Computer Application is very interesting subject to learn as it include algorithms, logics, coding part etc, which generally seems to very interesting to learn. But for the purpose of Board Exam preparation it demand proper attention to understand the concept behind every topic. Than only one is able to gain good marks in Board Exams. Indian Council of Secondary Education is one of the most reputed private boards of India that serve quality education. The main objective of ICSE Computer Application Sample Papers is to make students about the paper pattern and the type of questions asked in the exam. I hope this paper will help you in this regard. To perform well in your Board exam you can also take help from ICSE Class 10 Physics Sample Papers.

SECTION B (60 Marks)
(a) Define a class taximeter having the following description:
Data members/instance variables
int taxino – to store taxi number
String name – to store passenger’s name
int km – to store number of kilometres travelled
taximeter() — constructor to initialize taxino to 0, name to “ ”and b to 0.
input() – to store taxino,name,km
calculate() – to calculate bill for a customer according to given conditions
kilometers travelled(km) Rate/km
≤ 1 km Rs 25
1 < km ≤ 6 Rs 10
6 < km ≤ 12 Rs 15
12 < km ≤ 18 Rs 20
>18 km Rs 25
display()- To display the details in the following format
Taxino Name Kilometres travelled Bill amount
Create an object in the main method and call all the above methods in it. [15 Mark]
(a) Write a menu driven program to find the sum of the following series depending on the user choosing 1 or 2
1. S=1/4+1/8+1/12………upto n terms
2. S=1/1!-2/2!+3/3!…….upto n terms
where ! stands for factorial of the number and the factorial value of a number is the
product of all integers from 1 to that number, e.g. 5! = 1 × 2 × 3 × 4 × 5.
(use switch-case). [15 Mark]
