(y * dā€™) % wā€™ = pā€™ % wā€™
then let us take dā€™ % wā€™ as dā€™ā€™ (or d2)
this equation the becomes
y * dā€™ā€™ = pā€™ā€™
which becomes
y = pā€™ā€™/dā€™ā€™ or y = pā€™ā€™ * (dā€™ā€™)^-1

we should even chage y to yā€™

y is less than w
So y%w = y = yā€™

@leoking ā€¦i hope you are in confusion. If you read the question , you can find out that there is a pre-condition i.e, y>=w

@fake.one720 Can you please explain how you got y>=w ? I am not getting this part.
