Question 4 Explanation:

Given that only one person committed the crime and only one given statement is correct.

**When P is correct and Q, R, S are false:**it implies,Q committed crime, S did not commit crime, R committed crime, S committed crime.

This situation is impossible.**When Q is correct and P, R, S are false:**it implies,Q did not commit crime, S committed crime, R committed crime, S committed crime.

This situation is impossible.**When R is correct and P, Q, S are false:**it implies,Q did not commit crime, S did not commit crime, R did not commit crime, S committed crime.

Question 5 Explanation:

Given two cars at the same time from the same location and go in the same direction with speed of 50 km/h and 60 km/h.
Therefore, after 1 hour,

distance traveled by first car (with speed of 50 km/h) = 50*1 = 50 km And, distance traveled by second car (with speed of 60 km/h) = 60*1 = 60 km So, distance between these cars = 60 - 50 = 10 kmAfter 2 hour,

distance traveled by first car (with speed of 50 km/h) = 50*2 = 100 km And, distance traveled by second car (with speed of 60 km/h) = 60*2 = 120 km So, distance between these cars = 120 - 100 = 20 km

**Alternative way:**→ (distance traveled by second car) - (distance traveled by first car) = 20 km → (STherefore, option (B) is correct._{2}*T) - (S_{1}*T) = 20 → (60*T) - (50*T) = 20 → 10*T = 20 → T = 2

Question 6 |

Ten friends planned to share equally the cost of buying a gifts for their teacher. When two of them decided not to contribute, each of the other friends had to pay Rs. 150 more. The cost of the gift was Rs. _________ .

3000 | |

6000 | |

12000 |

**GATE CS 2019**

**Discuss it**

Question 6 Explanation:

Let share of each student = x
Since cost of gift will be same in both situation, therefore,

→ 10*x = 8*(x + 150) → 10*x = 8*x + 8*150 → 2*x = 8*150 → x = 8*150 / 2 → x = 600Therefore, cost of gift is,

10*x = 10*600 = 6000Option (C) is correct.

Question 8 Explanation:

No of administrator,

= 10+20+20 = 50Total no of person,

Note that given 2 students are in all clubs so these are common in given each two group. After deducting 2, the Venn diagram is,
Therefore, total number of students participating in any of these clubs,

= 60 + 80 + 30 + 38 + 2 + 10 + 5 = 225Given only these are only 25% of the total number of students in the college (75% of the students in the college are not in any of these clubs.). Therefore, total total number of students in the college,

x*0.25 = 225 = 225/0.25 = 900So, option (C) is correct.
