PROBLEMS ON AGES – Aptitude Interview Questions

PROBLEMS ON AGES – Aptitude Interview Questions  This blog explains about PROBLEMS ON AGES – Aptitude Interview Questions and is explained very well below : 1 . The present ages of three persons in proportions 4 : 7 : 9. Eight years ago, the sum of their ages was 56. Find their present ages (in years)       A. 8, 20, 28 B. 16, 28, 36 C. 20, 35, 45 D. None of these Answer: Option B Explanation: Let their present ages be 4x, 7x and 9x years respectively. Then, (4x – 8) + (7x – 8) + (9x – 8) = 56  20x = 80  x = 4.  Their present ages are 4x = 16 years, 7x = 28 years and 9x = 36 years respectively.      2. The age of father 10 years ago was thrice the age of his son. Ten years hence, father’s age will be twice that of his son. The ratio of their present ages is: A 5 : 2 B 7 : 3 C 9 : 2 D 13 : 4 Answer: Option B Explanation: Let the ages of father and son 10 years ago be 3x and x years respectively. Then, (3x + 10) + 10 = 2[(x + 10) + 10]  3x + 20 = 2x + 40  x = 20.  Required ratio = (3x + 10) : (x + 10) = 70 : 30 = 7 : 3. 3 . Six years ago, the ratio of the ages of Kunal and Sagar was 6 : 5.

Torvis Tech Interview Questions with Answers  This blog explains about Torvis Tech Interview Questions with Answers . It is explained below :    1 . How far can a dog run into the woods? Only halfway. If it runs more, then it would be running out of the woods.   2. why are the manhole covers round ? A number of possible explanations for why manhole covers are round include: A round manhole cover cannot fall through its circular opening, whereas a square manhole cover could fall in if it were inserted diagonally in the hole. Circular covers don’t need to be rotated or precisely aligned when placing them on the opening. A round manhole cover is easily moved and rolled. Human beings have a roughly circular cross-section. Round tubes are the strongest shape against the compression of the earth around them, so the cover of the tube would naturally be round as well. It’s easier to dig a circular hole. Round castings are much easier to manufacture using a lathe. 3 . You’re a new addition to the crayon box, what color would  you be and why? Answer  White color so that I can live forever  May be some dark color so that I will be sharp enough  4. A man ate 100 bananas in 5 days, each day eating 6 more than the previous day. How many bananas did he eat on the first day ? Suppose he ate x bananas on the first day then, =>   ( x )+ ( x+6 ) + ( x+6+6 ) + ( x+6+6+6 ) + ( x+6+6+6+6 ) = 100 =>5 x+60=100 =>5 x=40 =>x=8  Hence that guy ate 8 bananas on the first day   5 […]

TRICKY MATHS RIDDLES WITH ANSWERS  This blog explains about TRICKY MATHS RIDDLES WITH ANSWERS . It is explained clearly well below :    1. If 6 + 4 = 210         9 + 2 = 711         ? + ? = 113 Then what is the number ? ANSWER : It traces the pattern that ( a – b ) followed by (a + b )                                         ( 6 – 4 )( 6 + 4 ) = 210                                         ( 9 – 2 ) ( 9 + 2 ) = 711                                 So   ( 7 – 6 ) ( 7 + 6 ) = 113   2 . What will be the next number in the given sequence ?          0  1   3  2  6  3  9  4  12   5   ? ANSWER : Let us consider the numbers to be  “ abcdefghijkl” Here the numbers  “ a , c , e , g , i , k ” are consecutive numbers and the numbers “ b , d , f , h , j , l ” are multiples of 3 . So the next number will be 15  3.  If   1  +  4 =  5           2  +  5  = 12            3  +  6 = 21 Then 8 + 11 = ?

Cryptography: Roles, Market, and Infrastructure Cryptography is a technology that can play important roles in addressing certain types of information vulnerability. As a technology, cryptography is embedded into products that are purchased by a large number of users; thus, it is important to examine various aspects of the market for cryptography. So basically, cryptography is used almost exclusively in security related areas.  This is useful for sending messages, making sure only paying customers can install software, and is responsible for preventing people from “jailbreaking” their phone. _______________________________________________________________________________ 2. Mention five database system u know of? The systems are listed by type: relational(R), extended-relational(X), object-relational(OR), object-oriented(OO), network(N) and hierarchical(H). In such a case the DBMS type is specified by more than one designation.

Test Driven Development – Brief Explanation

Test Driven Development – Brief Explanation  This blog explains about Test Driven Development – Brief Explanation . It is explained clearly well below :                                                                   Test Driven Development TDD or Test Driven Development is a process for testing the functionality of the code.  It is a repeated process where the testscript is written first for the particular requirement then the business logics were driven using the test scripts. Main Moto of Test Driven Development: TDD is used mainly to enable the developer to think in QA perspective and write the test cases or test scripts before writing the functional code. Is TDD is different from Unit testing? Yes, In normal unit testing the functional code were developed and then unit testing ( decision coverage, branch coverage, loop testing ) were performed while in TDD first the test scripts or test cases are written using the selected requirement then the functional code is developed using the test scripts. Understanding TDD: In TDD the initial test scriptmust fail, then the developers should write logic for the particular requirement and make the test case to pass.                                                                    Note: TDD is not a framework/ tool/ Technology, it is a thought process which makesdevelopers to write test cases for the particular functionality. Step 1:  Add a test script in a class, corresponding to the particular requirement. Step 2:  Run the test script, eventually […]
