Answer:
The correct answer to this question is option (1).
Explanation:
Let x1 = Is number of pages that printer A can print in page/minute.
thus x1 + 5 = Is number of page that printer B can print in page/minute.
As printer A finishes his work in 60 min. So the task has 60x1 pages. As printers A and B both finish that task in 24 minutes. So the equation can be given as:
60x1 = 24x1 + 24(x1 + 5)
60x1 = 24x1 + 24x1 + 120
60x1=48x1 + 120
60x1-48x1=120
12x1=120
x1=120/12
x1=10
put the value of x1 in to (60x1). Therefore, the task has 60(10) = 600 pages. the task contains 600 pages.
So the answer to this question is option (1).
Answer:
A) Switch
Explanation:
In Java and most programming Languages, A Switch Statement provides a multi branch statements which provides a more flexible way for transfer of execution to the branch that fulfills the condition of the expressed value. This is a better way of handling if...elseif....else statements. In this way, a variable is tested for equality against some values. Variables used in switch expressions can only be primitives (int, byte, char), enums and strings. A switch statement has
1. A default statement (optional), appears at the end of the switch and acts as the else condition.
2. A break statement which terminates the switch when reached.
The syntax of a switch statement is given below:
switch(expression) {
case x:
// code block
break;
case y:
// code block
break;
default:
// code block
}
