What percentage of India’s GDP did gross fixed capital

I. y/16 = 4/y 

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

I: x² + 31x + 228 = 0

II: y² + 3y – 108 = 0

I. 5q = 7p + 21

II. 11q + 4p + 109 = 0

The roots of x² − (k+3)x + (3k − 1) = 0 are real and distinct, and the larger root exceeds the smaller by 5. Find k.

I. 64x² - 64x + 15  = 0     

II. 21y² - 13y + 2  =0

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

Equation 1: 2x² - 8x + 6 = 0

Equation 2: y² - 7y + 10 = 0

I. 20x² - 93x + 108 = 0

II.72y² - 47y - 144 = 0

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

I. 12y² + 11y – 15 = 0

II. 8x² – 6x – 5 = 0
