    Finding The Angles


    At first look, it seems pretty easy but on the contrary, it is pretty tricky a question. So let us simplify it by dividing the triangle into three equal triangles (the triangles so formed if outer side is connected to the center of the circle) and then count the number of triangles in each part by taking two or more parts together.

    First, let us take the triangles in one part. There are 4 non-overlapping and 3 overlapping triangles.
    4 + 3 = 7
    7 * 3 = 21

    Next, if we take number of triangles by taking two parts together, there are 8 in total.
    8 * 3 = 24

    Lastly, the number of triangles if all three parts are taken together, there are a total of 2.

    21 + 24 + 2 = 47.

    Finding The Value Riddle

    Horse = 10
    Cowboy-Boot = 1
    HorseShoe= 2
    The Last equation = 21

    Detailed Explanation :
    3Horse = 30
    => Horse = 10 .....(1)

    1Horse + 2HorseShoe + 2HorseShoe = 18
    10 + 4HorseShoe =18
    HorseShoe = 2 .....(3)

    2HorseShoe - 2Cowboy-Boot = 2
    4 - 2Cowboy-Boot = 2
    => Cowboy-Boot = 1 ... (2)

    Cowboy-Boot+Horse*HorseShoe = 1+10*2

    Bat And Ball Riddle

    Hint: The answer isn't 10 cents.
    Here's the solution:

    Although $1.00 + $0.10 does equal $1.10, if you take $1.00 $0.10 you get $0.90, but the problem requires that the bat costs $1 more than the ball.

    So, the ball must cost $0.05, and the bat must cost $1.05 since $1.05 + $0.05 = $1.10


    Still not convinced? You can use algebra to solve the problem:

    First, lets set up the equation:

    x + ($1.00 + x) = $1.10

    $1.00 + 2x = $1.10

    2x = $1.10 $1.00

    2x = $0.101

    Finally, solve for x:

    x = $0.05

    Check your work:

    x + ($1.00 + x) = $1.10, so

    $0.05 + ($1.00 + $0.05) = $1.10
