Correct option is C
Logic:
First position: subtract 1 from the digit.
Second position: square the digit.
This alternates for the rest of the digits.
Let’s analyze the example provided:
618293 is written as 517489.
1st position: 6 → 6 - 1 = 5
2nd position: 1 → 1² = 1
3rd position: 8 → 8 - 1 = 7
4th position: 2 → 2² = 4
5th position: 9 → 9 - 1 = 8
6th position: 3 → 3² = 9
Now, let's apply the same logic to 437251:
1st position: 4 → 4 - 1 = 3
2nd position: 3 → 3² = 9
3rd position: 7 → 7 - 1 = 6
4th position: 2 → 2² = 4
5th position: 5 → 5 - 1 = 4
6th position: 1 → 1² = 1
Thus, 437251 will be written as 396441.
Correct answer is (c) 396441.
