Sir maths class 10 ke liye refrence book lani chahiae ya sample paper questions sir please bataiye ki konse lani chahiae.

[@AviJainClasses]

R D sharma, Monica kapoor as refreshers .... and P.K.Garg where you can get a collection of all the questions at a place .... Sample papers include the latest questions which these books might not include.... So, we can’t substitute one for another..... If you’ll ask me for one name - I would go for “monica kapoor”
