Hii!
Pratiyogita darpan is a book which is published monthly and is based on the current events in india and across the world on every possible topic. This is helpful for students preparing for government jobs and related competitive exams.
One book costs around INR 30.
The firm also gives options for monthly subscription and home delivery of book each month at a cost of INR 900 to INR 1000 per year plus the postal charges.
Hope this helps.
Good luck!
