Question 1

Which of the following numbers is divisible by 11?

Accepted Answer

Step 1: Apply divisibility rule for 11: alternating sum of digits (starting from right) must be divisible by 11. Step 2: For 5742: (2 - 4 + 7 - 5) = 0, which is divisible by 11. Step 3: Therefore, 5742 is divisible by 11.

Question 2

Simplify: 48 ÷ 6 + 12 × 2 − 5

Accepted Answer

Step 1: Apply BODMAS — Division and Multiplication first (left to right). 48 ÷ 6 = 8 and 12 × 2 = 24. Step 2: Now we have 8 + 24 − 5. Step 3: Addition and Subtraction (left to right): 8 + 24 = 32, then 32 − 5 = 27.

Question 3

Evaluate: 100 − 20 × 3 + 15 ÷ 3

Accepted Answer

Step 1: Apply BODMAS — Multiplication and Division first (left to right). 20 × 3 = 60 and 15 ÷ 3 = 5. Step 2: Now we have 100 − 60 + 5. Step 3: Subtraction and Addition (left to right): 100 − 60 = 40, then 40 + 5 = 45.

Question 4

Simplify: 5 + 8 ÷ 4 × 2 − 3

Accepted Answer

Step 1: Apply BODMAS — Division and Multiplication first (left to right). 8 ÷ 4 = 2, then 2 × 2 = 4. Step 2: Now we have 5 + 4 − 3. Step 3: Addition and Subtraction (left to right): 5 + 4 = 9, then 9 − 3 = 6.

Question 5

Calculate: 36 ÷ 9 × 5 + 10 − 8

Accepted Answer

Step 1: Apply BODMAS — Division and Multiplication first (left to right). 36 ÷ 9 = 4, then 4 × 5 = 20. Step 2: Now we have 20 + 10 − 8. Step 3: Addition and Subtraction (left to right): 20 + 10 = 30, then 30 − 8 = 22.
