In the question, two equations I and II are given. You have to solve both the equations to establish the correct relation between x and y.

I. 6x² - 13 x + 6 = 0

II. 15 y² + 11 y - 12 = 0

Solve: x² − 7x + 12 = 0

I. 2x² - 9 x + 9 = 0

II. 2y² - 7 y + 3 = 0

I. 10x² + 33x + 9 = 0

II. 2y² + 13y + 21 = 0

The roots of the equations x² + 16x + 63 = 0

I.8^(x+3) +  8^(-x) =72 

II. 5^{(y + 5)} + 5^(-y) = 150 

I. x² + 91 = 20x

II. 10y² - 29y + 21 = 0

I. p² - 53p + 672 = 0

II. q² - 27q + 126  = 0

Quantity I: The price of rice is decreased by 30%, by how much % the consumption is increase so that the expenditure will decreased by 10%?
