Detailed Solution

Concept- Its digit at the hundreds place is 0, which also is less than 8, as can be seen from the ones, tens, and hundreds of places, which are 0, 8, and 0. As a result, we must substitute 0 for each of the hundreds as well as tens digits while leaving the other digits in place. The rounded number is helpful for calculations and is also simple to memorise.
Step1: As stated in the question, we will start by determining that the given number, 9080, has a one place of 0, a tens place of 8, and a hundreds place of 0.
Step2: Now that we know that the digit at the hundreds number is 0, which is less than 0, and that we have all the ones, tens, and hundreds of places, which are 0, 8, and 0, we may proceed. As a result, we must substitute each of the hundreds & tens digits with 0 and leave the other digits unchanged.
Step3: Currently, the number in the question is 9080. By rearranging the hundreds, tens, and one's numbers, the result is 9000, but 9100 is closer than 9080.
Hence, the correct answer is option 3.
