    • E booked an even-numbered floor.

    • A booked the floor, which is immediately before E, who has booked the floor for slot 4.

    • So, there are two cases possible i.e., Case 1 and Case 2.

    • D booked the floor immediately after C and has not booked the floor for Slot 2 and Slot 3.

    • So, Case 2(b) will be invalid.

    • B booked the floor for time Slot S2.

    • The total Bill of D is less than the total bill of A.

    • So, Case 2(a) will be invalid.

    3 / -1

    Directions For Questions

    Directions : Some astronauts decide to launch five ballistic missiles on the same day but at different slots of time. To launch each missile there are three phases i.e., Boost phase, Midcourse and Terminal phase respectively. In each phase the missile takes different times, in the boost phase it takes 15 minutes, in the midcourse it takes 45 minutes and in the terminal phase, it takes 10 minutes. Before entering the midcourse phase after completing the boost phase the missile takes 10 minutes to get ready and before entering the terminal phase after completing the midcourse phase the missile takes 5 minutes to get ready.

    NOTE:

    (a) Missile 1 starts the boost phase at 9:00 am.

    (b) Missile 2 starts the midcourse phase at 3:55 pm.

    (c) Missile 3 starts the terminal phase at 11:50 am.

  • Question 8
    3 / -1

    Directions For Questions

    Directions : Some astronauts decide to launch five ballistic missiles on the same day but at different slots of time. To launch each missile there are three phases i.e., Boost phase, Midcourse and Terminal phase respectively. In each phase the missile takes different times, in the boost phase it takes 15 minutes, in the midcourse it takes 45 minutes and in the terminal phase, it takes 10 minutes. Before entering the midcourse phase after completing the boost phase the missile takes 10 minutes to get ready and before entering the terminal phase after completing the midcourse phase the missile takes 5 minutes to get ready.

    NOTE:

    (a) Missile 1 starts the boost phase at 9:00 am.

    (b) Missile 2 starts the midcourse phase at 3:55 pm.

    (c) Missile 3 starts the terminal phase at 11:50 am.

  • Question 9
    3 / -1

    Directions For Questions

    Directions : Geeta, Meena and Teena participate in a competition for 3 days. Every day, each participant picks up a ball numbered between 1 and 9. The number on the ball determines the score on that day. No two balls picked will have the same number on them. The total score of a participant is the sum of his scores attained in the three days. The one whose total score will be maximum will win the game. The total score of a day is the sum of participant scores on that day. The average score (up to 2 decimals) on three different days is given in Table 1.

    Table 1- Average score of the participants each day.

    Day 1 Day 2 Day 3
    5.67 4 5.34

    The participants are given a rank each day. The person with the maximum score is given a rank as '1' on that day whereas the person with the minimum score is given a rank as '3' on that day. Table 2 shows the rank of the person each day.

    Addition information:

    (a) On day 1, everyone scores the odd-numbered score.

    (b) On day 2, everyone scores the even-numbered score.

    (c) Teena scores one score less than day 1 on day 3.

    (d) Geeta scores the odd-numbered score on day 3 which is also the multiple of 5.

    On which of the following days does Teena score the maximum?

    Solution

    Table 1- Average score of the participants each day.

    Day 1 Day 2 Day 3
    5.67 4 5.34

    So, the total score of the participants each day

    Day 1: 5.67 x 3 = 17.01 = 17

    Day 2: 4 x 3 = 12

    Day 3: 5.34 x 3 = 16.02 = 16
