hello aspirant,

47.24 score is the percentile that you fetched in your jeemains and your marks would be around 22-30.note that these are based on previous year analysis .As of now its tough to say because the analysis and also cutoffs change every year due to many factors like total students appearing for exam,difficulty level of paper etc.as you did  not mention your category considering you from gen category you wont be eligible to write jee advanced exam.below are the cutoffs to get qualified in jeemains to give jee advanced exam:

Gen category-90-95

gen-ews-70-75

obc ncl-70-75

sc-50-55

st-40-45

pwd-1-2 percentiles.

now according this previous year trends you are not eligible to write jee advanced. and if you dont qualify jeemains you cannot fetch seat in nit,iiits gfits.work hard for upcoming jeemain sessions and improve your score.good luck.for more information refer to: https://engineering.careers360.com/articles/jee-main-cutoff
