Question 2
If $ means ×, @ means +, # means -, % means ÷, then find the value of 9 # 19 @ 7
Substitute symbols: 9 - 19 + 7 = -3
Question 3
Which two numbers should be interchanged to make the equation 2 - 6 × 9 = 17 correct?
Question 4
Simplify: 9 + (9 - (3 ÷ 12) + 8)
Apply BODMAS: brackets first, then multiplication/division, then addition/subtraction to get 8.75
Question 5
Simplify: (11 + 4) - (3 × 8) ÷ 10
Apply BODMAS: brackets first, then multiplication/division, then addition/subtraction to get 12.60
Question 6
Given @ means +, # means -, $ means ×, % means ÷, which symbols should be interchanged to make 10 $ 4 # 7 % 10 = 27?
The equation is already correct or no single interchange works
Question 7
If # means ×, $ means -, @ means +, find 10 @ (6 # 9) $ 5
Step 1: (6 × 9) = 54
Step 2: 10 + 54 - 5 = 59
Step 2: 10 + 54 - 5 = 59
Question 8
A value decreases by 47% and then decreases by 28%. What is the net percentage change?
Step 1: decrease by 47% → multiply by 0.53
Step 2: decrease by 28% → multiply by 0.72
Net change = -61.8%
Step 2: decrease by 28% → multiply by 0.72
Net change = -61.8%
Question 9
If @ means +, # means -, $ means ×, % means ÷, then find the value of (13 @ 10) % 15 $ 14
Step 1: (13 + 10) = 23
Step 2: 23 ÷ 15 × 14 = 21.42
Step 2: 23 ÷ 15 × 14 = 21.42
Question 10
A value increases by 22% and then decreases by 30%. What is the net percentage change?
Step 1: increase by 22% → multiply by 1.22
Step 2: decrease by 30% → multiply by 0.7
Net change = -14.6%
Step 2: decrease by 30% → multiply by 0.7
Net change = -14.6%
Question 11
Which two numbers should be interchanged to make the equation 11 × 11 - 10 = 43 correct?
Question 12
If @ means +, $ means -, # means ×, find 5 @ (3 # 5) $ 9
Step 1: (3 × 5) = 15
Step 2: 5 + 15 - 9 = 11
Step 2: 5 + 15 - 9 = 11
Question 13
If @ means +, $ means -, # means ×, find 10 @ (11 # 7) $ 6
Step 1: (11 × 7) = 77
Step 2: 10 + 77 - 6 = 81
Step 2: 10 + 77 - 6 = 81
Question 14
Simplify: 3 + (11 ÷ (11 ÷ 8) - 3)
Apply BODMAS: brackets first, then multiplication/division, then addition/subtraction to get 3
Question 15
What operator should replace '?' to make 16 ? 7 - 8 = 70?
The correct operator is None because 16 None 7 - 8 = 70
Question 16
Simplify: 11 + (14 + 4) × 14 - 11
Apply BODMAS: brackets first, then multiplication/division, then addition/subtraction to get 252
Question 17
Given: P < Q, S > P, Q > R. Which of the following is definitely true?
From P < Q and S > P, we can deduce S > Q
Question 18
Given @ means +, % means ÷, # means -, $ means ×, which symbols should be interchanged to make 15 @ 12 $ 10 % 4 = 50?
The equation is already correct or no single interchange works
Question 19
Given $ means ×, # means -, @ means +, % means ÷, which symbols should be interchanged to make 7 % 6 $ 5 # 13 = 39?
The equation is already correct or no single interchange works
Question 20
Find the missing number in the sequence: 2, 4, ?, 16
The pattern: Each term increases by 2. Therefore, the missing number is 8
