1. If 3𝑥 + 7 = 22, what is the value of 𝑥?
A) 3
B) 4
C) 5
D) 6
Solve for x: 3x + 7 = 22 → 3x = 15 → x = 5.
2. A certain company’s profit increased from $200,000 to $250,000 in one
year. What was the percent increase?
A) 20%
B) 25%
C) 30%
D) 35%
Percent increase = ((250,000 – 200,000)/200,000) × 100 = 25%.
3. If 𝑥is an integer and 2𝑥 + 3 < 11, what is the greatest possible value of 𝑥?
A) 3
B) 4
C) 5
D) 6
2x + 3 < 11 → 2x < 8 → x < 4 → largest integer x = 3.
Correction: carefully read — greatest integer satisfying inequality is 3.
Correct answer is A) 3.
, 4. The average of five numbers is 12. If one of the numbers is 20, what is the
average of the remaining four numbers?
A) 11
B) 12
C) 13
D) 10
Total sum = 12 × 5 = 60; sum of remaining 4 = 60 – 20 = 40; average = 40 ÷ 4
= 10.
5. If 𝑥 2 − 9 = 0, what are the possible values of 𝑥?
A) 3 only
B) -3 only
C) 3 and -3
D) 0
Factor: x² – 9 = (x – 3)(x + 3) = 0 → x = 3, –3.
6. A train travels 120 miles in 2 hours. At the same speed, how long will it take
to travel 300 miles?
A) 4 hours
B) 5 hours
C) 6 hours
D) 7 hours
Speed = 120 ÷ 2 = 60 mph → time = 300 ÷ 60 = 5 hours.
7. If 𝑥is an integer, is 𝑥 2 divisible by 4?
(1) 𝑥is even
(2) 𝑥is divisible by 2
A) Statement 1 alone is sufficient
B) Statement 2 alone is sufficient
C) Both statements together are sufficient
D) Each alone is sufficient
E) Neither is sufficient
Both statements mean x is even → x² divisible by 4. Actually, Statement 1 or
Statement 2 alone implies x is even → sufficient. Correct answer: D).
