The position of how many digits in the number 726801 will remain unchanged after the digits within the number are rearranged in descending order (from left to right)?
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → One
Write the digits in descending order and compare the two numbers place by place: a digit keeps its position only if the same digit stands in that place in both numbers.
Given number: 7 2 6 8 0 1
Digits in descending order: 8 7 6 2 1 0
Place by place:
1st: 7 becomes 8
2nd: 2 becomes 7
3rd: 6 stays 6
4th: 8 becomes 2
5th: 0 becomes 1
6th: 1 becomes 0
Only the digit 6 keeps its position.
