### Subtracting 40% of a number:from the number, we get the result as 30. The number is:

• A.

28

• B.

52

• C.

50

• D.

70

C. 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.

### 12.5% of 192=50% of?

• A.

48

• B.

24

• C.

6

• D.

None of these

A. 48
Explanation
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.

### 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?

• A.

240,000

• B.

300,000

• C.

168,000

• D.

36,000

D. 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?

• A.

80

• B.

120

• C.

150

• D.

100

D. 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.

### 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

D. 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.
