1)The value of 7549 - 3468 - 5065 is
-984
The digit sum of
7549 → 7
3468 → 3
5065 → 7
thus 7549 - 3468 - 5065 → 7 - 3 - 7 → -3 or 6, hence the correct answer will have digit sum as 6 only option B matches i.e. -984, the digit sum of which is -3 or 6
2)The value of 7549 x 3468 x (-5065) is
-132601355580
The digit sum of
7549 → 7
3468 → 3
5065 → 7
thus 7549 x 3468 x (-5065) → 7 x 3 x (-7) → -3 or 6, hence the correct answer will have digit sum as 6 only option A matches i.e. -132601355580, the digit sum of which is -3 or 6
