Question
Statements: Mostly table is chair. Only
chair is desk. No table is board. Conclusions: I. No desk is board. II. All chair can be board. In the question below there are three statements followed by two conclusions I and II. You have to take the three given statements to be true even if they seem to be at variance from commonly known facts and then decide which of the given conclusions logically follows from the three statements disregarding commonly known facts.Solution
Only chair is desk → All desk are chair and desk cannot have negative relation with anyone. Hence conclusion I follows but conclusion II does not follow.
I. 8y2 - 2y - 21 = 0
II. 2x2 + x - 6 = 0
I. 4x² -  15x + 9 = 0
II. 20y² -  23y + 6 = 0
I. 40x² + 81x + 35 = 0
II. 63y² + 103y + 42 = 0
Solve the quadratic equations and determine the relation between x and y:
Equation 1: x² - 20x + 96 = 0
Equation 2: y² - 18y + 72 = 0
I:Â x2Â - 33x + 242 = 0
II:Â y2Â - 4y - 77 = 0
I. x2 – 13x + 40 = 0
II. 2y2 – 15y + 13 = 0Â
I. 5x² = 19x – 12
II. 5y² + 11y = 12
I. 81x - 117√x + 40 = 0
II. 81y - 225√y + 136 = 0
I. x² - 19x + 84 = 0
II. y² - 25y + 156 = 0
Solve the quadratic equations and determine the relation between x and y:
Equation 1: x² - 24x + 135 = 0
Equation 2: y² - 26y + 153 = 0
