Queen Airlines offers the following Privilege programme: there are 5 membership tiers, each with its own set of enhanced tier-specific benefits. New members join at the Blue tier, then upgrade to Blue Plus, which adds the benefit of Tele check-in. The programme also has three elite tiers, Silver, Gold and Platinum. The 6-month fast-track upgrade and the 12-month standard upgrade system work in parallel: whenever a passenger meets the condition for the next tier, either in terms of the number of flights taken in the stipulated period or in terms of accumulated Queen-Miles, in either of the two systems, the passenger is automatically upgraded to the next tier. The 6-month system looks at a rolling 6-month period, and the 12-month system looks at a rolling 12-month period. If conditions for more than one upgrade are met at the same time, the passenger is given the higher of the two tiers.

Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Identify the first tier upgrade.
Kakkar's first upgrade is Blue to Blue Plus. As shown in question 78, he reaches 3 flights by 3 February 2007, meeting the 6-month fast-track threshold of 3 flights, so his first upgrade date is 3 February 2007.
Step 2: Identify the last tier upgrade.
Continuing the flight log used in question 79, Kakkar's last upgrade is Gold to Platinum, on his 10th flight as a Gold member, which lands on 4 November 2007.
Step 3: Count the complete calendar months between these two dates.
The first upgrade, 3 February 2007, is a partial month since it starts on the 3rd, and the last upgrade, 4 November 2007, is also a partial month since it falls on the 4th. Discounting these two partial months, the calendar months that lie fully between them are March, April, May, June, July, August, September and October, which is 8 months.
Final Answer:
The difference between Kakkar's first and last tier upgrade, in complete calendar months, is 8.
\[ \boxed{8} \]

- Direction: Ten pirates - Horvi, Rangirk, Felicia, Ana, Noa, Gangra, Yarsolav, Daman, Lima and King took a vote on who should be the leader.
A pirate always votes for themselves though. So, they decided on voting out the one who shouldn’t be a leader for the first five rounds and for the remaining four rounds, the leader would be voted for. A pirate never votes against themselves.
At the end of each of the nine rounds, one person was eliminated and that person couldn’t take part in the voting. In case of a tie in the voting, eliminated people chose one of the tied people to vote out.
At the end of the voting for the first five rounds – “For who shouldn’t be the leader” - the total votes were as shown as in the table below:Pirate Votes Against Horvi 0 Rangirk 0 Felicia 0 Ana 9 Noa 4 Gangra 5 Yarsolav 5 Daman 6 Lima 4 King 7 In each of the five rounds, only two pirates were voted against. The table given below shows the number of rounds in which each of the pirates was voted against.
Pirate Votes Against in (Number of rounds) Horvi 0 Rangirk 0 Felicia 0 Ana 1 Noa 3 Gangra 1 Yarsolav 1 Daman 1 Lima 1 King 2 It is known that King was not voted out. He was the second most voted pirate in two successive rounds.
Who was eliminated in Round 4 if tie is not possible in the first five rounds? 
It is known that there was a tie in one of the rounds. When Yarsolav was eliminated, who was the 2nd most voted?
What was the number of votes secured by the person who was eliminated in round 5?- There are three sections in a question paper, and each section has 10 questions. First section only has multiplechoice questions, and 2 marks will be awarded for each correct answer. For each wrong answer, 0.5 marks will be deducted. Any unattempted question in this section will be treated as a wrong answer. Each question in the second section carries 3 marks, whereas each question in the third section carries 5 marks. For any wrong answer or unattempted question in the second and third sections, no marks will be deducted. A student’s score is the addition of marks obtained in all the three sections. What is the sixth-highest possible score?
- Go through the information given below, and answer the questions that follow.
The table captures the Age and Gender distribution of COVID-19-positive cases in a country. However, a part of the data is missing, represented through unknown categories.
