When rounded off to nearest thousands, the number $$85642$$ is
Correct option is D. $$86000$$
$$\textbf{Check the digit in the hundreds place:}$$
As we are rounding off the number to the nearest thousands we need to check the digit in the next smaller place value which is hundreds place.
Given number $$= 85642$$
At hundreds places we have $$6$$ which is greater than $$5$$, so we add $$1$$ to the thousand’s place.
Therefore new thousands place will be $$5 + 1 = 6$$
Other digits on the right of the thousand's place will be zeros.
$$\therefore\ 85642$$ rounded off to nearest thousand’s place $$= 86,000$$
$$\therefore$$ $$\textbf{Correct Option is D}$$
