Question

Round off 7065 to nearest 1000:
$
  {\text{A}}{\text{. 700}} \\
  {\text{B}}{\text{. 7000}} \\
  {\text{C}}{\text{. 70}} \\
  {\text{D}}{\text{.7}} \\
 $

Answer 1

Hint: To solve this question we have to Compare 065 with 500. Because We know the rules of rounding off, that is if we have a two digit number we compare with 5 and when we have a number approx 100 we compare with 50 for rounding off as like here we have to round off to the nearest 1000 so we will compare with 500.

Complete step-by-step answer:
Because round off to the nearest 1000 is asked we check the digits till place value 100 i.e. one place value less than that asked in question.
So, the last 3 digits are compared with 500.
Because ( 065 < 500) , all the last 3 digits are replaced with 0s.
So the round off becomes 7000.
The correct option is (B).

NOTE: If the last 3 digits had been greater than 500 then: The last 3 digits would be replaced by 0 and 1 would be added to the digit at the thousands place value.
