Q661.If 3x + 15 = 45, what is the value of x?
Correct Answer: B
3x = 45 - 15 => 3x = 30 => x = 10 (FPSC 2025).
Q662.What is the average of 10, 15, 20, 25, and 30?
Correct Answer: B
Sum = 100. Average = 100 / 5 = 20 (FPSC 2025).
Q663.Solve for y: 4y - 8 = 2y + 12.
Correct Answer: C
4y - 2y = 12 + 8 => 2y = 20 => y = 10 (FPSC 2025).
Q664.The ratio of two numbers is 3 : 4. If their sum is 140, find the larger number.
Correct Answer: B
3x + 4x = 140 => 7x = 140 => x = 20. Larger is 4*20 = 80 (FPSC 2025).
Q665.A train travels 300 km in 5 hours. What is its speed in km/h?
Correct Answer: B
Speed = Distance / Time = 300 / 5 = 60 km/h (FPSC 2025).
Q666.A factory produces 400 toys per day. If production increases by 15%, how many toys are produced now?
Correct Answer: C
Increase = 400 * 0.15 = 60. New total = 460 (FPSC 2025).
Q667.Find the value of (5^3 - 25) / 10.
Correct Answer: B
(125 - 25) / 10 = 100 / 10 = 10 (FPSC 2025).
Q668.What is the probability of rolling an even number on a standard 6-sided die?
Correct Answer: A
Even numbers are 2, 4, 6 (3 outcomes out of 6) => 3/6 = 1/2 (FPSC 2025).
Q669.If a rectangle has length 12 cm and width 8 cm, what is its area?
Correct Answer: C
Area = Length * Width = 12 * 8 = 96 cm² (FPSC 2025).
Q670.A dynamic sum is split in the ratio of 2:5:6. If the smallest share is 18, find the total sum.
Correct Answer: C
2x = 18 => x = 9. Total ratio parts = 13. Total sum = 13 * 9 = 117 (FPSC 2025).
Q671.What is the perimeter of a square with an area of 64 cm²?
Correct Answer: B
Side = sqrt(64) = 8 cm. Perimeter = 4 * 8 = 32 cm (FPSC 2025).
Q672.If the cost price of a product is Rs. 500 and the selling price is Rs. 650, what is the profit percentage?
Correct Answer: C
