A basket contains 3 red, 5 blue, and 2 green balls. What is the probability of drawing a green ball?
-
1/10
-
2/10
-
3/10
-
1/5
Correct Answer
A. 2/10Explanation
Total balls = 3 + 5 + 2 = 10. Probability of drawing a green ball = 2/10 = 1/5. This gives the likelihood of drawing one green ball. Probability is the likelihood of a specific event occurring and is calculated as the number of favorable outcomes divided by the total number of possible outcomes. Here, there are 2 green balls, and the total number of balls is 10. Therefore, the probability of drawing a green ball is 2 divided by 10, which simplifies to 1/5. This helps us understand how often an event can occur based on the total possibilities.Rate this question:

The sum of two numbers is 70, and one of the numbers is 25. What is the other number?
-
40
-
45
-
50
-
55
Correct Answer
A. 40Explanation
The second number is found by subtracting the known number from the total sum. 70 - 25 = 45. When you know the sum of two numbers and one of the numbers, you can find the other number by simple subtraction. In this case, the total sum of the numbers is 70, and one of the numbers is 25. Subtracting 25 from 70 gives us 45, which is the second number. This is a straightforward application of the addition and subtraction relationship.Rate this question:

If a shirt costs $50 and is sold for $60, what is the profit percentage?
-
15%
-
20%
-
25%
-
30%
Correct Answer
A. 20%Explanation
Profit percentage is calculated as Profit/Cost Price × 100. Profit = 60 - 50 = 10. Profit percentage = (10/50) × 100 = 20%. To calculate profit percentage, we use the formula: Profit Percentage = (Profit / Cost Price) × 100. First, we calculate the profit by subtracting the cost price ($50) from the selling price ($60). This gives a profit of $10. Then, we divide the profit by the cost price ($10 ÷ $50 = 0.2) and multiply by 100 to get the profit percentage, which is 20%. This shows how efficiently profit is made in relation to the cost.Rate this question:

A car travels 150 km in 3 hours. What is the average speed of the car?
-
45 km/h
-
50 km/h
-
55 km/h
-
60 km/h
Correct Answer
A. 50 km/hExplanation
Average speed = Distance / Time. So, 150 km ÷ 3 hours = 50 km/h. Average speed is calculated by dividing the total distance traveled by the total time taken. In this case, the car travels 150 kilometers in 3 hours, so the average speed is 150 ÷ 3 = 50 km/h. This gives us an idea of how fast the car is traveling on average throughout the journey, considering both speed and time.Rate this question:

If a train moves at a speed of 70 km/h, how much time will it take to travel 210 km?
-
2 hours
-
3 hours
-
4 hours
-
5 hours
Correct Answer
A. 3 hoursExplanation
Time = Distance / Speed. So, 210 km ÷ 70 km/h = 3 hours. To find the time it takes to travel a certain distance, use the formula: Time = Distance ÷ Speed. Here, the total distance is 210 kilometers, and the speed is 70 kilometers per hour. Dividing 210 by 70 gives us a time of 3 hours. This simple calculation helps us determine how long it will take to cover a specific distance at a given speed.Rate this question:

If a person buys a book for $12 and sells it for $15, what is the percentage profit?
-
25%
-
30%
-
35%
-
40%
Correct Answer
A. 25%Explanation
Percentage profit = (Profit / Cost Price) × 100. Profit = 15 - 12 = 3. So, Percentage profit = (3/12) × 100 = 25%. The percentage profit is found by calculating the profit and then dividing it by the cost price. In this case, the cost price of the item is $12, and the selling price is $15, so the profit is $3. The formula then gives us: (3 ÷ 12) × 100 = 25%. This shows the return on investment as a percentage, which helps understand the efficiency of a sale.Rate this question:

In a class of 40 students, 24 are boys. What percentage of the students are girls?
-
40%
-
45%
-
50%
-
60%
Correct Answer
A. 60%Explanation
The number of girls = 40 - 24 = 16. Percentage of girls = (16 / 40) × 100 = 40%. To find the percentage of girls in the class, we first subtract the number of boys (24) from the total number of students (40), which gives 16 girls. Then, we calculate the percentage of girls by dividing 16 by 40 and multiplying by 100. This gives us 40%, indicating the proportion of girls in the class relative to the total.Rate this question:

If the cost of 5 pens is $10, what is the cost of 8 pens?
-
$15
-
$16
-
$18
-
$20
Correct Answer
A. $16Explanation
Cost per pen = $10 ÷ 5 = $2. Therefore, the cost of 8 pens = 8 × $2 = $16. The cost per pen is calculated by dividing the total cost by the number of pens. Here, the total cost for 5 pens is $10, so the cost per pen is $2. To find the cost for 8 pens, we multiply the cost per pen ($2) by the number of pens (8), giving a total of $16. This calculation is useful for determining costs based on quantities.Rate this question:

A product originally costs $80. If it is sold at a 25% discount, what is the selling price?
-
$60
-
$55
-
$50
-
$75
Correct Answer
A. $60Explanation
The discount amount = 80 × 0.25 = 20. The selling price = 80 - 20 = 60. The discount on an item is calculated by multiplying the original price by the discount rate. In this case, the original price is $80, and the discount is 25%. Multiplying $80 by 0.25 gives $20 as the discount amount. Subtracting this from the original price results in a selling price of $60. This demonstrates how to apply discounts to a product's price.Rate this question:

The average of five numbers is 25. What is the sum of the numbers?
-
120
-
125
-
130
-
135
Correct Answer
A. 120Explanation
The sum of the numbers is calculated by multiplying the average by the number of values. So, 25 × 5 = 120. To find the sum of a set of numbers, multiply the average by the number of items. Here, we are told that the average of the 5 numbers is 25, so multiplying 25 by 5 gives us the sum of 120. This is a simple way to reverse the process when you know the average and the number of items in a set.Rate this question:

If a man sells an item for $50 at a 20% profit, what was the cost price of the item?
-
$40
-
$42
-
$44
-
$45
Correct Answer
A. $40Explanation
Selling price = Cost price + Profit. Let cost price be X. Then, 50 = X + 0.20X. Solving, X = 50 / 1.20 = 40. The cost price can be found by rearranging the formula: Selling price = Cost price + Profit. Here, the selling price is $50, and the profit is 20% of the cost price. By setting up the equation, 50 = X + 0.20X, we can solve for X (the cost price), which gives $40. This is an example of finding the original price of an item when the selling price and profit percentage are known.Rate this question:

A shopkeeper sells a product for $120 after giving a 10% discount. What is the original price of the product?
-
$130
-
$140
-
$150
-
$160
Correct Answer
A. $140Explanation
The selling price after a 10% discount is 90% of the original price. Let the original price be X. So, 0.90X = 120. Solving for X gives X = 120 ÷ 0.90 = 133.33. When a 10% discount is applied, the item is sold for 90% of its original price. To find the original price, we set up the equation 0.90X = 120, where X is the original price. Solving for X gives us $133.33, which is the price before the discount. This shows how to reverse calculate the original price after a discount.Rate this question:

A person spends 3 hours working and completes 60 units of work. How many units of work can they complete in 8 hours?
-
120
-
140
-
160
-
180
Correct Answer
A. 120Explanation
The number of units of work is proportional to time. If 60 units are completed in 3 hours, then in 8 hours, the worker would complete 60 × (8 / 3) = 160 units. The number of units of work completed is directly proportional to the amount of time spent. If 60 units are completed in 3 hours, then in 8 hours, the worker would complete 60 × (8 / 3) = 160 units. This is a simple application of direct proportion, where work and time are related in a linear fashion.Rate this question:
