(i) Correct code required for 'INTEREST RATE' button to display interest rate as per the above given criteria:

if (R1.isSelected() = = true)

T3.setText(" 4");

else if(R2.isSelected() = = true)

T3.setText("6");

if(R3.isSelected() = =true)

T3.setText("8");

(ii) Correct code required for 'SI' button

double amt = Double.parseDouble(T2.getText());

double int_rate =Double.parseDouble(T3.getText());

int year = Integer.parseInt(T4.getText());

double si = (amt*int_rate*year)/100;

T5.setText(" " + si);

(iii) t1.setText(" ");

t2.setText(" ");

t3.setText(" ");

t4.setText(" ");

t5.setText(" ");
