Read the directions carefully and answer the following

What is the average salary of 10 officers , if a clerk’s salary is Rs. 15,000?

I. 6x² + 19x + 10 = 0

II. y² + 10y + 25 = 0

I. 2y²+ 13y + 15 = 0

II. 2x²+ 11 x + 12 = 0

I. 5x² = 19x – 12

II. 5y² + 11y = 12

l).  2p² + 12p + 18 = 0 

ll).  3q² + 13q + 12 = 0

I. 2x² - 9x + 10 = 0

II. 3y² + 11y + 6 = 0

Solve the quadratic equations and determine the relation between x and y:

Equation 1: x² - 29x + 210 = 0

Equation 2: y² - 27y + 182 = 0

I: x² - 10x + 21 = 0  

II: 4y² - 16y + 15 = 0

I. (2x-3)³+  1/((2x-3)³)=2 

II.   4y²+(y+8)^2= 157

I. 3x² - 16x - 12 = 0

II. 2y² + 11y + 9 = 0
