1. Create an application named Numbers whose main() method holds two integer variables. Assign
values to the variables. Pass both variables to methods named sum () and difference(). Create the
methods sum() and difference(); they compute the sum of and difference between the values of two
arguments, respectively. Each method should perform the appropriate computation and display the
results. Save the application as Numbers.cs
In your own words, briefly explain in a paragraph how books can be selected for teaching in a way that encourages respect for diversity and creates an atmosphere of safety, equality and inclusion in the classroom.
Write an application for a furniture company; the program determines the price of a table. Ask the user to choose 1 for pine, 2 for oak, or 3 for mahogany. The output is the name of the wood chosen as well as the price of the table. Pine tables cost R 100, oak tables cost R 225, and mahogany tables cost R 310. If the user enters an invalid wood code, set the price to 0 and allow the user to select an option up to 3 times . Save the file as Furniture.java.

A work of 657 J is done on a system that releases 434 J of
heat. What is the energy change in the system?
1 kg of steam at 7 bar, entropy 6.5 kJ/kg K, is heated reversibly at constant pressure until the temperature is 250℃. Calculate the heat supplied.
1 kg of steam at 100 bar and 370℃ expands reversibly in a perfectly thermally insulated cylinder behind a piston until the pressure is 38 bar and the steam is then dry saturated. Calculate the work done
The production costs of a factory are given as follows:
Rupees
Direct Wages 90,000
Direct Materials 1,20,000
Production Overheads: Fixed 40,000
Variable 60,000
During the forthcoming year it is anticipated that:
a) Average rate for direct labour remuneration will fall from Rs.0.90 per hour
to Rs.0.75 per hour.
b) Production efficiency will be reduced by 5%.
c) Price per unit of direct material and of other materials and services which
comprise overheads will remain unchanged.
d) Direct labour hours will increase by 33.33%. Draw up a budget.
