Are these solutions based on the current 2026-27 NCERT syllabus?

Yes — this covers the rationalised Chapter 1 (Real Numbers) as currently prescribed by NCERT for the 2026-27 academic session, matching the two-exercise structure (Exercise 1.1 on prime factorisation/HCF-LCM, and Exercise 1.2 on proving irrationality) introduced after the 2023 syllabus rationalisation.

Is Chapter 1 important for the CBSE Class 10 board exam?

Yes. Real Numbers is a compact chapter that consistently appears in board papers, usually as a 2–3 mark proof or HCF/LCM application question, making it high value relative to the small amount of content it covers.
