A+B means A is the sister of B. A*B means A is the wife of B. A%B means A is the father of B. A-B means A is the brother of B. T is the daughter of P in which of the following statements.
- A.

- C.
P*Q%R+T-S
- D.
P*Q%R+S+T
Correct Answer
B. P*Q%R-T+SExplanation
In the given statement "P*Q%R-T+S", T is the daughter of P. This can be determined by analyzing the symbols used in the statement. The symbol "-" represents the relationship of being a brother, so "P-Q" means P is the brother of Q. The symbol "%" represents the relationship of being a father, so "P%R" means P is the father of R. Finally, the symbol "*" represents the relationship of being a wife, so "P*Q" means P is the wife of Q. Since T is connected to P through the symbol "-", it implies that T is the daughter of P.Rate this question:

15 years hence, a man will be 4 times as old as he was 15 years ago. What is his age after 5 years?
- A.
25
- B.
30
- C.
35
- D.
15
Correct Answer
B. 30Explanation
In the given question, it is mentioned that 15 years from now, the man will be 4 times as old as he was 15 years ago. Let's assume the man's current age is x. 15 years ago, his age would have been x-15. Therefore, 15 years from now, his age will be x+15. According to the given condition, x+15 = 4(x-15). Solving this equation, we get x = 30. So, the man's current age is 30. After 5 years, his age will be 30+5 = 35. Therefore, the correct answer is 35.Rate this question:

One morning Geetha and Swathi were talking to each other in a park. They were standing face to face. If Geetha's shadow fell exactly to the right of Swathi. Then in which direction was Swathi facing?
- A.
East
- B.
West
- C.
South
- D.
North
Correct Answer
C. SouthExplanation
Since Geetha's shadow fell exactly to the right of Swathi, it means that the sun was shining from the west. In this case, if Geetha's shadow is to the right of Swathi, it implies that Swathi was facing north, as her shadow would fall behind her towards the south. Therefore, the direction Swathi was facing is North.Rate this question:

B and F
- D.
G and C
Correct Answer
A. F and DExplanation
A is next to the right of F, so F is on the left side of A. Since C is third to the left of B and C is at one end, B must be on the right side of A. Therefore, F and B are on both sides of A. D is not mentioned in any of the given statements, so it cannot be on both sides of A. The correct answer is F and B.Rate this question:

Find the angle between hours and minute hands of the clock at 3:30 PM.
- A.
72
- B.
65
- C.
90
- D.
75
Correct Answer
D. 75Explanation
At 3:30 PM, the hour hand is pointing at the 3 on the clock and the minute hand is pointing at the 6 on the clock. The angle between the hour and minute hands can be calculated by finding the difference between their positions. Since the hour hand moves 30 degrees per hour and the minute hand moves 6 degrees per minute, we can calculate the angle by multiplying the number of hours by 30 and the number of minutes by 6, and then finding the difference. In this case, the hour hand has moved 90 degrees (3 hours * 30 degrees per hour) and the minute hand has moved 180 degrees (30 minutes * 6 degrees per minute). The difference between these two positions is 90 degrees, so the answer is 90.Rate this question:

The conclusion "Some tubes are packets" follows from the given statements. Since all buckets are tubes, and some packets are buckets, it is possible for some tubes to be packets. However, there is no information given to support the conclusions "Some tubes are stamps" or "Some buckets are stamps", so neither of those conclusions follows. Therefore, only conclusion 3 follows.Rate this question:

If 20% of the students playing football from school A also play badminton, then what would be the total number of students playing badminton from school A?
- A.
110
- B.
120
- C.
100
- D.
None of these
Correct Answer
C. 100Explanation
If 20% of the students playing football from school A also play badminton, then it means that out of every 100 students playing football, 20 of them also play badminton. Therefore, the total number of students playing badminton from school A would be 20% of the total number of students playing football, which is 20% of 100, equal to 20.Rate this question:

If there is 10% increase in the number of students who play football and 20% decrease in the number of students who play badminton, then the ratio of total number students playing football to those who play badminton is:
- A.
11/8
- B.
66/53
- C.
11/80
- D.
99/32
Correct Answer
D. 99/32Explanation
If there is a 10% increase in the number of students playing football, it means that the number of students playing football has increased by 10% of its original value. Similarly, if there is a 20% decrease in the number of students playing badminton, it means that the number of students playing badminton has decreased by 20% of its original value.
To find the ratio of the total number of students playing football to those playing badminton, we need to compare the updated values.
Let's assume the original number of students playing football is represented by F, and the original number of students playing badminton is represented by B.
After a 10% increase, the new number of students playing football is 1.1F (F + 10% of F).
After a 20% decrease, the new number of students playing badminton is 0.8B (B - 20% of B).
Therefore, the ratio of the total number of students playing football to those playing badminton is (1.1F) / (0.8B), which simplifies to 11/8.Rate this question:
