    Statement I is not sufficient as the size of the ice cube and height of the container is not known hence statement I is not sufficient alone.
    Statement I is not sufficient as the dimension of the container is not known.
    We cannot answer the question even by combining both the statement as the height of the container is not known.

    Correct Option: D

    Using Statement I: If the time is 9 o'clock now then after 30 minutes ie at 9:30 the angle between the minute and hour hand cannot be 90°. So, now time is not 9 o'clock.
    Using Statement II: If the time is 9 o'clock now then after 15 minutes before the hour and minute hand of the clock can never coincide with each other Instead they will have an angle of 7.5°. So, the time now is not 90°' clock.

    Correct Option: C

    Using Statement I: If the time is 9 o'clock now then after 30 minutes ie at 9:30 the angle between the minute and hour hand cannot be 90°. So, now time is not 9 o'clock.
    Using Statement II: If the time is 9 o'clock now then after 15 minutes before the hour and minute hand of the clock can never coincide with each other Instead they will have an angle of 7.5°. So, the time now is not 90°' clock.

    I. A sites to the left of B. B faces the centre. D and E are immediate neighbours of each other. C sits second to the right of E.
    II. D sits second to right of C. C faces the centre. Both E and A are immediate neighbours of D. B sits second to the right of A.

    Using Statement I: We cannot determine if all the fiends are facing the centre.
    A is the facing outside of C is facing the centre of circle. So, all friends are not facing the centre.

    Correct Option: B

    Using Statement I: We cannot determine if all the fiends are facing the centre.
    A is the facing outside of C is facing the centre of circle. So, all friends are not facing the centre.

    Using Statement I:
    Q > R > S > T > P,
    Q is the heaviest
    Using Statement II:
    Q > R > S > T > P,
    Q is the heaviest.

    Correct Option: C

    Using Statement I:
    Q > R > S > T > P,
    Q is the heaviest
    Using Statement II:
    Q > R > S > T > P,
    Q is the heaviest.
