🔢 Section 1 — Patterns & Sequences
Find the Missing Number!
Look at the pattern carefully. Each sequence follows a rule — find it and you'll find the answer!
Question 1 of 10
What number comes next in this sequence?
2 → 4 → 8 → 16 → ?
Question 2 of 10
Find the missing letter in this pattern:
A C E G ?
Question 3 of 10
What is the next number in this Fibonacci-style sequence?
1 1 2 3 5 8 ?
🔐 Section 2 — Coding & Decoding
Crack the Secret Code!
Each word is coded using a hidden rule. Find the rule — then apply it to the question!
Question 4 of 10
If CAT = 3120 and DOG = 4157, what does BAT equal?
C=3 A=1 T=20 | D=4 O=15 G=7
Question 5 of 10
In a secret code, MANGO is written as NBOHP. Using the same code, how is APPLE written?
M→N A→B N→O G→H O→P
⚙️ Section 3 — Algorithm Tracing
Follow the Robot's Instructions!
Read the steps carefully and trace what happens. Act like a "dumb robot" — follow EXACTLY what is written!
Question 6 of 10
A robot follows these steps. What does it print at the end?
Step 1: x = 5
Step 2: x = x + 3
Step 3: x = x × 2
Step 4: Print x
Step 2: x = x + 3
Step 3: x = x × 2
Step 4: Print x
Question 7 of 10
How many times will "Hello" be printed?
count = 1
REPEAT while count ≤ 4:
Print "Hello"
count = count + 1
REPEAT while count ≤ 4:
Print "Hello"
count = count + 1
🧠 Section 4 — Logical Reasoning
Think Carefully — Don't Be Tricked!
These questions test how well you reason logically. Read every word carefully before answering!
Question 8 of 10
All birds can fly. A penguin is a bird. What can we say about penguins based on ONLY these two statements?
Question 9 of 10
Rohan is taller than Priya. Priya is taller than Sam. Who is the SHORTEST?
Question 10 of 10 🏁
An AI sorts numbers using Bubble Sort. After ONE pass (left to right), what does the list look like?
Original: 5 3 8 1 4

💡 Pro-Tips for CT & Logic Questions
TRICK 1
The Reverse Hack: In Coding-Decoding, check the LAST letter of the options first — it's usually the only one that's different and gives away the answer fastest!
TRICK 2
Dry Run Method: For algorithm tracing, take a pencil and write each variable's value after every step. Never do it in your head — always write it down!
TRICK 3
The Pattern Rule: For number sequences, check in order: is it +something? Then ×something? Then Fibonacci? These 3 rules cover 90% of all pattern questions!
TRICK 4
Logic Trap Alert: When a reasoning question seems "too obvious," it's probably a trick. Re-read the EXACT words — especially "all," "some," "only," "never."
