Roses are a subset of flowers, but we don't know which flowers are red. Some red flowers might not be roses.
Cost Price = 10 × 50 = 500. Selling Price = 10 × 60 = 600. Profit = 100. Profit% = (100/500) × 100 = 20%
Work is inversely proportional to number of workers. (5 × 12) = (10 × x), so x = 6 days
Number = 12k + 5. When divided by 4: 12k + 5 = 4(3k) + 4 + 1 = 4(3k+1) + 1. Remainder = 1
Let numbers be 2x, 3x, 5x. Sum = 2x + 3x + 5x = 10x = 100. x = 10. Largest = 5x = 50
Train + Bus = 60% + 30% = 90%. Walk = 10% = 20 km. Total = 20/0.10 = 200 km
The number could be 11, 18, 25, 32, etc. (of form 7k+4). When divided by 11, remainders vary: 11→0, 18→7, 25→3, 32→10. Cannot determine uniquely.
Rate of A = 1/12, Rate of B = 1/18. Combined rate = 1/12 + 1/18 = 5/36. Time = 36/5 = 7.2 hours
Ephemeral (short-lived) is opposite to Permanent (long-lasting). Similarly, Verbose (using many words) is opposite to Concise (using few words). The analogy requires antonyms.
The pattern is n(n+1) where n = 1,2,3,4,5,6... First term: 1×2=2, Second: 2×3=6, Third: 3×4=12, Fourth: 4×5=20, Fifth: 5×6=30, Sixth: 6×7=42.
