A standard form of quadratic equation ax2 + bx + c = 0, (a ≠ 0). Quadratic arithmetic solutions (real roots only) with factorization, as well as using quadratic formula. The relationship between prejudice and the root environment. Status problems based on quadratic statistics related to daily activities (statistical problems being reduced to quadratic statistics are not included)



2. THE CONTINUATION OF ARITHMETIC


Inspiration for Arithmetic Progression The issuance of the nth term and the sum of the first terms n of A.P. and its effectiveness in solving everyday life problems. (Applications based on the amount to the principles of A.P. are not included)

UNIT- GEOMETRY

PARTNERSHIP IN MATHEMATICS

PARTNERSHIP

QUESTION 1.  A,B and C  started a business by investing Rs.1,20,000,Rs 1,35,000 and Rs. 1,50,000 respectively.Find the share of each, out of annual profit of Rs.56,700.

SOL.
Ratio of shares of A,B and c=120000:135000:150000=8:9:10
sum=8+9+10=27
A’s share=8/27*56700=16800
B’s share=9/27*56700=18900
C’s share=10/27*56700=21000.
