It is 2000.Most schools wrongly teach you to always round 5 (in this case, 50) up so the answer would be 2100 but, while this is a simple rule to teach, it is not really correct. Under this rule:• if the following digit is 0 you don't round;• if the following digit is 1, 2, 3 or 4 you round down; and• if the following digit is 5, 6, 7, 8 or 9 you round up.As a result you are more likely to round up than round down and that introduces an upward bias into your calculations.The IEEE (Institute of Electronic and Electrical Engineers) standard 754 is to round 5 up or down so that the new last digit is even.

It is 800.
When you round off 42 754 to the nearest thousands, you will have 40 000, and to ten thousands, you get 0.

False.Many schools do teach you to round 5 up, always rounding up from 5 is inappropriate because it introduces an upward bias. The IEEE (Institute of Electronic and Electrical Engineers) standard 754 is to round 5 up or down so that the new last digit is even.

39.5, 40.5 (to the nearest unit) 35 and 45 (to the nearest 10) 31 and 59 (to the nearest 20). Rather than round up 5s, I "round ties to even". This is the recommended default under the IEEE 754 technical standard which has been adopted internationally.
The tens' digit is 6. If what follows it is less than 5 then replace every digit following the tens' digit by 0s. If what follows is bigger than 5 then add 1 to the tens' digit and replace every digit following the tens' digit by 0s. If it is exactly 5 then make sure that the tens' digit is even and replace everything after it by 0s. Many naive teachers require that you round up (add 1 etc) when the next digit is 5. This introduces an upward bias and in statistically unsound. The solution is to round to odd or round to even. (See link). Mathematically, they are equivalent but, judging by the latter seems to be winning. It is the default mode in IEEE 754.
