Subtracting 40% of a number:from the number, we get the result as 30. The number is:
- 28
- 52
- 50
- 70
Correct Answer

A. 50

Explanation

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.

If A = x% of y and B = y% of x, then which of the following is true?
- A is smaller than B
- A is greater than B
- Cannot be determined
- None of these
Correct Answer

A. None of these

Explanation

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.

In an election contested by two parties, Party D secured 12% of the total votes more than Party R. If party R got 132,000 votes, by how many votes did it lose the election?
- 240,000
- 300,000
- 168,000
- 36,000
Correct Answer

A. 36,000

Explanation

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.

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?
- 80
- 120
- 150
- 100
Correct Answer

A. 100

Explanation

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.
