The following Orcale Interview Puzzles will help you enhance your skills and will offer you better confidence while giving the interview.
==>(1/7+1/7^2+1/7^3+1/7^4+1/7^5+......) + (1/7^2+1/7^4+ 1/7^6+.......)
Thus we have two GP series one with a=1/7 and r=1/7
And the second one with a=1/7^2 and r= 1/7^2
Sum of GP to infinity (when r is small) = a/1-r
Hence sum of expression = (1/7/1-1/7) + (1/7^2/1-1/7^2) = (1/6) + (1/48) = 3/16
Let us begin solving the problem by denoting a simple letter to all the three sides of the triangle
Let base be (b), perpendicular be (p) and hypotenuse be (h)
Now glance over the given condition according to which h^2 = 2b*p
or b^2 + p^2 = 2b*p
or (b-p)^2 = 0
or b = p
Thus the triangle is an isosceles one with the angle = 45 degrees
So, option (a) is correct
This is quite an easy question which is used generally as a warm up question during the interviews.
It is true that only three points are equidistant from each other. But take a paper and draw four points in the shape of a pyramid. You can definitely draw four equidistant points. Thus all you have to do as a builder is build the buildings in the same manner. In this way, one building will be placed in between the three buildings.
You are given with two dices. You can write numbers from 0 to 9 on each of the face of the two dices. All you have to make sure is that you should be able to represent any day of the month using the two dices from 1 to 31.
Suppose if you have to represent 3rd of the month, then one dice must have 0 and one dice must have 3. How can you make it possible for all the days?
Please keep in mind that you will have to show 11 and 12 as well, thus 1 and 2 must be present in both the dices. In the same manner, to show 01, 09, 0 must be present in both the dices. Now if you are wondering how you will show 9 as we have not written it in any of the faces of the dices, the trick is to reverse 6 to show it as 9.
You may now try any day of the month and you will easily be able to represent it through the dices.
Let the age of the daughter five years ago be x. Then Katie's age will be 5x.
Daughter = x + 5
Katie = 5x + 5
After 5 years
Daughter's age = x + 10
Katie's age = 5x + 5 + 5 = 5x + 10
Now consider the question again. We know that five years from present, Katie's age will be 8 less than three times the corresponding age of her daughter. Thus if we add eight to the Katie's age, five years from now and make her daughter's age 3 times more, we can easily find out x.
This question is one of the most common interview question. The most common answer of the question is sixty which is completely wrong. The second most common answer of this interview question is 10 which is wrong as well.
What we have is
6 fishermen catches 6 fishes in 6 minutes
If you offer them 10 times as much as time, they will surely catch 10 times as much as fishes as well
Thus the same six fishermen will be able to catch 60 fishes in 60 minutes.
You can also thing this in the unitary method.
If six fishermen catches 6 fishes in 6 minutes
Then, one fisherman will catch one 1 fish in 6 minutes
Thus in sixty minutes, one fisherman will catch 10 fishes (10 times the time, ten times the fishes).
Thus the right answer is six.
