Here are a few questions from this part. Take the full test to answer all 20 and get your score.
Sample question 1
(2×1÷2), (4÷1×2), (6×1÷2), _____
- 8
- 16
- 4
- 32
Answer: 16
(2×1÷2), (4÷1×2), (6×1÷2), (8×1÷2)
Since (8÷1×2) is not found in the choices,
so we have to solve this. (8÷1×2) = 16
Since (8÷1×2) is not found in the choices,
so we have to solve this. (8÷1×2) = 16
Sample question 2
(15-8+3), 8, (4÷2×3), ____
- 4
- 3
- 8
- 2
Answer: 4
(15-8+3), 8, (4÷2×3),___
10, 8, 6, 4
10, 8, 6, 4
Sample question 3
Simplify:
33 1/3 % of 48 + 12 1⁄2 % of 96 – 44 4/9 % of 27
- 12
- 16
- 24
- 48
Answer: 16
33 1/3% of 48 = 48 ÷ 3 = 16
12 1/2% of 96 = 96 ÷ 8 = 12
44 4/9% = 4/9, so 4/9 of 27 = 12
16 + 12 − 12 = 16
12 1/2% of 96 = 96 ÷ 8 = 12
44 4/9% = 4/9, so 4/9 of 27 = 12
16 + 12 − 12 = 16
Sample question 4
12 is 125% of what number?
- 9.6
- 8
- 9
- 10
Answer: 9.6
12 = 1.25 × N
12/1.25 = N = 9.6
12/1.25 = N = 9.6
Sample question 5
What percent of 16 is 40?
- 2.5%
- 2500%
- 1/4
- 250%
Answer: 250%
N × 16 = 40
N = 40/16 = 2.5×100% = 250%
N = 40/16 = 2.5×100% = 250%
