- 02
31% of its questions since 2020 tested an idea no earlier year had asked; 73 repeated an idea from the year before.
- 03
The most repeated idea is Combinations of Distinct Objects, asked 16 times in 16 shifts (2017, 2020, 2021, 2022, 2023, 2024, 2025, 2026), most often as “ways to win a series”.
- 04
JEE Main has asked 33 of the 60 ideas in this topic; 24 have never been asked, directly or inside another question.
- 05
Mostly asked as numerical value (52%); 52% need a numerical answer, 18% are easy and 18% hard.
- 06
The skill tested most is multi-step (43%), then calculation (36%).
Questions a shift, year by year
Out of the 25 Maths questions in a shift. Years differ in how many shifts Lumi analysed, so each year is scaled to one shift.

New idea, or one asked before?
Each column is a year. Blue questions tested an idea no earlier year had asked; navy ones went back to an idea from an earlier year. 2017 is the first year, so everything in it counts as new. Heights are question counts, and Lumi analysed 1 to 24 shifts a year, so compare the split inside a column rather than heights across years.
- Idea asked for the first time
- Idea asked in an earlier year
Coverage of the topic
JEE Main has asked 33 of the 60 ideas in this topic. 24 have never been asked yet.

Squares are the 8 years with analysed shifts, 2017 to 2026. A number is the questions that year when there is more than one; the shade is scaled to one shift, so a year with more analysed shifts (1 to 24 a year) does not look darker. Share is of the level above.
