AFCT Mathematical Aptitude 1 — Questions and Answers
Question 1: What is the value of 8 + 3 × 5?
- 43
- 31
- 23 (Correct answer)
- 51
Correct answer: 23
To solve 8 + 3 × 5, the order of operations (PEMDAS/BODMAS) must be followed, which dictates that multiplication takes precedence over addition. First, calculate 3 × 5, which equals 15. Then, add 8 to 15, resulting in a final value of 23.
Question 2: If a rectangle has a length of 12 meters and a width of 7 meters, what is its area?
- 19
- 48
- 84 (Correct answer)
- 28
Correct answer: 84
The area of a rectangle is calculated by multiplying its length by its width. For a rectangle with a length of 12 meters and a width of 7 meters, the area is found by multiplying 12 × 7. This calculation yields an area of 84 square meters.
Question 3: Solve for x: 4x - 7 = 9
- x = 4 (Correct answer)
- x = 5
- x = 2
- x = 3
Correct answer: x = 4
To solve the equation 4x - 7 = 9 for x, first add 7 to both sides of the equation to isolate the term with x, which gives 4x = 16. Next, divide both sides by 4 to find the value of x. This results in x = 4.
Question 4: What is the value of 5² - 6 × 3 + 2?
- 9 (Correct answer)
- 16
- 13
- 11
Correct answer: 9
To solve 5² - 6 × 3 + 2, follow the order of operations (PEMDAS/BODMAS). First, calculate the exponent: 5² = 25. Next, perform the multiplication: 6 × 3 = 18. The expression becomes 25 - 18 + 2. Finally, perform subtraction and addition from left to right: 25 - 18 = 7, and 7 + 2 = 9.
Question 5: A car travels 180 miles in 3 hours. What is the average speed of the car?
- 50 mph
- 60 mph (Correct answer)
- 70 mph
- 75 mph
Correct answer: 60 mph
Average speed is calculated by dividing the total distance traveled by the total time taken. In this scenario, the car travels 180 miles in 3 hours. Dividing 180 miles by 3 hours gives an average speed of 60 miles per hour (mph).
