• None of these

• 240

Answer 1

1. Variables are that part of the equation whose value is not fixed it's generally in letter form either independent or linked with a coefficient number. variable keeps on changing based on the change in criteria so it can't be only number.

Thus the correct Option is-------------FALSE.

2.

American Airlines reduced its round trip fare from Boston to New York by $45.

So the original price will be the new price + amount reduced.

Original price = $ 139 + $ 45 = $ 184.

Original price = $ 184.

3.

Existing salary = $ 85,000 and raise in salary = $ 3000.

So the percentage increase = Increment in salary / Existing salary.

Raise percentage of old salary = $ 3000 / $ 85,000

Raise percent of old salary = 3.53%.

4.

Percentage refers to the part of 100th and not of 1000.

So 40 % is 40 parts out of 100 and not 1000.

Thus the correct Option is-------------False.

5.

Fraction 1/7 in percentage :

Percent = (1/7 )× 100

Percent = 14.3%.

6.

Total cars sold = 360 cars , here if Ranger sells 1 car so Rick will sell 5 cars.

Proportional analysis is made with total of the criteria, i.e 1 + 5 = 6.

So Toyota's Ranger will sell = 360 × ( 5/6).

Ranger will sell Toyota's = 300

Thus the correct Option is-------------C i.e 300
