- A.
246
- B.

- D.
15
Correct Answer
D. 15Explanation
By rearranging the equation, we can isolate the variable a. Adding 5 to both sides of the equation gives us 17a = 255. Then, dividing both sides by 17 gives us a = 15. Therefore, the value of a that satisfies the equation 17a - 5 = 250 is 15.Rate this question:

What is the sum of (2a + 5b) and (a + 7b)
- A.
6a + 12b
- B.
9a + 6b
- C.
3a + 12b
- D.
None of the above
Correct Answer
C. 3a + 12bExplanation
The given expression asks for the sum of (2a + 5b) and (a + 7b). To find the sum, we can combine like terms. The coefficients of 'a' in both terms are 2 and 1 respectively, so the sum of the 'a' terms is 2a + 1a = 3a. Similarly, the coefficients of 'b' in both terms are 5 and 7 respectively, so the sum of the 'b' terms is 5b + 7b = 12b. Therefore, the sum of (2a + 5b) and (a + 7b) is 3a + 12b.Rate this question:

The G.C.D of two numbers is 15 and their L.C.M is 225. If one number is 45, what is the other one?
- A.
15
- B.
75
- C.
105
- D.
None of these
Correct Answer
B. 75Explanation
The greatest common divisor (GCD) of two numbers is the largest number that divides both numbers without leaving a remainder. The least common multiple (LCM) of two numbers is the smallest number that is divisible by both numbers. In this case, the GCD of the two numbers is 15 and the LCM is 225. Since one number is given as 45, we can find the other number by dividing the LCM by the given number. 225 divided by 45 equals 5, so the other number is 5 times the GCD, which is 5 times 15, equal to 75. Therefore, the other number is 75.Rate this question:

7.2 divided by 0.8
- A.
0.09
- B.
0.9
- C.
9
- D.
9.9
Correct Answer
C. 9Explanation
When dividing 7.2 by 0.8, we can think of it as finding out how many times 0.8 can be subtracted from 7.2. By subtracting 0.8 from 7.2 repeatedly, we get the following: 7.2 - 0.8 = 6.4, 6.4 - 0.8 = 5.6, 5.6 - 0.8 = 4.8, 4.8 - 0.8 = 4, 4 - 0.8 = 3.2, 3.2 - 0.8 = 2.4, 2.4 - 0.8 = 1.6, 1.6 - 0.8 = 0.8, 0.8 - 0.8 = 0. Since we subtracted 0.8 a total of 9 times, the answer is 9.Rate this question:

10 kg rice costs rs 367 what is the price for 1 and a half kg of rice
- A.
67
- B.
55.05
- C.
55
- D.
36.7
Correct Answer
B. 55.05Explanation
The price for 1 kg of rice can be found by dividing the total cost of 10 kg rice by 10. Therefore, 1 kg of rice costs 367/10 = 36.7 rs. To find the price for 1 and a half kg of rice, we can multiply the price for 1 kg by 1.5. Hence, the price for 1 and a half kg of rice is 36.7 * 1.5 = 55.05 rs.Rate this question:

How many gross of books did a dealer buy if he bought 20160 books
- A.
165
- B.
789
- C.
140
- D.
49
Correct Answer
C. 140Explanation
The dealer bought 20160 books. To find out how many gross of books he bought, we need to divide the total number of books by 144 (since there are 144 books in a gross). 20160 divided by 144 equals 140, so the dealer bought 140 gross of books.Rate this question:

The sum of two angles is 180 degrees what are they called
- A.
Complimentary angles
- B.
Straight angles
- C.
Supplementary angles
- D.
Right angle
Correct Answer
C. Supplementary anglesExplanation
The sum of two angles that equals 180 degrees is called supplementary angles. Supplementary angles are two angles that, when added together, form a straight angle. A straight angle measures 180 degrees, so any two angles that add up to 180 degrees are considered supplementary angles.Rate this question:

Base = 0.8 dm height=20mm Area = ?
- A.
16 sq dm
- B.
16 sq cm
- C.
16 sq mm
- D.
1.6 sq cm
Correct Answer
B. 16 sq cmExplanation
The given question asks for the area of a shape with a base of 0.8 dm and a height of 20 mm. To find the area, we need to convert the base and height to the same unit of measurement. Since 1 dm is equal to 10 cm, the base can be converted to 8 cm. The formula for the area of a shape is base multiplied by height, so the area is 8 cm multiplied by 20 mm. Since 1 cm is equal to 10 mm, the area can be calculated as 8 cm multiplied by 2 cm, which equals 16 sq cm. Therefore, the correct answer is 16 sq cm.Rate this question:

How much of wire will be needed to fence a field 3 times over with dimensions 225m and 150 m
- A.
3 km
- B.
2.25 km
- C.
101250 m
- D.
1125 m
Correct Answer
B. 2.25 kmExplanation
To fence a field 3 times over, we need to calculate the perimeter of the field and then multiply it by 3. The perimeter of a rectangle is calculated by adding the lengths of all its sides. In this case, the dimensions of the field are given as 225m and 150m. So, the perimeter of the field is (225 + 150 + 225 + 150) = 750m. Multiplying this by 3 gives us 2250m, which is equal to 2.25 km. Therefore, the correct answer is 2.25 km.Rate this question:
