m1= sc.nextByte();
System.out.println("Enter Your Marks in chemistry");
m2= sc.nextByte();
System.out.println("Enter your Marks in maths");
m3= sc.nextByte();
float avg= (m1+m2+m3)/3.0f;
System.out.println("Overall percentage is " + avg);
if (avg>=40 && m1>=33 && m2>=33 && m3>=33){

Q. Calculate Income Tax paid by an employee to the Government
public class exception {
public static void main(String[] args) {Scanner sc= new Scanner(System.in);
System.out.println("Enter Your Income in Lakhs per annum");
float tax = 0;
float income = sc.nextFloat();
if (income < 2.5){
tax = tax + 0;
}
else if (income>2.5f && income<=5f){
tax= tax +0.05f * (income - 2.5f);
}
else if (income>5f && income<=10f){
tax= tax +0.05f * (5.0f - 2.5f);
tax= tax +0.2f * (income - 5f);
}
else if (income>10.0f){
tax= tax +0.05f * (5.0f - 2.5f);
tax= tax +0.2f * (10.0f - 5f);
tax= tax +0.3f * (income - 10.0f);
}
System.out.println("The total tax paid by the employee is: " + tax);
