Ashwin lives immediately above Jay. Ashwin lives above Nilamber. Palak lives on an odd-numbered floor. Only one person lives between Ashwin and Nilamber. Harsh lives on the floor numbered five. Khushi lives above Harsh. On which floor does Ashwin lives?Solution
The correct answer is D
Solve the quadratic equations and determine the relation between x and y:
Equation 1: x² - 38x + 352 = 0
Equation 2: y² - 38y + 312 = 0
Equation 1: 2x2 - 21x + 54 = 0
Equation 2: 4y2 - 23y + 15 = 0
Difference between the roots of equation 1 is approx...
I. 8y2 - 2y - 21 = 0
II. 2x2 + x - 6 = 0
Solve the quadratic equations and determine the relation between x and y:
Equation 1: x² - 36x + 288 = 0
Equation 2: y² - 36y + 320 = 0
I. 40 x² - 93 x + 54 = 0
II. 30 y² - 61 y + 30 = 0
I. x2 - x - 56 = 0
II. y2 - 20y + 96 = 0
If α, β are the roots of the equation x² – px + q = 0, then the value of α2+β2+2αβ is
...I. 2x2 + 3x - 9 = 0
II. 3y2 - y - 10 = 0
I. y² - 7 y – 18 = 0
II. x² + 10 x + 16 = 0
I. x2 - 5x - 14 = 0
II. y2 - 16y + 64 = 0
