i think copy paste in NCERT soulution should be enabled for the users who have paid...it will be easier for us to print the answers given by meritnation instead of keep opening the laptop to see the answers and getting distracted by other sites.

We are completely aware of the problems faced by you and our other students in this concern. However, we are in a process of regular updation of the content in order to make it more useful for you. As a result, we have presently disabled the 'copy' feature. For the time being, you can take the screenshots of the solutions for taking printouts and also for later use. For taking screenshots hit the PRTSC button available on the top right side of your keyboard, then open Paint option from Accessories, use ctrl+v command and save the file.
