    There is a bacteria which has the probability of die 1/3 of its total number or it may tripled.
    Find out the probability
    A. P=1/3+(2/3*p^3)
    B. P=2/3+(2/3*p^3)
    C. P=2/3+(1/3*p^3)
    D. P=2/3+(2/3*p^3)

    Worst Case Scenario:
    First he takes all of the 40 gloves, then he takes all of the 27 gloves and then he needs to take 2 more gloves to have a pair of each colour.
    So, total gloves = 40+27+2 = 69 gloves
    Here, there is no mention of how many gloves are taken in one time.
    Suppose we need to take two gloves at a time,
    then, it would be 40 + (27+1) + 2 = 70 gloves (as gloves would be taken in a pair)

    Total cubes = 10*5*5 = 250 cubes
    In order to be a perfect cube, 10*10*10 cubes need to be used
    So, 1000-250 = 750 cubes need to be used!
    Hence, option 2

    The double declining method is one where the depreciation is more in the initial period.
    In the first year,
    Depreciation = 2*(16000/5) = 6400
    In the second year
    Depreciation = 2(16000-6400)/5 = 3840
    So,
    Total accumulated Depreciation = 10240
    So, Book Value = 16000-10240 = 5760

    Can't say
    Suppose 1 pillar = 1m (say)
    Let Jerry = 1m (say)
    Then, according to the given condition,
    Joe > Jerry+2pillar
    Jerry + 3 pillars = 1 + 3 = 4
    So, Joe can be = 5 m
    Now, according to the second condition,
    Joe + 2 pillar > Kirsten
    So, 5+ 2 = 7 is higher than Kirsten's height
    So, if Kirsten = 0.5, Kirsten is smaller than Jerry
    If Kirsten = 2, its the other way around!

    There are two possibilities
    Case 1: _ D A E _
    Case 2: _E _ D A
    The blanks can be filled by the two boys that are left
    Given proper options, we can choose the appropriate one!

    Selection of 3 alphabets from 26 alphabets can be done in 26*25*24 ways.
    Selection of 3 numbers from 10 numbers can be done in 10*9*8 ways.
    Numbers/Alphabets can be either at the beginning or at the end which gives 2 more possibilities.
    Multiplying all we can decipher that the result shoud have three zeroes at the end.

    This question falls under the category of different things getting distributed to different people.
    Given 3 different ice creams there are 23 of selection possible. This is because none of them can be selected(nC0), one of them selected(nC1) , two of them selected(nC2) and three of them selected(nC3). Here n =3, thus there are 23 possibilities.
    As per the question at least one of them has to be selected. Therefore nC0 selection has to be excluded, 23-1.
    Thus for all the items the final product becomes as , (23-1)*(24-1)*(22-1) = 315.
