Concept Booster: General Intelligence Questions with Explanations

Understanding concepts behind general intelligence questions is very important for SSC and other competitive exams. This section explains the logic behind important general intelligence questions, reasoning MCQ, and analytical reasoning problems. By learning these explanations, you can improve your reasoning ability, accuracy, and problem-solving speed.

1. Number Series: 2, 6, 12, 20, ?

👉 Pattern:
2 → 6 (+4)
6 → 12 (+6)
12 → 20 (+8)

✔ Increasing by +2 each time
Next: +10

👉 Answer = 30

2. Coding-Decoding: CAT = 24, DOG = ?

👉 CAT → C(3) + A(1) + T(20) = 24

DOG → D(4) + O(15) + G(7)

👉 Answer = 26

3. Mirror Image of TRAIN

👉 Mirror reverses order

TRAIN → NIART

👉 Answer = NIART

🔹 4. Odd One Out

👉 Identify category mismatch
Example logic:

• Apple, Banana, Mango → Fruits
• Car → Not a fruit

👉 Answer = Car (different category)

🔹 5. Series: 3, 6, 12, 24, ?

👉 Pattern: ×2
3 → 6 → 12 → 24

👉 Answer = 48

🔹 6. Series: 1, 4, 9, 16, ?

👉 Pattern: Squares
1², 2², 3², 4²

👉 Next = 5² = 25

🔹 7. Clock Problem: 6:00

👉 Formula:
Angle = |30H – 5.5M|

At 6:00 → H=6, M=0

Angle = 30×6 = 180°

👉 Answer = 180°

🔹 8. Coding: MANGO = NBOHP

👉 Each letter +1
M→N, A→B, N→O, G→H, O→P

APPLE → BQQMF

👉 Answer = BQQMF

🔹 9. Series: 2, 5, 10, 17, ?

👉 Pattern:
+3, +5, +7

Next: +9

👉 Answer = 26

🔹 10. Divisible by 9 Rule

👉 Sum of digits divisible by 9

Example:
729 → 7+2+9 = 18 ✔ divisible

👉 Answer = Any number whose digit sum is divisible by 9

🔹 11. Arrange Order

👉 Logical order:
Paragraph → Page → Chapter → Book

👉 Answer = Paragraph → Page → Chapter → Book

🔹 12. A=1, B=2 … Z=?

👉 Alphabet position

Z = 26

🔹 13. Letter Series: A, C, F, J, ?

👉 Pattern:
+2, +3, +4

Next: +5

J + 5 = O

👉 Answer = O

🔹 14. Blood Relation

A = brother of B
B = sister of C

👉 A is also sibling of C

👉 Answer = Brother

🔹 15. Series: 4, 9, 16, 25, ?

👉 Pattern: Squares
2², 3², 4², 5²

👉 Next = 6² = 36

Final Revision Tips

✔ Practice number series daily
✔ Learn coding-decoding patterns
✔ Memorize square numbers (1–30)
✔ Understand basic alphabet positions
✔ Practice clock and blood relation problems regularly
