Explanation
All roses are flowers , meaning every rose is included in the category of flowers. Some flowers are red , which means at least a few flowers in the broader category are red.

Since roses are part of the flower category, it logically follows that some roses must be red .

Explanation
Assigning numerical values based on a pattern: B = 5, E = 6, A = 4, T = 2 → BEAT = 5642 S = 6, W = 6, E = 9, E = 1, T = 2 → SWEET = 66912 T = 9, E = 6, A = 1, S = 6, E = 2 → TEASE = 96162 .

Explanation
Step 1: Determine the price per kilogram Given the price of 1.5 kg apples is Rs. 60, let's find the price per kilogram. Price per kg = Total price / Total weight in kg = 60 / 1.5 Step 2: Calculate the price per kilogram Price per kg = 60 / 1.5 = 40 Rs/kg Step 3: Calculate the price for 200 grams First, convert 200 grams to kilograms: 200 grams = 0.2 kg Price for 200 grams = Price per kg * Weight in kg = 40 * 0.2 Step 4: Calculate the price Price for 200 grams = 40 * 0.2 = 8 Rs

Explanation
Step 1: Determine the pattern Given 3 = 6, 6 = 30, and 5 = 20, let's find the pattern. For 3 = 6, it could be 3 * 2 = 6. For 6 = 30, it could be 6 * 5 = 30. For 5 = 20, it could be 5 * 4 = 20. Step 2: Identify the pattern The pattern seems to be n * (n-1) or another pattern based on the given numbers. Step 3: Test the pattern n * (n-1) or n * x If we apply n * (n-1): 3 * (3-1) = 3 * 2 = 6 6 * (6-1) = 6 * 5 = 30 5 * (5-1) = 5 * 4 = 20 This pattern fits. Step 4: Apply the pattern to 7 7 * (7-1) = 7 * 6 = 42

Explanation
Given the sequences: CAT = 1, 2, 3 INK = 4, 5, 6 DOG = 7, 8, 9 ACTION = 10, 11, 12, 13, 14, 15

Explanation
Car A: 6 km right, then 2 km left = 4 km right of the start Car B: 6 km left, then 2 km right = 4 km left of the start Distance between them = 4 km + 4 km = 8 km

Explanation
Step 1: Identify the pattern Let's analyze the given numbers: 101 = 20: 10 * 2 = 20 (first two digits multiplied) 354 = 75: 3 * 25 = 75 (first digit * last two digits) 333 = 63: 3 * 21 = 63 (first digit * last two digits) Step 2: Apply the pattern If the pattern is the first digit multiplied by the last two digits: 828: 8 * 20.25 doesn't fit directly, but 8 * 20 = 160 + 2 = 162 (8 * 20 + 2 = 162), or simply 8 * (20 + 0.25) = 162. However, a simpler pattern could be: 101: 10 * 2 = 20 354: 3 * 25 = 753 33: 3 * 21 = 638 28: 8 * 20.25 = 162
