positions of the digits = 4 3
Step 3: Compare with previous number(s) = 5 5 > 4 3, so 4 3 comes after 5 5.
Step 4: The last digit of the middle number is 4.
442:
Step 1: Subtract 3 from the middle digit (4) = 4 4 - 3 = 4 1
Step 2: Reverse the positions of the digits = 1 4
Step 3: Compare with previous number(s) = 5 5 > 4 1, so 1 4 comes after 5 5.
Step 4: The last digit of the middle number is 1.
Now, let's arrange the numbers in descending order based on their first digits:
589 > 554 > 442 > 371 > 362
The last digit of the middle number after arranging them in descending order is 2.
Therefore, the correct answer is option 'C' - 2.

If 3 is subtracted from the middle digit of each of the following numb...
On subtracting 3 from the middle digit the numbers become
559, 332, 524, 341, 412
Now reverse the positions of digits,
955, 233, 425, 143, 214
Arranging the above numbers in descending order, we get
Hence 3 is the required number.
559, 332, 524, 341, 412
Now reverse the positions of digits,
955, 233, 425, 143, 214
Arranging the above numbers in descending order, we get
Hence 3 is the required number.
