Question

Arrange the Following Numbers in Descending Order:

$5000,7500,85400,7861$

Answer 1

Methodology to compare numbers:

There are two cases:

Case $\mathrm{I}$: When the numbers to be compared have different number of digits, a number containing more digits excluding $0$ at leftmost position represents a greater number.

Case $\mathrm{II}$: When numbers to be compared have the same number of digits then that number, which has a greater leftmost digit, is larger. If this digit also happens to be the same, we look at the next digit and so on.

Therefore, the descending order of digits is: $85400>7861>7500>5000$
