Test: Multiplication - 1 - Class 3 MCQ

• The relationship is 3 x 6 = 6 x 3 as their answer is the same as 18.
• Therefore, 7 x 4 = 4 x 7 as their answer is the same as 28.

Solution:

• Each flower has 5 petals.
• There are 6 flowers in total.
• To find the total number of petals, multiply the number of petals per flower by the number of flowers:
• 5 petals per flower × 6 flowers = 30 petals in total.

The option is incorrect because:

• 2 x 13 equals 26, not 36.

Solution:

• Each box contains 8 chocolates.
• There are 3 boxes.
• Multiply the number of chocolates per box by the number of boxes: 3 x 8 = 24.

Thus, there are 24 chocolates in total.

• 27 x 10 = 270
• ∴ 160 = 16 x 10
• Therefore, the answer is option (b)

To find the total number of books in the bookcase:

• There are 5 shelves in the bookcase.
• Each shelf can hold 7 books.
• To calculate the total, multiply the number of shelves by the number of books per shelf:

Total books = 5 shelves x 7 books/shelf = 35 books.

The proportion is set up as follows: 45 / ? = 35 / (5 × 7). First, calculate the denominator on the right side:

• 5 × 7 = 35.

So, the equation becomes:

• 45 / ? = 35 / 35.
• 45 / ? = 1.

Solving for ?, we get:

• ?
₌ 45.

Expressing 45 as a product involving 5:

• 45 = 5 × 9.

Thus, the missing number is 5 × 9.

A. 17 x 5 = 85 which is correct
B. 3 x 21 = 63 which is correct
C. 9 x 24 = 216 which is correct
D. 18 x 6 = 104 which is incorrect

Therefore, the answer is option (d).

The task is to identify the odd one out among the given statements. Here's the refined solution:

• In options A, B, and C, the multiplication results are consistent with their stated outcomes.
• Option A: 9×13 appears as repeated 13s.
• Option B: 15×6 equals 90, which is correct.
• Option C: 23×2 is represented by repeated 23s.
• Option D: The multiplication 7×14 equals 98, but it shows repeated 7s instead.

Therefore, the odd one out is option D, as it incorrectly represents the multiplication result.

Solution:
The correct multiplication for 7 × 8 is 56, not 48.
Thus, option (C) is incorrect and the odd one out.
