Hello Aspirant,

See it is quite difficult to help you out with the exact number of questions coming from any particular because it can change as per the total marks of the paper which which is subject to change every year but yes we can help you out with the approximate weightage of Algebra part in JEE-Advance on the basis of previous years analysis so if you are considering only for algebra without wither differential or integral calculus then it will take around 11-12% total weightage in paper of JEE-Advance. From Algebra you have to prepare some important topics such as Algebra of complex numbers, addition, multiplication, conjugation, polar representation, properties of modulus and principal argument, triangle inequality, cube roots of unity, geometric interpretations, Quadratic equations with real coefficients, relations between roots and coefficients, formation of quadratic equations with given roots, symmetric functions of roots. Arithmetic, geometric and harmonic progressions, arithmetic, geometric and harmonic means, sums of finite arithmetic and geometric progressions, infinite geometric series, sums of squares and cubes of the first n natural numbers. Logarithms and their properties, Permutations and combinations, binomial theorem for a positive integral index, properties of binomial coefficients.
