Question

when a number is being divided by 27 the remainder obtained is 17. what will be remainder if the same number is divided by 9​

Answer 1

Answer:

Let the number be N, and quotient be n

Since when we divided a certain number by 48, we get a remainder 31,

We have N = 48(n) + 31 where 'n' is the quotient got by dividing number by 48

We can write

N=24×2×n+31

=24×(2n)×24+7

=24(2n+1)+7

So, when we divide N by 24, remainder left is 7
