3.   TSEB charges their consumer according to the tariff chart given below:

Units Consumed        Charges

Up to 50 units         Free

51-100                  ₹   3

101-250                     ₹   5

252-500                     ₹   7

Above 500              ₹ 10

Write a program to calculate the total amount to be paid, taking number of units as input.

4.   A courier service provides a speed service for any letter/parcel to Mumbai, which delivers on the same day as per the rates given below:

Up to 100 gms : ₹ 80

For each additional 100 gm or part thereof ₹ 40

Sample Input: 320

The charge:  Up to 100 gms          =   ₹    80

For next 200 gms     =  ₹    80

For next 20 gms        =  ₹    40

 Total charge :             ₹  200

Write a program to calculate the total amount to be paid, taking weight of the letter/parcel as input.

5.   Write a Menu-Driven program to input/assign/store 2 numbers and perform the following mathematical operations on the two variables as given below in the menu...

1. Addition (+)

2. Subtraction (-)

3. Multiplication (x)

4. Division (/)

5. Average(a)

6. Power (xy)

6.   Create overloaded methods named void calcVolume (), that has been overloaded to perform the following functions:

·         Volume of Sphere

·         Volume of Cylinder

·         Volume of Cone

7.   Write a menu-driven program in Java to display the above 3 menus and execute the overloaded methods and display the volume in the respective functions,

·         calcVolume (double) for Sphere,

·         calcVolume (double, double) for Cylinder and

·         calcVolume (float, float) for Cone.

8.   Write a function named int sortDigit(int) in Java to pass an integer number as argument that might contain any number of digits, and sort each individual digits of the number in ascending order and return the same, (without implementing arrays)

e.g. Sample Input:   4967

     Sample Output:       4679

     Sample Input:     1205

     Sample Output:       0125

9.   Write a Program in Java to accepts an integer and count the factors of the number.

10.   Write a Program in Java to accepts 3 digits number or more and display the Sum of first and last digit.

11.   Write a Program in Java to enter a number and check whether the number is Twisted Prime Number or not.

Twisted Prime Number: If a number is prime, and its reverse number is also prime, then it is called Twisted prime number.

Example: - 37 is prime number, and its reverse order is 73 and 73 is also prime.

12.   Write a menu driven program to accept a number and check and display whether it is a prime number or not OR an Automorphic number or not. (Use switch-case statement).

(a) Prime Number: A number is said to be a Prime Number if it is divisible only by 1 and itself and not by any other number.

Example : 3, 5, 7, 11, 13 etc.

(b) Automorphic number: An Automorphic Number is the number which is contained in the last digit(s) of its square.

Example: 25 is an Automorphic Number as its square is 625 and 25 is present as the last two digits.

13. Write a Program in Java to input the total amount in Rupees and find out the denominations in least possible numbers of all possible currency notes (i.e. ₹ . 500/-, ₹ . 200/-, ₹ . 100/-,₹ . 50/-, ₹ . 20/-, ₹ . 10/-, ₹ . 5/, ₹ . 2/-,  ₹  1/- for the amount entered by the user.
