Six to ten days 65 paisa per day
above 10 days 80 paisa per day.
Design a program to calculate the fine assuming that a book is returned N days late.
Q2 Generate the pattern [15]

***
*****
*******
*****

Q3 WAP to accept a number and check whether the number is perfect number or not. A number
is called perfect number, if the sum of all factors (except number itself) of the number is equal to
that number. (For e.g. 6 is a perfect number. Factors are 1, 2 & 3 and the sum is 1+2+3 = 6.)
[15]
Q4 Find the sum of the series. [15]

S = (X+1)2+(X+2)3+(X+3)4+(X+4)5+…………… +(X+N)N+1
Q5 The volume of solids, viz. cuboid, cylinder and cone can be calculated by the Formula:
[15]
1. Volume of a cuboid
2. Volume of a cylinder
3. Volume of a cone ( ) ( )
Using a switch case statement, write a program to find the volume of different
solids by taking suitable variables and data types.
Q6 A special two-digit number is such that when the sum of its digits is added to
the product of its digits, the result is equal to the original two-digit number.
Example: Consider the number 59. [15]

Sum of digits = 5 + 9 = 14
5
Product of digits = 5 * 9 = 45
Sum of the sum of digits and product of digits = 14 + 45 = 59
Write a program to accept a two-digit number. Add the sum of its digits to the
product of its digits. If the value is equal to the number input, then display the
message "Special 2 - digit number" otherwise, display the message "Not a special
two-digit number".
