Each of the digits in the number 7148356 is arranged in ascending order from left to right. The position of how many digits will remain unchanged as compared to that in the original number?
✓ Correct answer: b) One
ExplanationThe original number is 7148356. To solve this, we first arrange the digits in ascending order: 1, 3, 4, 5, 6, 7,8. Now, let's compare the original number with the new arrangement: Original: 7, 1, 4, 8, 3, 5, 6 Sorted: 1, 3, 4, 5, 6, 7, 8 We'll check the positions: The first digit, 7, moves to the 6th position.The second digit, 1, moves to the 1st position.The third digit, 4, moves to the 3rd position (unchanged).The fourth digit, 8, moves to the 7th position.The fifth digit, 3, moves to the 2nd position.The sixth digit, 5, moves to the 4th position.The seventh digit, 6, moves to the 5th position.Thus, the digit that remains in the same position is4. So, the number of digits, the position of which remains unchanged in position is one.Hence, one is the correct answer.
