Coding Questions and Answers pdf

Cognizant GenC has changed the exam pattern for the year 2023. They have divided the written test into two rounds:

Round-1(Aptitude Assessment)
Round-2(Communication Assessment)

Hence, Coding is no more a part of Cognizant GenC exam.

Question-1

Problem Statement – Write a program to calculate the fuel consumption of your truck.The program should ask the user to enter the quantity of diesel to fill up the tank and the distance covered till the tank goes dry.Calculate the fuel consumption and display it in the format (liters per 100 kilometers).

Convert the same result to the U.S. style of miles per gallon and display the result. If the quantity or distance is zero or negative display ” is an Invalid Input”.

[Note: The US approach of fuel consumption calculation (distance / fuel) is the inverse of the European approach (fuel / distance ). Also note that 1 kilometer is 0.6214 miles, and 1 liter is 0.2642 gallons.]

The result should be with two decimal place.To get two decimal place refer the below-mentioned print statement :

float cost=670.23;

System.out.printf(“You need a sum of Rs.%.2f to cover the trip”,cost);

Sample Input 1:

Enter the no of liters to fill the tank

20

Enter the distance covered

150

Sample Output 1:

Liters/100KM

13.33

Miles/gallons

17.64

Explanation:

For 150 KM fuel consumption is 20 liters,
Then for 100 KM fuel consumption would be (20/150)*100=13.33,
Distance is given in KM, we have to convert it to miles (150*0.6214)=93.21,
Fuel consumption is given in liters, we have to convert it to gallons (20*0.2642)=5.284,
Then find (miles/gallons)=(93.21/5.284)=17.64

Sample Input 2:

Enter the no of liters to fill the tank

-5

Sample Output 2:

-5 is an Invalid Input

Sample Input 3:

Enter the no of liters to fill the tank

25

Enter the distance covered

-21

Sample Output 3:

-21 is an Invalid Input

Question-5

Problem Statement – In a theater, there is a discount scheme announced where one gets a 10% discount on the total cost of tickets when there is a bulk booking of more than 20 tickets, and a discount of 2% on the total cost of tickets if a special coupon card is submitted. Develop a program to find the total cost as per the scheme. The cost of the k class ticket is Rs.75 and q class is Rs.150. Refreshments can also be opted by paying an additional of Rs. 50 per member.

Hint: k and q and You have to book minimum of 5 tickets and maximum of 40 at a time. If fails display “Minimum of 5 and Maximum of 40 Tickets”. If circle is given a value other than ‘k’ or ‘q’ the output should be “Invalid Input”.

The ticket cost should be printed exactly to two decimal places.

Sample Input 1:

Enter the no of ticket:35
Do you want refreshment:y
Do you have coupon code:y
Enter the circle:k

Sample Output 1:

Ticket cost:4065.25

Sample Input 2:

Question-9

XYZ Technologies is in the process of increment the salary of the employees. This increment is done based on their salary and their performance appraisal rating.

If the appraisal rating is between 1 and 3, the increment is 10% of the salary.
If the appraisal rating is between 3.1 and 4, the increment is 25% of the salary.
If the appraisal rating is between 4.1 and 5, the increment is 30% of the salary.

Help them to do this, by writing a program that displays the incremented salary. Write a class “IncrementCalculation.java” and write the main method in it.

Note : If either the salary is 0 or negative (or) if the appraisal rating is not in the range 1 to 5 (inclusive), then the output should be “Invalid Input”.

Sample Input 1 :

Enter the salary

8000

Enter the Performance appraisal rating

Sample Output 1 :

8800

Sample Input 2 :

Enter the salary

Question-12

Problem Statement – Mayuri buys “N” no of products from a shop. The shop offers a different percentage of discount on each item. She wants to know the item that has the minimum discount offer, so that she can avoid buying that and save money.
[Input Format: The first input refers to the no of items; the second input is the item name, price and discount percentage separated by comma(,)]
Assume the minimum discount offer is in the form of Integer.

Note: There can be more than one product with a minimum discount.

Sample Input 1:

4

mobile,10000,20

shoe,5000,10

watch,6000,15

laptop,35000,5

Sample Output 1:

shoe

Explanation: The discount on the mobile is 2000, the discount on the shoe is 500, the discount on the watch is 900 and the discount on the laptop is 1750. So the discount on the shoe is the minimum.

Sample Input 2:

4

Mobile,5000,10

shoe,5000,10

WATCH,5000,10

Laptop,5000,10

Sample Output 2:

Question-14

Problem Statement – Bela teaches her daughter to find the factors of a given number. When she provides a number to her daughter, she should tell the factors of that number. Help her to do this, by writing a program. Write a class FindFactor.java and write the main method in it.
Note :

If the input provided is negative, ignore the sign and provide the output. If the input is zero
If the input is zero the output should be “No Factors”.

Sample Input 1 :

54

Sample Output 1 :

1, 2, 3, 6, 9, 18, 27, 54

Sample Input 2 :

-1869

Sample Output 2 :

1, 3, 7, 21, 89, 267, 623, 1869
