(a) $35

(b) $40

(c) $45

(d) $50

(a) 10

(b) 12

(c) 15

(d) 18

(a) 12

(b) 18

(c) 24

Ans: (c) 24

Solution: Let the number be x. Then, 60% of x = 48. Solving for x gives x = 48 / 0.60 = 80. Therefore, 30% of 80 is 0.30 * 80 = 24. - What is the value of a car after 3 years if it depreciates by 15% each year and its initial value is $20,000?

Ans: (c) 37

Solution: If 40% of the total number of students is represented by 25 girls, then 60% is represented by boys. So, let the total number of students be x. Then, 60% of x = boys = 0.60x. Solving for x gives x = 62.5. Therefore, there are 62.5 – 25 = 37.5 boys, which can be rounded to 37. - What is the cost price of a laptop sold at a profit of 25% if the selling price is $1250?
