Question
72, 36, 54, 135, 470.5,
2126.25Â Find the wrong number in the given number series.Solution
ATQ, 72 X 0.5 = 36 36 X 1.5 = 54 54 X 2.5 = 135 135 X 3.5 = 472.5 472.5 X 4.5 = 2126.25 Therefore, 472.5 will come in place of 470.5.
I. 6x² + 37x + 45 = 0
II. 3y² - 11y + 6 = 0
I. 3y² - 20y + 25 = 0
II. 3x² - 8x + 5 = 0
if x satisfies 3x² – 5x – 12 = 0, find the sum of reciprocals of roots.
I. 96x² + 52x - 63 = 0
II. 77y² + 155y + 72 = 0
I. 2x2 - 5x - 33 =0
II. 2y2 + 5y - 25 = 0
Equation 1: x² - 180x + 8100 = 0
Equation 2: y² - 170y + 7225 = 0
Solve the quadratic equations and determine the relation between x and y:
