- A.
9
- B.
10
- C.
11
- D.
12
Correct Answer
B. 10Explanation
The next triangular number is 10 because each triangular number is the sum of all the natural numbers up to a certain number. In this case, the first triangular number is 1, the second is 3 (1+2), and the third is 6 (1+2+3). To find the next triangular number, we add the next natural number, which is 4, to the previous triangular number. So, 6+4=10, making it the next triangular number.Rate this question:

- A.
7/50
- B.
8/50
- C.
7/10
- D.
8/10
Correct Answer
C. 7/10Explanation
To subtract fractions, we need to have a common denominator. In this case, the common denominator is 30. So, we rewrite 9/10 as 27/30 and 1/15 as 2/30. Now, we can subtract the numerators and keep the denominator the same: 27/30 - 2/30 = 25/30. Simplifying the fraction, we get 5/6. However, this is not one of the options provided. Therefore, the correct answer is not available.Rate this question:

20% of the lettuce eaten is 'waste'. I eat 50g of lettuce. How many grams of 'waste' is this?
- A.
10g
- B.
20g
- C.
30g
- D.
40g
Correct Answer
A. 10gExplanation
If 20% of the lettuce eaten is 'waste', it means that for every 100g of lettuce eaten, 20g is waste. Since I eat 50g of lettuce, I can calculate the amount of waste by finding 20% of 50g. 20% of 50g is 10g, so the correct answer is 10g.Rate this question:

It costs £95 to hire a car for 5 days. How much would it cost to hire the same car for 7 days at the same rate?
- A.
£97
- B.
£126
- C.
£133
- D.
£142.50
Correct Answer
C. £133Explanation
To find out how much it would cost to hire the same car for 7 days at the same rate, we can set up a proportion. We know that the cost is directly proportional to the number of days. So, we can set up the proportion: 5 days/£95 = 7 days/x. Cross-multiplying, we get 5x = 7 * £95. Solving for x, we find that x = £133. Therefore, it would cost £133 to hire the same car for 7 days at the same rate.Rate this question:

Solve the equation 2x - 1= 9
- A.
X=4
- B.
X=5
- C.
X=6
- D.
X=8
Correct Answer
A. X=4Explanation
To solve the equation 2x - 1 = 9, we need to isolate the variable x. First, we add 1 to both sides of the equation to get 2x = 10. Then, we divide both sides by 2 to solve for x, giving us x = 5. Therefore, the correct answer is x = 5.Rate this question:

Which one of the following cylinders has radius 3cm and height 12cm?
- A.
A( 3cm x12cm)
- B.
B(12cmx 6cm)
- C.
C(12cmx3cm)
- D.
D(6cmx12cm)
Correct Answer
B. B(12cmx 6cm)Explanation
The cylinder with dimensions 12cm x 6cm has a radius of 3cm and a height of 12cm. The radius is the distance from the center of the circular base to the edge, and since the radius is 3cm, the diameter (which is twice the radius) would be 6cm. The height of the cylinder is given as 12cm, which matches the height given in the question. Therefore, option b is the correct answer.Rate this question:

The area of the letter L shown in Fig. 0794 is
- A.
38 cm²
- B.
40 cm²
- C.
44 cm²
- D.
50 cm²
Correct Answer
C. 44 cm²Explanation
The area of the letter L can be calculated by finding the sum of the areas of the individual shapes that make up the letter. In this case, the letter L is made up of a rectangle and a right triangle. The area of the rectangle can be calculated by multiplying its length and width, which is 4 cm × 11 cm = 44 cm². The area of the right triangle can be calculated by multiplying its base and height and then dividing by 2, which is (9 cm × 5 cm) / 2 = 22.5 cm². Adding the areas of the rectangle and triangle, we get 44 cm² + 22.5 cm² = 66.5 cm². Since this is not one of the given answer choices, the correct answer must be 44 cm².Rate this question:

D. 20Explanation
When the food at 16º C is placed in the refrigerator with a temperature of -4º C, there is a difference of 20 degrees Celsius between the two temperatures. The food will eventually reach the temperature of the refrigerator, causing its temperature to fall by 20 degrees Celsius. Therefore, the correct answer is 20.Rate this question:

A child's party dress is to be finished with lace. It needs 2m around the bottom, 0.18m around each sleeve and 0.6m around the neck. How much lace will be left from a piece 3m long?
- A.
0.04m
- B.
0.22m
- C.
0.58m
- D.
0.76m
Correct Answer
B. 0.22mExplanation
The total length of lace needed is 2m + 0.18m + 0.18m + 0.6m = 2.96m. Since the piece of lace is 3m long, the amount of lace left is 3m - 2.96m = 0.04m. Therefore, the correct answer is 0.04m.Rate this question:
