The value 92, 45 how it comes.

Explain.

To find the correct no to add in amt 1056 it is divided by 23 to like 23*4 = 92 & its minus from 1056 then it remains 136 then its divided by 23*5 = 115 & minus from 136 then the remaining amt is 21 so there must be add 2 no.(21+2=23) so the ramaining amt will be zero.

1056/23=45.91
23*45=1035
1056-1035=21

Therefore 23-21=2
Ans =2
(1)

It is so easy..

If the number 1056 is completely divisible by 23 means, remainder should come zero..

But if we divide 1056 by 23, the remainder is 2..

So if 2 is added to the 1056, we get remainder 0.

Therefore solution is 2
