## Best PSAT Math Prep Resource for 2020

1- A
Percent of cities in the type of pollution A:$$\frac{6}{10}×100=60\%$$
Percent of cities in the type of pollution C: $$\frac{4}{10}×100=40\%$$
Percent of cities in the type of pollution E:$$\frac{9}{10}×100=90\%$$

2- A
Let the number of cities should be added to type of pollutions $$B$$ be $$x$$. Then:
$$\frac{x+3}{8}=0.625→x+3=8×0.625→x+3=5→x=2$$

3- C
Let’s find the mean (average), mode and median of the number of cities for each type of pollution.
Number of cities for each type of pollution: $$6, 3, 4, 9, 8$$
$$Mean (Average) = \frac{sum \space of \space terms}{number \space of \space terms}=\frac{6+3+4+9+8}{5}=\frac{30}{5}=6$$
Median is the number in the middle. To find median, first list numbers in order from smallest to largest.
$$3, 4, 6, 8, 9$$
Median of the data is 6.
Mode is the number which appears most often in a set of numbers. Therefore, there is no mode in the set of numbers.
Median = Mean, then, a=c

4- C
The ratio of boy to girls is $$4:7$$. Therefore, there are 4 boys out of 11 students. To find the answer, first divide the total number of students by 11, then multiply the result by 4.
$$44 ÷ 11 = 4 ⇒ 4 × 4 = 16$$
There are 16 boys and $$28 (44 – 16)$$ girls. So, 12 more boys should be enrolled to make the ratio $$1:1$$

5- A
$$AB = 12$$ And$$AC = 5$$
$$BC = \sqrt {(12^2+5^2 )}=\sqrt{(144+25)}=\sqrt {169}=13$$
Perimeter $$= 5 + 12 + 13 = 30$$
$$\frac{5×12}{2}=5×6=30$$
In this case, the ratio of the perimeter of the triangle to its area is: $$\frac{30}{30} = 1$$
If the sides $$AB$$ and $$AC$$ become twice longer, then:
$$AB=24 \space And \space AC=10$$
$$BC=\sqrt{(24^2+10^2 )}=\sqrt{(576+100)}=\sqrt {676}=26$$
Perimeter$$= 26 + 24 + 10 = 60$$
$$\frac{10×24}{2}=10×12=120$$
In this case the ratio of the perimeter of the triangle to its area is:
$$\frac{60}{120}=\frac{1}{2}$$

6- D
The capacity of a red box is $$20\%$$ bigger than the capacity of a blue box and it can hold 30 books. Therefore, we want to find a number that $$20\%$$ bigger than that number is 30. Let $$x$$ be that number. Then:
$$1.20 × x = 30$$
Divide both sides of the equation by 1.2. Then:
$$x = \frac{30}{1.20}=25$$

7- A
The smallest number is $$-15$$. To find the largest possible value of one of the other five integers, we need to choose the smallest possible integers for four of them. Let $$x$$ be the largest number. Then:
$$-70 = (-15) + (-14) + (-13) + (-12) + (-11) + x→-70 =- 65 + x →x = -70 + 65 = -5$$

8- B
Since $$f(x)$$ is linear function with a negative slop, then when $$x=-2, f(x)$$ is maximum and when $$x=3, f(x)$$ is minimum. Then the ratio of the minimum value to the maximum value of the function is:
$$\frac{f(3)}{f(-2)}=\frac{-3(3)+1}{-3(-2)+1}=\frac{- 8}{7}$$

9- B
Ratio of women to men in city A: $$\frac{570}{600}=0.95$$
Ratio of women to men in city B: $$\frac{291}{300}=0.97$$
Ratio of women to men in city C: $$\frac{667}{700}=0.95$$
Ratio of women to men in city D: $$\frac{528}{550} =0.96$$

10- D
Percentage of men in city $$A = \frac{600}{1170}×100 = 51.28 \%$$
Percentage of women in city $$C = \frac{665}{1365} ×100 = 48.72\%$$
Percentage of men in city $$A$$ to percentage of women in city $$C$$
$$\frac{51.28}{48.72} = 1.05$$
