It is a MCQ maths book for class 9. It was written by the infamous R.D. Sharma. This will help to do better in exams. This is necessary if you want to excell in maths. This will help to do maths more fast, specially the MCQs. It's actual cost is rs. 545 but as it was only bought by me ( *NOT USED* (There may be some folds,otherwise it is completely UNUSED and NEW))
