Math Problem Statement
when a number is divided by 512 it leaves a reminder 67. If the same number is divided by 32, then what will be the reminder?
Solution
Given that a number when divided by 512 leaves a remainder of 67, we can express this relationship mathematically as: for some integer .
We need to find the remainder when is divided by 32. We start by substituting the expression for into this new division problem:
Since we are dividing by 32, let's consider the expression modulo 32:
We know that: Therefore:
So:
Thus:
Next, we compute: which means:
Therefore:
So, the remainder when the same number is divided by 32 is:
