    I know 24th answer!!

    I will switch on one bulb and stay for some time , then i will switch it off!

    I will switch on the another one.

    I will enter the room.

    The Switch which I on corresponds to the bulb which is glowing.

    The bulb which is hot corresponds to first switch.

    And the last one to the last switch.

    13. How to measure 9 minutes using only a 4 minute and 7 minute hourglass? Asked at Bank of America
    1) Start with both the hourglasses in position.
    2) At the end of 4th minute (determined by 4 minute hourglass) invert 4 minute hourglass.
    3) At the end of 7th minute (determined by 7 minute hourglass) invert both the hourglasses. Now 4 minute hourglass is capable of measuring 1 minute.
    4) At the end of 8th minute (determined by twicked capability of 4 minute hourglass) invert 7 minute hourglass. This 7 minute hourglass had collected 1 minute.
    5) Using the collected 1 minute in 7 minute hourglass, last minute (of 9 minutes) is measured.

    it can also be done as following:

    1) start with both the hourglasses in position.

    2)At the end of 4th minute(d etermined by 4 minute hourglass)invert the 4 minute hourglass.

    3)At the end of 7th minute( determined by the 7 minute hourglass) invert the 4 minute hourglass. Now 4 minute hourglass is capable of measuring 1 minute.

    4)At the end this 1 minute invert the 4 minute hourglass.

    5)Again at the end of 4 minutes invert the 4 minute houglass.

    6)Now at the end of these 4 minutes,
    9 minutes are certainly measured!!!!!

    answer to ques number 15.

    well this one is simple!!!!

    total number of events = 36
    number of favourable events= 2 (5,6)(6,5)

    thus the probability will be = 2/36 = 1/18!!!

    so simple..that means i may got a placement!!!

    answer to ques no. 5:

    the speed of two cars are 60mph and 30mph
    well to end the race at the same time the car travelling with slower speed mus have to accelerate!!!!

    the desired acceleration can be find out as follows:

    suppose the distance to the finish line be 'L'
    and as we know that the slower car is moving with 30mph = u(let)
    now time taken by the car moving at 60mph will be
    t = L/60 hrs

    so by using the following formula we can calculate the acceleration needed:

    L = ut2+(1/2)at2 here 'a' is the desired acceleration

    now on putting values in the above formula..we get

    a = L/3600

    so the car moving at 30mph must accelerate at the rate of L/3600 to finish the race at the same time!!!!😁

    correct me if am wrong!!!!
