We know that opposite charges attract each other. but ,in the study material it is given that some rays were travelling in the opposite direction of cathode rays , called anode rays.
Why is it so?

Solution

Anode ray are positively charged.

As opposite charged attract toward each other, they move towards negatively charged plate (cathode), which is opposite to cathode rays.
