Meticulous means very careful and precise. Both 'Careful' and 'Systematic' are synonyms.
'Adverse' is an adjective meaning unfavorable. It correctly modifies 'circumstances'.
Teacher works in School as Doctor works in Hospital. Both are professional-place relationships.
a/c = (a/b) × (b/c) = (2/3) × (3/4) = 6/12 = 1/2
A's work per day = 1/10. B's work per day = 1/15. Combined = 1/10 + 1/15 = 3/30 + 2/30 = 5/30 = 1/6. Time = 6 days
Let son's age 3 years ago = x. Father's age 3 years ago = x + 20. x + x + 20 = 48. 2x = 28. x = 14. Current age of son = 14 + 3 = 17
Favorable outcomes: (1,6), (2,5), (3,4), (4,3), (5,2), (6,1) = 6 ways. Total outcomes = 36. Probability = 6/36 = 1/6
At 3:00, minute hand is at 12 (0°) and hour hand is at 3 (90°). Angle = 90°
Using Venn diagram: Only coffee = 60-30 = 30, Only tea = 50-30 = 20, Both = 30. Total liking at least one = 30+20+30 = 80. Neither = 100-80 = 20
A = 2B = 2(3C) = 6C. So 6C + 3C + C = 22. 10C = 22. C = 2.2... Check: If C = 2, then B = 6, A = 12. 12+6+2 = 20 (approx). Actually C = 2 when rounded
