$$10$$

B
$$15$$

C
$$20$$

D
$$25$$

E
$$30$$

Solution

We know that
A car can travel $$240$$ miles on $$12$$ gallons of gasoline
$$\therefore$$ A car can travel $$1$$ miles on $$=\dfrac{12}{240}=\dfrac{1}{20}$$ gallons of gasoline (Unitary method)
In order to travel $$300$$ miles=$$\dfrac{1}{20}*300=15$$ gallons of gasoline is required.
Question 6
1 / -0

A group of $$24$$ students was polled as to whether they enjoy biology class, chemistry class, both, or neither. The results are shown in the table.
Given the data, Mark the correct statement.
Biology Chemistry
Enjoy $$14$$ $$18$$
Don't Enjoy $$10$$ $$6$$

A
The ratio of those who enjoy biology class to those who enjoy chemistry class is $$7:8$$

B
The ratio of those who enjoy chemistry class to those who don't enjoy chemistry class is $$9:4$$

C
The ratio of those who enjoy biology class to those who don't enjoy chemistry class is $$7:2$$

D
The ratio of those who don't enjoy biology class to those who enjoy chemistry class is $$5:9$$

Solution

(A) As per Statement and given data student who enjoy biology class are 14 and those who enjoy chemistry class is 18
Then ratio of   enjoy biology class and enjoy chemistry class =14:18=7:9
Then statement (A) is not correct
(B) As per Statement and given data student who enjoy chemistry class are 18 and those who don't enjoy chemistry class is 6
Then ratio of   enjoy biology class and enjoy chemistry class =18:6=3:1
Then statement (B) is not correct
(C) As per Statement and given data student who enjoy biology class are 14 and those who don"t enjoy chemistry class is 6
Then ratio of   enjoy biology class and enjoy chemistry class =14:6=7:3
Then statement (C) is not correct
(D) As per Statement and given data student who don"t enjoy biology class are 10 and those who enjoy chemistry class is 18
Then ratio of   enjoy biology class and enjoy chemistry class =10:18=5:9
Then statement (D) is correct .
Question 7
1 / -0

In $$7 : 2$$, the consequent is ______

A
$$7$$

B
$$2$$

C
$$72$$

D

A
$$8$$

B
$$4$$

C
$$\dfrac {4}{8}$$
