Bose Olympiad Senior Level: Resources

Bose Olympiad Senior is suitable for kids in Grade 8 and above.

Curriculum

  • Number Theory
  • Combinatorics
  • Algebra
    • Polynomials
    • Complex Numbers
    • Inequality
  • Geometry

Number Theory

The following topics in number theory are useful for the Senior round:

  • Bezout’s Theorem and Euclidean Algorithm
  • Theory of congruence
  • Number Theoretic Functions
  • Theorems of Fermat, Euler, and Wilson
  • Pythagorean TriplesChinese Remainder Theorem

Here is an example of a Number Theory problem that may appear in Seinor Bose Olympiad:

Suppose a, b, c are the side lengths of an integer sided right-angled triangle such that GCD(a, b, c) = 1. If c is the length of the hypotenuse, then what is the largest value of the GCD (b, c)?

Key idea: Pythagorean Triples

Geometry

The following topics in geometry are useful for the Senior Bose Olympiad round:

  • Synthetic geometry of triangles, circles
  • Barycentric Coordinates
  • Miquel Point Configuration
  • Translation
  • Rotation
  • Screw Similarity

Here is an example of a geometry problem that may appear in the Senior Bose Olympiad:

Suppose the river Basumoti is 25 meters wide and its banks are parallel straight lines. Sudip's house 10 meters away from the bank of Basumoti. Apu's house is on the other side of the river, 15 meter away from the bank. If you are allowed to construct a bridge perpendicular to the banks of Basumoti, what is the shortest distance from Sudip to Apu's house.

Key idea: Reflection

Algebra

The following topics in Algebra are useful for Intermediate Bose Olympiad:

  • Screw similarity, Cyclotomic Polynomials using Complex Numbers
  • AM, GM, and Cauchy Schwarz Inequality
  • Rational Root Theorem, Remainder Theorem
  • Roots of a polynomial

Here is an example of an algebra problem that may appear in Senior Bose Olympiad:

The following sum is greater than which integer:

    \[\frac{2}{3} + \frac{3}{4} \cdots + \frac{2019}{2020} + \frac{2020}{2}\]

(A) 2019 (B) 2020 (C) 2021 (D) 2022

Key idea: inequality
