The phrase "revolves around" indicates that the business model is centered or dependent on trust.

The difference in speed between the two cars is 60 km/h - 50 km/h = 10 km/h. Relative speed between car is 10 km/h. 

Distance between the car will increase due to this relative velocity.  20 km gap  at a speed of 10 km/h, it will take 20 km/ 10 km/h = 2 hours.

Answer: B)  2

Let the original share of each friend be x. So, the total cost of the gift = 10 * x

When 2 friends don't contribute, the remaining 8 friends pay (x + 150) each.

• 8 * (x + 150) = 10 * x

•  x = 600.

• Therefore, the total cost of the gift = 10 * 600 = 6000.

Answer: (C) 6000

Answer: D) a school

A judge is the primary authority in a court, and a teacher is the primary authority in a school. This is an analogy based on the relationship between a place and the person in charge.

Given that only one statement is true, let's analyze the possibilities:

• If P's statement (“Q committed the crime”) is true:

  • Q committed the crime.

  • Then, Q's statement (“S committed the crime”) must be false.

  • So, S did not commit the crime.

  • R's statement (“I didn't do it”) is false. Means R committed the crime

  • Q and R both can not commit the crime hence no conclusion

• If Q's statement (“S committed the crime”) is true:

  • S committed the crime.

    • R's statement (“I didn't do it”) is false. Means R committed the crime

    • S and R both can not commit the crime hence no conclusion

• If R's statement (“I didn't do it”) is true:

  • R did not commit the crime.

  • P statement is false. Means Q did not committed the crime

  • Q statement is false. Means S did not committed the crime

  • S statement is false. Means what Q says. Hence S committed the crime which is contradictory to the above statement

  • Hence no conclusion

• If S's statement (“What Q said about me is false”) is true:

  • P & Q's statements must be false. Hence Q & S did not commit the crime.

  • R statement is false 

  • Hence R committed the crime

Therefore, the criminal who committed the crime, given that only one statement is true, is R. Hence, the correct answer is (B) R.

Total numbers of persons = 70 + 10 + 20 + 20 + 40 = 160

Numbers of administrators = 10 + 20 +20 = 50

% administrators = (50 x 100)/ 160 = 31.25

Answer: C

The passage clearly states that begging is a symptom of the failure of the state to protect citizens who fall through the social security net. This implies that inadequate social welfare systems contribute to the problem of begging.

Answer: B) Beggars are created because of the lack of social welfare schemes.

Let's denote:

• D = Drama club

• M = Maths club

• Da = Dance club

Given:

• Only D = 60

• Only M = 30

• Only Da = 80

• D ∩ Da = 40

• Da ∩ M = 12

• D ∩ M = 7

• D ∩ Da ∩ M = 2

Students Only in D & Da

= (D ∩ Da) - (D ∩ Da ∩ M) = 40-2 = 38

Students Only in Da & M 

= (Da ∩ M) - (D ∩ Da ∩ M) = 12 - 2 = 10

Students Only in D & M

= (D ∩ M) - (D ∩ Da ∩ M) = 7-2 = 5

Total students in clubs 

= Only D + Only M + Only Da + Only D & Da + Only Da & M + Only D & M + students in all clubs

= 60 + 30 + 80 + 38 + 10 + 5 + 2 = 225

75% of the students are not in any club, so 25% are in clubs. 

Total students 225 x 4 = 900

Answer: C) 900
