Solution 1
Sure, let's solve this step by step:
-
First, add 4 to each digit of the number 2340124. This gives us 6784568.
-
Next, divide all the even digits by 2. This gives us 3492364.
-
Now, arrange the newly formed number in ascending order. This gives us 2334469.
-
Finally, compare the positions of the digits in the original number (2340124) and the newly formed number (2334469).
The digit 2 retains its position at the first place, the digit 4 retains its position at the third place, and the digit 4 also retains its position at the seventh place.
So, the answer is "Three". Three digits retain their position when the newly formed number is arranged in ascending order.
Solution 2
Sure, let's solve this step by step:
-
First, add 4 to each digit of the number 2340124. The result is 6784568.
-
Next, divide all the even digits by 2. The result is 3492364.
-
Now, arrange the newly formed number in ascending order. The result is 2334469.
-
Finally, compare the positions of the digits in the original number (2340124) and the newly formed number (2334469). The digits that retain their position are 4 and 2.
So, the answer is "Two".
