Thus. the number on the face opposite the face showing 2 is 5.
A cylinder is painted in 6 colours - Green, Blue, Yellow, Violet, Red and Pink. Three positions are shown below.
What is the colour in the empty space?
If you look carefully on the images given of the cylinder, you will observe that the cylindrical bases have Pink and Yellow colours.
The colours on the curve of the cylinder are Green, Blue, Red and Violet.
Green and Blue colours are together, so Red and Violet will be together.
Hence, the colour in the empty space is Violet.
