Per NCERT, which approximate value did BRAHMAGUPTA (628 CE) suggest for π — chosen for mathematical elegance even though slightly less accurate?
A355/113
B3.0 exactly
C22/7
D√10 ≈ 3.1622
Answer & Solution
Correct answer: D. √10 ≈ 3.1622
Brahmagupta proposed √10 (per NCERT), valued for algebraic elegance. The other approximations come from other mathematicians.
