Explanation / Answer

11.

var orderTotal = 200;
if (orderTotal > 200) { // 200 >200 false
    discountAmount = orderTotal * .3;

} else if (orderTotal > 100) { // 100 >200 false
    discountAmount = orderTotal * .2; // discountAmount = 200 * .2 = 40

Option 3

12.

entry=9 and number =3

9/3 == 3

if ((entry > 9) || (entry/number == 3)) { // (9 > 9 => false || 3 == 3 =>true) since use OR logic it is true

{
      entry--; // entry = 9-1 =8
}

Option 2

13.

totalMonths = 13

var years = parseInt ( totalMonths / 12 ); // 13/12 = 1 (since int data type)
var months = totalMonths % 12; // 13%12 = 1

if ( years == 0 ) { // False
   

else if ( months == 0 ) // False

else {
    alert ( years + " years, and " + months + " months."); // It print 1 years, and 1 months

}

Option 1

14.

if (pay >= 500) { // more than 500
     tax_rate = 0.3;
} else if (pay >= 300) { // 300 - 499
     tax_rate = 0.2;
} else if (pay >= 100) { // 100-299
     tax_rate = 0.1;
}

Option 2

15.

var percent = 0.54;
var isValid = true;
var counter = 1;
if ((percent > 0.50) && (isValid == true)) { ((0.54 > 0.50) =>True and (true== true)=>True) =>True
     counter += 2; // counter = 1+2 = 3
     if (isValid == true) { // (true== true)=>True
          counter++;  counter = 3+1 = 4
     }
