Class 3 Maths Olympiad Sample Papers with Step-by-Step Solutions PDF (2026 Edition)

Practicing with realistic, syllabus-authentic sample papers is the single highest-yield activity for Class 3 Olympiad aspirants. However, standard workbook sample papers suffer from two major flaws: 1. Printed Answers at the Back: Young children inevitably peek at the answers after 2 minutes of struggle. 2. Screen-Heavy Online CBT Quizzes: Staring at a laptop screen for 60 minutes causes severe visual fatigue and does not prepare the child for the physical pencil-and-paper OMR exam hall.

OlympiadChamp solves this with the Zero-Screen Hybrid Mock System.

5 Sample Questions from the Diagnostic Paper

Here are 5 representative questions from the test booklet along with detailed explanations from our mascot tutor, Oly:

Q1. Logical Reasoning (Patterns)

Question: Find the next number in the pattern: 14, 28, 42, 56, __?

(A) 68

(B) 70 (Correct)

(C) 72

(D) 60

Mascot Explanation by Oly:

Look at the step difference: $28 - 14 = 14$, $42 - 28 = 14$, $56 - 42 = 14$. This is simply the 14 times table! $56 + 14 = 70$. Option (B) is correct.

Q2. Mathematical Reasoning (Place Value & Face Value)

Question: What is the difference between the place value and the face value of the digit 8 in the numeral 4,829?

(A) 800

(B) 792 (Correct)

(C) 8

(D) 720

Mascot Explanation by Oly:

In 4,829, the digit 8 sits in the Hundreds place, so its Place Value is $8 \times 100 = 800$.

The Face Value of any digit is simply the digit itself, which is $8$.

Difference = $800 - 8 = 792$. Option (B) is correct.

Q3. Mathematical Reasoning (Missing Digit Addition)

Question: In the addition: 3,[]45 + 1,283 = 5,128, which single digit replaces the square []?

(A) 7

(B) 8 (Correct)

(C) 9

(D) 6

Mascot Explanation by Oly:

To find the unknown addend, subtract the known addend from the sum:

$5,128 - 1,283 = 3,845$.

Comparing $3,[?]45$ with $3,845$, the missing digit in the hundreds place is 8. Option (B) is correct.

Q4. Everyday Mathematics (Shopping & Money)

Question: Rohan bought an encyclopedia for Rs. 185 and a geometry compass box for Rs. 65. He gave a Rs. 500 banknote to the cashier. How much change will he receive?

(A) Rs. 240

(B) Rs. 250 (Correct)

(C) Rs. 260

(D) Rs. 270

Mascot Explanation by Oly:

Step 1: Add total expenses = $\text{Rs. } 185 + \text{Rs. } 65 = \text{Rs. } 250$.

Step 2: Subtract from amount given = $\text{Rs. } 500 - \text{Rs. } 250 = \text{Rs. } 250$. Option (B) is correct.

Q5. Achievers Section HOTS (Balance Scale Puzzle)

Question: On a fruit balancing scale: 3 balanced apples weigh the same as 1 pineapple. 2 pineapples balance 1 large watermelon. How many apples balance 1 watermelon?

(A) 5 Apples

(B) 6 Apples (Correct)

(C) 8 Apples

(D) 9 Apples

Mascot Explanation by Oly:

Let's substitute:

1 Watermelon = 2 Pineapples.

Since each Pineapple = 3 Apples, 2 Pineapples = $2 \times 3 = 6$ Apples.

Therefore, 1 Watermelon balances exactly 6 Apples! Option (B) is correct.
