- A.
28
- B.

- C.
50
- D.
70
Correct Answer
C. 50Explanation
If we subtract 40% of a number from the number itself and the result is 30, it means that 60% of the number is equal to 30. To find the original number, we can set up the equation 0.6x = 30, where x represents the number. By dividing both sides of the equation by 0.6, we find that x = 50. Therefore, the number is 50.Rate this question:

- D.
None of these
Correct Answer
A. 48Explanation
To find 50% of a number, we can multiply the number by 0.5. In this case, we need to find a number that is 12.5% of 192. To do this, we can divide 192 by 0.125 (12.5% expressed as a decimal), which equals 1536. Now, we need to find 50% of this number. Multiplying 1536 by 0.5 gives us 768. Therefore, the correct answer is 768 and not given in the options.Rate this question:

- D.
36,000
Correct Answer
D. 36,000Explanation
Party R got 132,000 votes. Party D secured 12% more votes than Party R. To find the number of votes Party D secured, we calculate 12% of 132,000, which is 15,840. Therefore, Party D secured 132,000 + 15,840 = 147,840 votes. To find the number of votes Party R lost the election by, we subtract Party R's votes from Party D's votes: 147,840 - 132,000 = 15,840. Therefore, Party R lost the election by 15,840 votes.Rate this question:

In a certain school, 20% of students are below 8 years of age. The number of students above 8 years of age is equal to the number of students of 8 years of age which is 48. What is the total number of students in the school?
- A.
80
- B.
120
- C.
150
- D.
100
Correct Answer
D. 100Explanation
Let the total number of students in the school be x. Since 20% of students are below 8 years of age, the number of students below 8 years of age is 0.2x. The number of students above 8 years of age is equal to the number of students of 8 years of age, which is 48. So, 0.2x + 48 + 48 = x. Solving this equation, we get x = 100. Therefore, the total number of students in the school is 100.Rate this question:

If A = x% of y and B = y% of x, then which of the following is true?
- A.
A is smaller than B
- B.
A is greater than B
- C.
Cannot be determined
- D.
None of these
Correct Answer
D. None of theseExplanation
The statement "None of these" is the correct answer because A and B are equal. This can be proven by substituting values for x and y. For example, let's say x = 10 and y = 20. In this case, A would be 10% of 20 which is 2, and B would be 20% of 10 which is also 2. Therefore, A is not smaller or greater than B, and it can be determined that the answer is none of these options.Rate this question:
