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

Equation 1: x² - 45x + 450 = 0

I. 20y² - 13y + 2 = 0

II. 6x² - 25x + 14 = 0

I. 3x² - 16x - 12 = 0

II. 2y² + 11y + 9 = 0

I. 6x² - 23x + 7 = 0

II. 6y² - 29y + 9 = 0

I. 35x² - 46x – 16 = 0

II. 35y² - 116y + 96 = 0

Quantity I: The cash price of a notebook is Rs. 100 but is can also be purchased on 11 monthly equal instalments of Rs. 10 each. Find rate of S.I.?

I. x² – 19x + 88 = 0

II. (y + 4)² = 121

I. x² – 18x + 81 = 0

II. y² – 3y - 28 = 0

I. 6p² – 7p = 5p – 7p² + 25

II. 11q² – 63q + 90 = 0

I. 2x² + 3x - 9 = 0

II. 3y² - y - 10 = 0
