Which book by Ml khanaa is preferred for jee ?Iit maths or objective maths?

YOU CAN USE OBJECTIVE MATHEMATICS FOR QUESTION SOLVING AS IT CONTAINS VERY GOOD QUESTIONS WHICH ARE IMPORTANT FOR JEE ADVANCE EXAM. 

ALONG WITH IT YOU CAN REFER TO NCERT EXEMPLAR BOOK AS IT IS ALSO A VERY IMPORTANT BOOK WHICH STUDENTS GENERALLY IGNORE

@ shuhaibks 
if u have more time then go for iit maths as it have explained shortcuts as well as the required theory in precise manner , but if less time , then objective maths are preferrable . 

so, check if u can complete iit maths within time , if u thinks then go with that , else , objective maths are good for problem solving 
ALL THE BEST ..
