About this paper
This is the Indian Air Force Airmen Group X paper for 14 July 2021 (Shift 1), marked 'MBT' (memory-based test) on its cover, so it is a recollection rather than an official question booklet. Its 70 multiple-choice questions run 1–25 Physics, 26–50 Mathematics and 51–70 English, with the correct option printed under each question. Physics covers Carnot engines, electrostatics, inductors, resistance, lenses, Young's double-slit experiment and gas laws; Maths covers integration and areas, probability, sets, permutations, circles, parabolas and matrices. The English part includes a four-question passage on women's empowerment along with spelling, one-word substitution, narration and error spotting. No marks or time limit are printed.
