The correct answer is D
I. 195x² - 46x - 21 = 0
II. 209y² + 7y - 12 = 0
I. x² + 3x – 154 = 0
II. y² + 5y – 126 = 0
Quantity I: A vessel contains a mixture of milk and water in the ratio of 7 : 5. If 9 litre of mixture is sold and replaced by same amount of water the...
I. 2x² + 11 x + 15 = 0
II. 2y² - 19 y + 44 = 0
I. 5x² + 17x + 6 = 0
II. 2y² + 11y + 12 = 0
...I. 2x2- 5x - 33 =0
II. 2y2+ 5y - 25 = 0
I. 3p² + 13p + 14 = 0
II. 8q² + 26q + 21 = 0
I. 6y2- 17y + 12 = 0
II. 15x2- 38x + 24 = 0
I. 5x² -14x + 8 = 0
II. 2y² + 17y + 36 = 0
I. 2x² - 9x + 10 = 0
II. 3y² + 11y + 6 = 0
