According to Census of India 2011, in which state was

I. x² - 4x – 21 = 0

II. y² + 12y + 20 = 0

I. y/16 = 4/y 

II. x³ = (2 ÷ 50) × (2500 ÷ 50) × 4² × (192 ÷ 12)

How many values of x and y satisfy the equation 2x + 4y = 8 & 3x + 6y = 10.

I.  x² = 10                               

II.  y² - 9y + 20 = 0

I. x³ = 1728

II. y² – 15y + 56 = 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

Equation 1: x² - 144x + 5184 = 0

Equation 2: y² - 130y + 4225 = 0

I. √(17x) + √51 = 0   

II. √(4y) + 3 = 0
