Answer 1

Just difficulty level of question paper in 10th boards will be different, syllabus for both maths is same

If you opt standard maths in 10th class then you option for any subject of your choice in 11th class

And if you choose basic maths then you can not have maths as a main subject in 11th

There is also an option if you choose basic maths and want to opt maths then you have to appear for reexam for standard maths after result
