    Isn't it solved? Where are the solutions? Can we discuss the answers in some thread?

    @AKD: Once this is solved, I am planning to host it in my Quiz Engine. What say?

    @CP: The doc file only has questions. We need to discuss the solutions here. Can you give it a head start?

    I have more questions to share.

    PS: Some answers can be found elsewhere on the net, but the answers are different everywhere, so we need to find full-proof solutions here.

    Given 3 lines in the plane such that the points of intersection form a triangle with
    sides of length 20, 20 and 30, the number of points equidistant from all the 3
    lines is
    • 4
    • 1
    • 0
    • 3

    solution:
    answer is 1. and that point is called incentre.

    explanation:
    now take a triangle and inscribe a circle inside the triangle. the circle must touch all the sides of the triangle as shown in the figure.

    inradius(big)

    the radius of the circle will equidistant from all sides since the circle touches all three sides. there exists only one such point... 😀

    After the typist writes 12 letters and addresses 12 envelopes, she inserts the
    letters randomly into the envelopes (1 letter per envelope). What is the probability
    that exactly 1 letter is inserted in an improper envelope?
    • 11/12
    • 1/12
    • 0
    • 12/212

    answer: 0

    explanation:

    if one letter is inside a wrong envelope then there should be another one too which is in the wrong envelope. so the event of one error is impossible. so probability is 0.

    There are two water tanks A and B, A is much smaller than B. While water fills at
    the rate of one litre every hour in A, it gets filled up like 10, 20, 40, 80, 160 .. in
    tank B. (At the end of first hour, B has 10 litres, second hour it has 20, and so
    on). If 1/32 of B's volume is filled after 3 hours, what is the total duration required
    to fill it completely?
    • 10 hours
    • 8 hours
    • 7 hours
    • 9 hours

    answer:

    explanation:

    1/32 filled in 3 hours.
    in the next hour it will double the content in it...
    i.e. 1/16 in in 4 hours
    1/8 in in 5 hours
    1/4 in in 6 hours
    1/2 in in 7 hours
    full in 8 hours

    A circular dartboard of radius 1 foot is at a distance of 20 feet from you. You
    throw a dart at it and it hits the dartboard at some point Q in the circle. What is
    the probability that Q is closer to the center of the circle than the periphery?
    • 0.5
    • 0.25
    • 0.75
    • 1

    answer: .25

    explanation:
    the probability is= (area we need to consider)/ (total area of the dartboard) = (pi (r/2)^2)/(pi r^2) =.25



    P.S: these solutions may be wrong. so CEans please correct them if mistake found.

    one mistake in a problem that i solved.

    CIVILPRINCESS
    Given 3 lines in the plane such that the points of intersection form a triangle with
    sides of length 20, 20 and 30, the number of points equidistant from all the 3
    lines is
    • 4

    • 0
    • 3

    solution:
    answer is 1. and that point is called incentre.

    explanation:
    now take a triangle and inscribe a circle inside the triangle. the circle must touch all the sides of the triangle as shown in the figure.

    inradius(big)

    the radius of the circle will equidistant from all sides since the circle touches all three sides. there exists only one such point... 😀

    P.S: click the image for a larger size 😀

College Geometry, SAT Prep. Elearning</a>ere three epicentres and incentre are drawn. the question asks for the point which is at the same time equidistant from all sides. the epicentres are not equidistant from all sides.
    the excentre is also to be considered since it will be equidistant from all the sides when they are extended. this i had not thought..

    but now there is a new thing that i found.

    if it is an equilateral triangle then the no of excentre points would be three so the total points would be= 1(incentre)+3(excentre) =4.
    but for an isosceles triangle the no of excentres to be considered are just two. therefore no of points = 1+2 =3

    sorry for the confusion guys 😀

    • 18
    • 20
    • 0.0
    • 27
    the answer for this would be= 20


    reason: when we have it like x+y-z the maximum value would be 11 by cleverly placing the numbers. i'll post some examples for it in sometime. its just the same. just add the constant and 11. 😀

    For the FIFA world cup, Paul the octopus has been predicting the winner of each
    match with amazing success. It is rumored that in a match between 2 teams A
    and B, Paul picks A with the same probability as A's chances of winning. Let's
    assume such rumors to be true and that in a match between Ghana and Bolivia,
    Ghana the stronger team has a probability of 2/3 of winning the game. What is
    the probability that Paul will correctly pick the winner of the Ghana-Bolivia game?

    take one team proability i.e ghana sa 2/3.

    its complement is 1-(2/3)=1/3
    bolivia its winning proability is 1/3
    and losing is 2/3

    not the equation is p(winingof ghana and losing of bolivia)+p(wining of bolivia and losing of ghana)=(4/9)+(1/9)=(5/9)
    this is the ans

    cube prob:

    volume=5*5*5=125
    then reduce 2cm
    so v=3*3*3=27
    now 125-27=98
    find faces=98*6=588
    gn 4 faces are painted so area=4*25=100
    then 588-100=488

    balls prob:
    take 2 boxes
    transfer 9 red balls to another box so total balls in green box is(9+10)=19
    now p(red ball in box1)=1
    p(red ball in box2)=9/19

    p(selectin box)=1/2
    now eqn is
    1*1/2 + (9/19)*(1/2)

    verify the method frm ur frnds once........


    gn no cycle of handshakes so n-1=10-1=9

    36 ppl
    so the formula is n/3=36/3=12


    check balls prob. once
