Capgemini Puzzles Questions and Answers

Puzzles Questions and Answers:-

1.A seller has some quantity of rice with him. The seller offered his customer that if he/she buys half of the rice he has, he will give half kg of rice as a discount. The first customer accepts his offer and he purchased half of the rice and get half kg as extra. After selling the rice to the first customer he again makes the same offer for the second customer, and so on. The seller left with no quantity of rice after he made the fifth transaction.

Solution:-

Let us calculate the total kg of rice which seller has before each customer came for purchasing.

  • Before fifth customer: (1/2 kg as a discount)*2 = 1
    So before dealing with fifth customer seller should have 1kg.
  • Before fourth customer: (1+(1/2 as a discount))*2 = 3
    So before dealing with fourth customer seller should have 3kg.
  • Before third customer: (3+(1/2 kg as a discount))*2 = 7
    So before dealing with third customer seller should have 7 kg.
  • Before second customer: (7+(1/2 as a discount))*2 = 15
    So before dealing with second customer seller should have 15 kg.
  • Before First customer: (15+(1/2 kg as a discount))*2 = 31
    So before dealing with first customer seller should have 31 kg.

Q.2-You have 4 bottles of milk. One of them is poisonous while the other 3 are non-poisonous. There is a rat which dies exactly after 10 hours of drinking the poisoned bottle. You have a clock that measures time only in hours. Suggest an optimal strategy to identify the poisoned bottle within 24 hours.

Ans-At the beginning of the first hour feed the rat the Ist bottle. At the start of 2nd-hour feed, the 2nd one and similarly at the start of 3rd-hour feed, the 3rd bottle. If the rat dies after exactly 10 hrs, the first bottle
is poisonous. If it dies after 11 hours, 2nd one contains poison else the 3rd one is poisonous. In this way,
after exactly 12 hours you would be able to determine the poisonous bottle.

Technical Interview Questions and Answers

In Technical interview round,You should be concerned for your Final Year Projects, Technical Subjects etc.Your Resume is the most important thing,they will judge you according to your resume.Be Prepared for everyhing that you have mentioned in your resume.

Few question that have been frequently asked in the technical round of Coding Branch are:

1. What is your strongest programming language (Java, ASP, C, C++, VB, HTML, C#, etc.)? 

Ans-You should decide your Favorite programming language and be prepared based on that question.

2.What are the different storage classes in C ?

Ans-There are four types of storage classes in C. They are extern, register, auto and static

3.What are macros? what are its advantages and disadvantages? 

Ans-Macros are processor directive which will be replaced at compile time.
The disadvantage with macros is that they just replace the code they are not function calls. similarly the advantage is they can reduce time for replacing the same values.

4.Difference between pass by reference and pass by value? 
Ans-Pass by value just passes the value from caller to calling function so the called function cannot modify the values in caller function. But Pass by reference will pass the address to the caller function instead of value if called function requires to modify any value it can directly modify.

5. What is ponter?

Pointer is a variable in a program is something with a name, the value of which can vary. The way the compiler and linker handles this is that it assigns a specific block of memory within the computer to hold the value of that variable.

 

6.what is function overloading 

   Function overloading is a feature of C++ that allows us to create multiple functions with the same name, so long as they have different parameters.Consider the following function:
int Add(int nX, int nY)
{
return nX + nY;
}

7. Tell me something about abstract classes?

An abstract class is a class which does not fully represent an object. Instead, it represents a broad range of different classes of objects. However, this representation extends only to the features that those classes of objects have in common. Thus, an abstract class provides only a partial description of its objects.

8.What is data structure?
A data structure is a way of organizing data that considers not only the items stored, but also their relationship to each other. Advance knowledge about the relationship between data items allows designing of efficient algorithms for the manipulation of data.

9.Write a Insertion Sort Code in C?

 

  • #include <stdio.h>
  • int main()
  • {
  •   int n, array[1000], c, d, t;
  •   printf("Enter number of elements\n");
  •   scanf("%d", &n);
  •   printf("Enter %d integers\n", n);
  •   for (c = 0; c < n; c++)
  •     scanf("%d", &array[c]);
  •   for (c = 1 ; c <= n - 1; c++) {
  •     d = c;
  •     while ( d > 0 && array[d-1] > array[d]) {
  •       t          = array[d];
  •       array[d]   = array[d-1];
  •       array[d-1] = t;
  •       d--;
  •     }
  •   }
  •   printf("Sorted list in ascending order:\n");
  •   for (c = 0; c <= n - 1; c++) {
  •     printf("%d\n", array[c]);
  •   }
  •   return 0;
  • }

Technical Interview Questions and Answers for Non-Coding Branch

Few question that have been frequently asked in the technical round of Non-Coding Branch are:

1. What is Control System?

In a System the output and inputs are interrelated in such a manner that the output quantity or variable is controlled by input quantity, then such a system is called Control System.
The output quantity is called controlled variable or response and the input quantity is called command signal or excitation.

2. Why thyristor is considered as Charge controlled device?

During the triggering process of the thyristor from forward blocking state to forward conduction state through the gate signal, by applying the gate signal (voltage between gate and cathode) increases the minority carrier density in the p-layer and thereby facilitate the reverse break over of the junction J2 and thyristor starts conducting. Higher the magnitude of the gate current pulse, lesser is the time required to inject the charge and turning on the scr. By controlling the amount of charge we can control the turning on time of the scr.

3. What is reverse power relay?

Reverse Power flow relay are used in generating stations's protection. A generating stations is supposed to fed power to the grid and in case generating units are off,there is no generation in the plant then plant may take power from grid. To stop the flow of power from grid to generator we use reverse power relay.

4. What will happen if DC supply is given on the primary of a transformer?

Mainly transformer has high inductance and low resistance.In case of DC supply there is no inductance ,only resistance will act in the electrical circuit. So high electrical current will flow through primary side of the transformer.So for this reason coil and insulation will burn out.

5. What is the difference between MCB & MCCB, Where it can be used?

MCB is miniature circuit breaker which is thermal operated and use for short circuit protection in small current rating circuit. MCCB moulded case circuit breaker and is thermal operated for over load current and magnetic operation for instant trip in short circuit condition.under voltage and under frequency may be inbuilt. Normally it is used where normal current is more than 100A.

6. Two bulbs of 100w and 40w respectively connected in series across a 230v supply which bulb will glow bright and why?

Since two bulbs are in series they will get equal amount of electrical current but as the supply voltage is constant across the bulb(P=V^2/R).So the resistance of 40W bulb is greater and voltage across 40W is more (V=IR) so 40W bulb will glow brighter.

7. What is the difference between synchronous generator & asynchronous generator?

In simple, synchronous generator supply's both active and reactive power but asynchronous generator(induction generator) supply's only active power and observe reactive power for magnetizing.This type of generators are used in windmills.

8. What is Automatic Voltage regulator(AVR)?

AVR is an abbreviation for Automatic Voltage Regulator.It is important part in Synchronous Generators, it controls theoutput voltage of the generator by controlling its excitation current. Thus it can control the output Reactive Power of the Generator.

9. What is the principle of motor?
Whenever a current carrying conductor is placed in an magnetic field it produce turning or twisting movement is called as torque.
