Miya was playing football in front of the house and was thirsty, so he rushed to the kitchen and took a glass of 1000 cm³ cube in capacity and had it ¾ ful. He looked through the glass and realised that he could see through, but the objects appear bigger and funny too. He then drank all the water from a glass but realised that some water was still left on the walls of the glass and at the bottom and decided to keep the glass open at the top. After his football match, he realised there was no more water in the glass despite the lack of sunlight in the kitchen to dry up the glass.
Which fraction of the glass had water before Miya started drinking.
