41. Statements: No book is a copy. Some copies are pen. All pens are markers.
Conclusions: I. Some markers are copies. II. No book is a pen.
A. Only I follows
B. Only II follows
C. Both I and II follow
D. Neither I nor II follows
Correct Answer: A. Only I follows
Explanation: Since all pens are markers and some copies are pens, some markers must be copies. (I follows) There is no direct negative relation between books and pens, so II doesn't follow.
42. I. x² - 13x + 40 = 0 II. y² - 15y + 56 = 0
A. x > y
B. x < y
C. x ≥ y
D. x ≤ y
Correct Answer: D. x ≤ y
Explanation: I. x² - 13x + 40 = 0 => (x-5)(x-8) = 0 => x = 5, 8 II. y² - 15y + 56 = 0 => (y-7)(y-8) = 0 => y = 7, 8 Comparing: 5 < 7, 5 < 8 8 > 7, 8 = 8 Wait, 8 > 7. So it's No Relation? Let's re-compare: x=5 is less than y=7 and y=8. x=8 is greater than y=7 and equal to y=8. Since x is both greater than and less than y, no relation can be established.
