✔️ Answers & Explanation

Q1. Pattern: n³ + n² → Next = 6³ + 6² = 216+36 = 252

Q2. (1/A + 1/24 = 1/8) → 1/A = 1/8 − 1/24 = 2/24 = 1/12 → 12 days

Q3. Pattern: ×3 −1 → Next = 122×3 −1 = 365

Q4. P(1.1)³ = 1331 → P = 1000

Q5. Ratio = 12 : (20−12) = 12:8 = 3:2

Q6. A:B = 3:5, B:C = 2:7 → A:C = 6:35
(Common B = 10 → A=6, C=35) → 6:35

Q7. Differences: +14, +25, +36, +47 → Next +58 → 187

Q8. SP = 120% of CP → Profit = 20%

Q9. Pattern: n³ + n² → Next = 6³ + 6² = 252

Q10. (1/12 + 1/18) = 5/36 → Time = 36/5 = 7.2 days
