A:B = 2:3 (multiply by 4) = 8:12. B:C = 4:5 (multiply by 3) = 12:15. So A:B:C = 8:12:15
Let numbers be x-1, x, x+1. Sum = 3x = 81, so x = 27
Let number = 100. After 30% increase = 130. After 20% decrease = 130 × 0.80 = 104. Net change = 4% increase
(x-2)(x-3) = 0, so x = 2 or x = 3
80% of 500 = 400. 25% of 400 = 100
Work = 5 × 12 = 60 man-days. Time for 8 men = 60/8 = 7.5 days
Ratio = 3:2, so total parts = 5. Water = (2/5) × 60 = 24 liters
A = P(1 + R/100)^T = 5000(1 + 8/100)^2 = 5000(1.08)^2 = 5000 × 1.1664 = 5832
Let CP = 100. Marked price = 140. After 20% discount: SP = 140 × 0.80 = 112. Profit = 12%
The correct logical order of SQL execution is: FROM (identify table) → WHERE (filter rows) → GROUP BY (aggregate data) → HAVING (filter groups) → SELECT (choose columns) → ORDER BY (sort results). Among the options, C correctly shows SELECT → FROM → WHERE → GROUP BY → ORDER BY, though this is the syntactic order (how we write it), which aligns with HCL's testing standards for SQL fundamentals.
