110

120

100

None of these

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.

3. A, B, C, D, E, F, G are standing facing to east in the following order :

A is next to right of F.
F is fourth to the right of C.
G car is between B and E.
C which is third to the left of B, is at one end.

Which of these are on both sides of A?

F and D

B and G

B and F

G and C

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.

5.

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:

11/8

66/53

11/80

99/32

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.

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.

8. 15 years hence, a man will be 4 times as old as he was 15 years ago. What is his age after 5 years?

25

30

35

15

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.

9. 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.

P*Q%R+S-T

P*Q%R-T+S

P*Q%R+T-S

P*Q%R+S+T

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.

10. 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?

East

West

South

North

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.

75

To determine the angle between the hour and minute hands of the clock at 3:30 PM, we observe the positions of the hands. At this time, the hour hand points to the 3, and the minute hand points to the 6. By applying the formula for clock angles, which involves multiplying the hours by 30 and subtracting half of the minutes multiplied by 11, we obtain an angle of -75 degrees. Taking the absolute value, we get a positive value of 75 degrees. Therefore, at 3:30 PM, the angle between the hour and minute hands is 75 degrees.
