1- D
Some of prime numbers are: $$2, 3, 5, 7, 11, 13$$
Find the product of two consecutive prime numbers:
$$2 × 3 = 6$$ (not in the options)
$$3 × 5 = 15$$ (bingo!)
$$5 × 7 = 35$$ (not in the options)

2- B
The question is this: 530.40 is what percent of 624?
Use percent formula:
$$part =\frac{percent}{100}× whole$$
$$530.40 =\frac{percent}{100}× 624$$
$$530.40 =\frac{percent× 624}{100}$$
$$⇒53040 = percent ×624$$
$$percent = \frac{53040}{624}= 85$$
530.40 is $$85 \%$$ of 624. Therefore, the discount is: $$100\% – 85\% = 15\%$$

3- B
If the score of Mia was 60, therefore the score of Ava is 30. Since, the score of Emma was half as that of Ava, therefore, the score of Emma is 15.

4- D
If 17 balls are removed from the bag at random, there will be one ball in the bag.
The probability of choosing a brown ball is 1 out of 18. Therefore, the probability of not choosing a brown ball is 17 out of 18 and the probability of having not a brown ball after removing 17 balls is the same.

5- B
Let $$x$$ be the smallest number. Then, these are the numbers:
$$x, x+1, x+2, x+3, x+4$$
$$average = \frac{sum \space of \space terms}{number \space of \space terms}$$
$$38 = \frac{x+(x+1)+(x+2)+(x+3)+(x+4)}{5}$$
$$38=\frac{5x+10}{5}$$
$$⇒ 190 = 5x+10 ⇒ 180 = 5x ⇒ x=36$$

6- C
The area of the floor is: $$6$$cm $$× 24$$ cm $$= 144$$ cm
The number is tiles needed $$= 144 ÷ 8 = 18$$

7- C
The weight of 12.2 meters of this rope is: $$12.2 × 600 g = 7320 g$$
$$1 kg = 1000 g$$, therefore, $$7320 g ÷ 1000 = 7.32 kg$$

8- C
$$4\%$$ of the volume of the solution is alcohol. Let $$x$$ be the volume of the solution.
Then: $$4\%$$ of $$x = 24$$ ml $$⇒ 0.04 x = 24 ⇒ x = 24 ÷ 0.04 = 600$$

9- B
$$average =\frac{sum \space of \space terms}{number \space of \space terms}$$
The sum of the weight of all girls is: $$18 × 60 = 1080$$ kg
The sum of the weight of all boys is: $$32 × 62 = 1984$$ kg
The sum of the weight of all students is: $$1080 + 1984 = 3064$$ kg
$$average =\frac{3064}{50}= 61.28$$

10- C
Let $$x$$ be the original price.
If the price of a laptop is decreased by $$10\%$$ to \$360, then: $$90 \%$$ of $$x=360⇒ 0.90x=360 ⇒ x=360÷0.90=400$$
